In the Linux kernel, the following vulnerability has been resolved: ntb: Store original DMA address for future release The DMA API requires that dma_free_attrs receive the exact dma_handle originally returned by the allocation function. Do not modify it.

In the Linux kernel, the following vulnerability has been resolved: drm/tegra: gr2d/gr3d: Initialize address register map before HOST1X client is registered The host1x_client_register() function is called just prior to register map initialization loop, making the device available to userspace. This may result in userspace attempting to submits a job before the register map is initialized. Address this by moving register initialization before host1x client registration.

In the Linux kernel, the following vulnerability has been resolved: crypto: tegra - Return ENOMEM when input buffer allocation fails for ccm Ensure the ENOMEM error value is set when the input buffer allocation fails in tegra_ccm_do_one_req.

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix buffer head management in ocfs2_read_blocks() In ocfs2_read_blocks(), caller should't assume that buffer head returned by 'sb_getblk()' is exclusively owned and so 'put_bh()' always drops b_count from 1 to 0. If it is not so, buffer head remains on hold and likely to be returned by the next call to 'sb_getblk()' unchanged - that is, with BH_Uptodate bit set even if it has failed validation previously, thus allowing to insert that buffer head into OCFS2 metadata cache and submit it to upper layers. To avoid such a scenario, BH_Uptodate should be cleared immediately after 'validate()' callback has detected some data inconsistency.

In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Properly support implicit ODP rereg_mr Due to all the child mkeys in the implicit ODP configuration we cannot change anything in place for the parent mkey. Instead the whole thing needs to be rebuilt if any change is requested. If the user does not specify a translation then force the implicit values which will then fall through the logic into mlx5_ib_reg_user_mr() to allocate a completely new MR. Since implicit children were also touching the mr->pd, this removes another case where the access was racy.

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix circular locking dependency in ocfs2_dio_end_io_write A circular locking dependency involves INODE_ALLOC_SYSTEM_INODE, EXTENT_ALLOC_SYSTEM_INODE, and ORPHAN_DIR_SYSTEM_INODE. 1. ocfs2_mknod() acquires INODE_ALLOC then EXTENT_ALLOC. 2. ocfs2_dio_end_io_write() acquires EXTENT_ALLOC for unwritten extents, then ORPHAN_DIR via ocfs2_del_inode_from_orphan() while still holding EXTENT_ALLOC. 3. ocfs2_wipe_inode() acquires ORPHAN_DIR then INODE_ALLOC via ocfs2_remove_inode. Break the cycle in ocfs2_dio_end_io_write() by freeing the allocation contexts (releasing EXTENT_ALLOC) before acquiring ORPHAN_DIR.

In the Linux kernel, the following vulnerability has been resolved: afs: Fix leak of ungot volume Fix afs_lookup_volume_rcu() so that it doesn't leak a dying volume if afs_try_get_volume() fails.

In the Linux kernel, the following vulnerability has been resolved: afs: Fix vllist leak Fix a leak of the new vllist in afs_update_cell() in the event that it is an empty list (nr_servers == 0), in which case the old list isn't displaced unless the old list is also empty.

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Fix event length with forced 8-byte alignment When RB_FORCE_8BYTE_ALIGNMENT is true, rb_calculate_event_length() reserves the space of event->array[0] for placing the data length and rb_update_event() stores the data length in event->array[0] accordingly. As a result the whole event length will add extra 4 bytes for sizeof(event.array[0]) unconditionally. But ring_buffer_event_length() only subtracts the sizeof(event->array[0]) for events larger than RB_MAX_SMALL_DATA + sizeof(event->array[0]). As a result, small events on architectures with RB_FORCE_8BYTE_ALIGNMENT=true report a data length that is 4 bytes larger than expected. To fix it, add the RB_FORCE_8BYTE_ALIGNMENT as a condition to subtract the size of that length field whenever RB_FORCE_8BYTE_ALIGNMENT is true. This issue is observed in a riscv64 kernel with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, when we run ftrace selftest trace_marker_raw.tc, we get the weird log: for cases where the id is 1..100, the number of data field is 8*N, but once id exceeds 100, the number of data field becomes 8*N+4: # 1 buf: 58 00 00 00 80 5e d1 63 (number of data field is 8*1) ... # a buf: 58 ... (number of data field is 8*2) ... # 64 buf: 58 ... (number of data field is 8*13) # 65 buf: 58 ... (number of data field is 8*13+4) After applying this change, the number of data field keeps being 8*N+4 consistently.

