CVE-2026-31422 affects the Linux kernel’s net/sched subsystem. The vulnerability occurs in flow_change() where tcf_block_q() dereferences q->handle to derive a default baseclass for shared blocks, while block->q can be NULL for shared blocks. The fix adds a check of tcf_block_shared() befor...

CVE-2026-31444

CVE-2026-31444 affects ksmbd in the Linux kernel. The vulnerability arises from two flaws in the oplock publication sequence inside smb_grant_oplock(): (1) opinfo is linked into ci->m_op_list before add_lease_global_list(), so if that call fails, a freed node is dereferenced by concurrent read...

CVE-2026-31447

CVE-2026-31447 affects the Linux kernel ext4, where mounting a filesystem with bigalloc and s_first_data_block != 0 is rejected.

CVE-2026-31454

Summary: CVE-2026-31454 affects the Linux kernel's XFS code. In xfs_inode_item_push() and xfs_qm_dquot_logitem_push(), the AIL lock is dropped to perform buffer IO, which can allow a log item to be freed during reclaim. A subsequent spin_lock() may dereference lip->li_ailp, causing a use-after...

CVE-2026-31491

In the Linux kernel’s RDMA/irdma component, CVE-2026-31491 stems from depth calculation functions that fail to properly guard against U32_MAX inputs for SQ/RQ/SRQ sizes. The issue can cause integer overflow and truncation, leading to the function returning success when it should fail. Public repo...

CVE-2026-31542

CVE-2026-31542 affects the Linux kernel x86/platform/uv component. When a socket is deconfigured, it is mapped to SOCK_EMPTY (0xffff) instead of NUMA_NO_NODE, causing a panic during allocation of UV hub info structures and potentially DoS. The fixes patch the behavior to allocate on valid NUMA no...

CVE-2026-31566

CVE-2026-31566 concerns the Linux kernel amdgpu driver (amdgpu_amdkfd_submit_ib).

The CVE-2026-31641 entry relates to the Linux kernel rxrpc token parsing bug. A heap buffer overflow could occur when rxrpc_preparse_xdr_yfs_rxgk() reads raw key and ticket lengths from an XDR token, applies round_up(x,4), and then uses the rounded values for validation/allocation, while the unro...

CVE-2026-31660

The CVE-2026-31660 entry concerns the Linux kernel NFC pn533 driver. The root cause is that pn532_receive_buf() may hand a complete frame to pn533_recv_frame() before allocating a fresh receive buffer; if alloc_skb() fails, the callback returns 0 while bytes have already been consumed, leaving re...

CVE-2026-31667

CVE-2026-31667 concerns the Linux kernel’s uinput and ff-core, where a circular locking dependency could cause a local deadlock when a force-feedback gamepad is used. The concrete sequence involves four lock paths that form a cycle: ff->mutex, udev->mutex, input_mutex, dev->mutex, and ba...

CVE-2026-43140

The CVE-2026-43140 vulnerability affects the Linux kernel HID magicmouse driver. Fake USB devices could present their own report descriptors such that input_mapping() does not call, leaving msc->input NULL and causing a crash later. The issue is resolved by detecting this condition in input_co...

CVE-2026-43150

The CVE-2026-43150 issue affects the Linux kernel’s perf/arm-cmn component, where the kernel now rejects unsupported CMN hardware configurations. The root cause is the kernel’s prior assumptions about maximum sizes and counts for CMN models and revisions, which could allow larger or unknown confi...

CVE-2026-43216

Summary of CVE-2026-43216 : In the Linux kernel, skb_may_tx_timestamp() could acquire sock::sk_callback_lock in IRQ context, risking a deadlock if the lock was already write-locked on the same CPU. The fix drops the lock and uses READ_ONCE() / WRITE_ONCE() to safely access and clear the pointers ...

CVE-2026-43222

In the Linux kernel, the media: verisilicon: AV1 driver patch fixes a buffer-size miscalculation for tile information. The tile info structure (row_sb, col_sb, start_pos, end_pos) requires AV1_MAX_TILES × 16 bytes; using the incorrect define caused writes to non-allocated memory, risking memory c...

CVE-2026-43233

CVE-2026-43233 affects the Linux kernel nf_conntrack_h323 decoder (decode_choice), where a boundary check incorrectly used an uninitialized length and may read past the bitstream end, enabling a remote heap-buffer-overflow via a crafted Q.931 SETUP message to port 1720. The public disclosures des...

CVE-2026-43338

CVE-2026-43338 affects the Linux kernel with the Btrfs filesystem. The issue arises because qgroup ioctls do not reserve transaction space, allowing -ENOSPC scenarios during quota-tree updates and delayed refs, which can abort transactions and enable a DoS condition. Vendors have published adviso...

CVE-2026-43345

Summary: The CVE concerns the Linux kernel IPA driver. For IPA v5.0+, the event ring index field moved from CH_C_CNTXT_0 to CH_C_CNTXT_1. The register definition intended to define this field in CH_C_CNTXT_1 but used the old identifier ERINDEX instead of CH_ERINDEX, causing an incorrect event rin...

CVE-2026-43351

The CVE-2026-43351 issue affects the Linux kernel’s KVM on arm64 when creating a virtual GIC. If vgic_allocate_private_irqs_locked() fails, kvm_vgic_create() can exit before vgic dist regions are initialised, and kvm_vgic_dist_destroy() may then attempt to free uninitialised data, risking a crash...

CVE-2026-43386

The CVE-2026-43386 issue affects the Linux kernel rtl8723bs component, specifically in the rtw_restruct_wmm_ie path, where an insufficiently guarded access can cause an out-of-bounds read.

CVE-2026-45889

Summary: CVE-2026-45889 affects the Linux kernel’s Multipath TCP (MPTCP). The root cause is incorrect accounting for Out-of-Order (OoO) data in mptcp_rcvbuf_grow(), causing the MPTCP receive buffer to drift toward tcp_rmem[2]. The vulnerability is linked to a subtle race during rcvspace initializ...

CVE-2026-45894

The CVE-2026-45894 issue affects the Linux kernel IOMMU VT-d Scalable Mode PASID handling. When a PASID table entry is torn down, the current code zeros the full 64-byte structure while P=1, risking a torn read if hardware fetches the 64 bytes concurrently. Mitigation directs an ownership handsha...

CVE-2026-45916

CVE-2026-45916 affects the Linux kernel power_supply (sbs-battery) driver. The issue is a race between IRQ handling and power_supply handle lifecycle: requesting IRQ with devm_ before allocating/registering the power_supply handle can cause an interrupt after the handle is freed but before IRQ un...

CVE-2026-45924

Summary: CVE-2026-45924 affects ksmbd in the Linux kernel. The vulnerability arises because ksmbd_vfs_kern_path_end_removing() is not called on certain error paths, leaving inode locks and references unbalanced after a prior ksmbd_vfs_kern_path_start_removing(). This can cause potential deadlocks...

CVE-2026-45943

The CVE-2026-45943 issue affects the Linux kernel's erofs filesystem, specifically a NULL pointer dereference when handling ztailpacking pclusters due to inline data not being validated before adding pclusters to I/O chains. The provided sources confirm the root cause and a fix: reading the inlin...