In the Linux kernel, the following vulnerability has been resolved: ipvs: use parsed transport offset in TCP state lookup TCP state handling reparses the skb to find the TCP header. For IPv6 it uses sizeof(struct ipv6hdr), while the surrounding IPVS code already parsed the packet with ip_vs_fill_iph_skb() and has the real transport-header offset in iph.len. This makes TCP state handling look at the wrong bytes when an IPv6 packet carries extension headers. Use the parsed transport offset passed down from ip_vs_set_state() when reading the TCP header. For IPv4 and for IPv6 packets without extension headers, the passed offset matches the previous value.

In the Linux kernel, the following vulnerability has been resolved: arm64: dts: renesas: ironhide: Describe inline ECC carveouts The DBSC5 DRAM controller protects DRAM content using inline ECC. The inline ECC utilizes areas of DRAM for its operation, which are in the DRAM address range, but must not be accessed or modified. Describe the inline ECC carveout areas used by the DBSC5 controller on this hardware as reserved-memory, which must not be accessed. Include DRAM areas which are unprotected by ECC as well, those are parts of the DRAM which directly precede the ECC carveout. In case of high DRAM utilization, unless the inline ECC carveouts are properly reserved, Linux may use and corrupt the memory used by the DBSC5 DRAM controller for inline ECC, which would lead to the system becoming unstable.

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Write ESR_EL2 for injected nested SError exceptions kvm_inject_el2_exception() writes ESR_EL2 for synchronous exceptions but not for SError. enter_exception64() does not write ESR_ELx for any exception type, so the constructed syndrome is dropped. A guest L2 hypervisor taking a nested SError observes stale ESR_EL2. This affects both kvm_inject_nested_serror() and the EASE path in kvm_inject_nested_sea(). Write ESR_EL2 for except_type_serror, matching except_type_sync.

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/tas2781: Cancel async firmware request at unbind TAS2781 HDA I2C and SPI queue RCA firmware loading from component bind with request_firmware_nowait(). The firmware loader keeps the callback module pinned and holds a device reference, but the callback still uses driver-private HDA state. Component unbind removes controls and DSP state immediately. Later device removal tears down the TAS2781 private data, including codec_lock. If the async firmware callback runs after unbind has started, it can operate on state that is being torn down. Cancel or synchronize the async firmware request before removing controls and DSP state. A queued callback is cancelled, and an already-running callback is allowed to finish before unbind continues.

In the Linux kernel, the following vulnerability has been resolved: crypto: xilinx-trng - Remove crypto_rng interface Implementing the crypto_rng interface has no purpose, as it isn't used in practice. It's being removed from other drivers too. Just remove it. This leaves hwrng, which is actually used. Tagging with 'Cc stable' due to the bugs that this removes: - xtrng_trng_generate() sometimes returned success even when it didn't fill in all the bytes. - It was possible for xtrng_trng_generate() and xtrng_hwrng_trng_read() to run concurrently and interfere with each other, as the locking code in xtrng_hwrng_trng_read() was broken.

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Validate CRIU-restored IDs before idr_alloc The KFD CRIU restore flow restores previously saved object IDs from userspace. For event restore: kfd_criu_restore_event() -> create_signal_event() / create_other_event() -> allocate_event_notification_slot() -> idr_alloc(..., *restore_id, *restore_id + 1, ...) For BO restore: criu_restore_memory_of_gpu() -> idr_alloc(..., bo_priv->idr_handle, ...) In both cases, the restored ID comes from userspace-provided CRIU data. idr_alloc() expects the ID range values to fit within signed int limits. If a restored ID is larger than INT_MAX, it can trigger a WARN in the IDR layer. A kernel WARN is undesirable because it prints a warning trace and may cause a panic or reboot on systems with panic_on_warn enabled. Smatch reported these paths as allowing unchecked userspace values to reach idr_alloc(). Add INT_MAX validation before using restored IDs in: - kfd_criu_restore_event() - criu_restore_memory_of_gpu() If the restored ID is invalid, return -EINVAL. This prevents invalid restore data from reaching the IDR layer and avoids WARN-triggering paths, while keeping valid restore behavior unchanged.

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the attribute-list entry in ntfs_read_inode_mount() The $MFT attribute-list walk in ntfs_read_inode_mount() validates each entry only with "(u8 *)al_entry + 6 > al_end" and "(u8 *)al_entry + le16_to_cpu(al_entry->length) > al_end", but then reads al_entry->lowest_vcn (an __le64 at offset 8) and al_entry->mft_reference (offset 16) -- fields beyond the 6 bytes proven in range. al_entry->length is attacker-controlled and only required non-zero, so a short entry (e.g. length 8) placed at the tail passes both checks while the lowest_vcn / mft_reference reads fall past al_end. al_end is ni->attr_list + attr_list_size (the on-disk size); the buffer is kvzalloc(round_up(attr_list_size, SECTOR_SIZE)), so the sector rounding usually absorbs the over-read -- but when attr_list_size is a multiple of SECTOR_SIZE there is no slack and a crafted $MFT attribute list produces an out-of-bounds read at mount time. Validate the entry with ntfs_attr_list_entry_is_valid() (added in patch 1/3) before dereferencing it, matching the bound the other attribute-list walks now use. The validator already requires the length to cover the fixed header, which makes the separate "!al_entry->length" check redundant, so drop it too.

In the Linux kernel, the following vulnerability has been resolved: ntfs3: Allocate iomap inline_data using alloc_page This fixes a BUG reported in iomap_write_end_inline: iomap_inline_data_valid checks that the inline_data fits within a page. If the inline_data is allocated with kmemdup there's no guarantee that it's page-aligned, so the check sometimes fails. Allocate it with alloc_page to ensure it's page-aligned.

In the Linux kernel, the following vulnerability has been resolved: alpha/PCI: Add security_locked_down() check to pci_mmap_resource() Currently, Alpha's pci_mmap_resource() does not check security_locked_down(LOCKDOWN_PCI_ACCESS) before allowing userspace to mmap PCI BARs. The generic version has had this check since commit eb627e17727e ("PCI: Lock down BAR access when the kernel is locked down") to prevent DMA attacks when the kernel is locked down. Add the same check to Alpha's pci_mmap_resource().

In the Linux kernel, the following vulnerability has been resolved: tipc: avoid busy looping in tipc_exit_net() Blamed commit introduced a busy-wait loop in tipc_exit_net() to wait for pending UDP bearer cleanup works to complete: while (atomic_read(&tn->wq_count)) cond_resched(); This loop can busy-wait for a long time if cond_resched() is a NOP. This typically happens if the netns exit is executed by a high priority task, or under kernels configured without preemption (CONFIG_PREEMPT_NONE). In such cases, it wastes CPU cycles and can lead to soft lockups. Fix this by replacing the busy loop with wait_var_event(), allowing the thread to sleep properly until the work queue count reaches zero. Accordingly, update cleanup_bearer() to use atomic_dec_and_test() and wake_up_var() to wake up the waiter when the count drops to zero. This uses the global wait queue hash table, avoiding the need to bloat struct tipc_net with a wait_queue_head_t. The atomic_dec_and_test() provides the necessary memory barrier to ensure the wakeup is not missed.

In the Linux kernel, the following vulnerability has been resolved: bpf: Add missing access_ok call to copy_user_syms As reported by sashiko we use __get_user without prior access_ok call on the user space pointer. Adding the missing call for the whole pointer array. Plus removing the err check in the error path, because it's not needed and also we can return -ENOMEM directly from the first kvmalloc_array fail path.

Cross Site Scripting vulnerability in Netgate pfSense Plus software versions <= 26.03 pfSense CE software versions <= 2.8.1 allows a remote attacker to execute arbitrary code via the captive_portal_status.widget.php file

An issue in HiDPT/ Weyon HiDPTAndroid Hi3751V350 Hi3751V352E_DMO allows a remote attacker to execute arbitrary code via the Android Debug Bridge (ADB) daemon (adbd)

PowerJob Worker version 5.1.2 (and likely earlier versions) exposes the /worker/deployContainer HTTP endpoint without authentication on the default transport port. This allows a remote attacker to execute arbitrary code.

Cross-Site Scripting (XSS) vulnerability in the RSS Widget of Netgate pfSense Plus (versions 26.03, 25.11.1) and pfSense CE (version 2.8.1) allows remote authenticated attackers to inject arbitrary JavaScript via malicious content in an RSS feed title. The injected script executes in the browser of any authenticated user who views the dashboard, due to insufficient sanitization of feed title data before rendering in the widget.

In DocsGPT 0.15.0 and below, the application provides a custom prompt feature that allows users to define prompt content used during chatbot interactions. This functionality renders user-supplied prompt data using Jinja templates without input sanitization or sandboxing. An unauthenticated attacker can inject malicious template expressions, leading to a server-side template injection (SSTI) vulnerability that can be exploited to achieve full remote code execution (RCE).
