CVE-2026-46132

CVE-2026-46132 - Linux kernel on multiple distros : The flaw is a stack information leak in net/rtnetlink when reporting VF info via IFLA_VF_BROADCAST. A local unprivileged process can trigger RTM_GETLINK and copy a partially uninitialized 32-byte field (vf_broadcast) from the stack, leaking up t...

CVE-2026-46145

The CVE-2026-46145 vulnerability affects the Linux kernel, specifically the RDMA/mana component. A user-supplied rx_hash_key_len value supplied via a uAPI structure is blindly passed to memcpy, enabling localized kernel memory corruption if bounds checks are not enforced. Reports from multiple so...

CVE-2026-46227

CVE-2026-46227 describes a race in the Linux kernel SCTP SENDALL path. The sctp_sendmsg() loop over ep->asocs caches the next entry in @tmp, then calls sctp_sendmsg_to_asoc() after dropping the socket lock, allowing a second thread to peel off the cached association and migrate it to a new end...

CVE-2026-52908

CVE-2026-52908 affects the Linux kernel RDMA path: during rereg_mr, changing IB_MR_REREG_ACCESS from RO to RW requires re-evaluating the umem to ensure proper RW pinning. The fix introduces an ib_umem_check_rereg() hook that each driver must call before processing IB_MR_REREG_ACCESS; mlx4 retains...

CVE-2022-50232

CVE-2022-50232 affects the Linux kernel on arm64 with FEAT_EPAN: UXN was not set on swapper PTEs, causing idmap_kpti_install_ng_mappings to panic when accessing __idmap_kpti_flag. Upstream fix sets UXN on swapper page tables; originated from a boot-flow refactor (commit c3cee924bd85) and a simple...

CVE-2022-50373

The CVE-2022-50373 entry describes a race in the Linux kernel's DLM lowcomms path: in fs/dlm, between queue_work() in _dlm_lowcomms_commit_msg() and srcu_read_unlock(). The race can allow the final reference of a dlm_msg to be taken by queue_work(), causing msg->idx to contain garbage. A patch...

CVE-2025-38372

CVE-2025-38372 : The Linux kernel patch for RDMA/mlx5 implicit ODP handling fixes an unsafe xarray access by replacing __xa_store() and __xa_erase() (which were used without proper locking) with xa_store() and xa_erase(), which perform the necessary locking internally. This resolves a suspicious ...

CVE-2025-38402

The CVE concerns the Linux kernel IDPF driver RSS handling. The vulnerability arises when RSS is not supported: the code returns a 0 RSS key size, while a -EOPNOTSUPP path may be cast to a 32-bit size, potentially producing an invalid allocation size. This can lead to an allocation failure on sys...

CVE-2025-38407

CVE-2025-38407 (Linux kernel, RISC‑V) is addressed by replacing the dynamic percpu boot data area with a statically allocated array in the kernel image to fix boot on NUMA SMP configurations.

Upstream kernel...

CVE-2026-31787

CVE-2026-31787 affects the Linux kernel, specifically the xen/privcmd mapping flow. The root cause is a double-free in the VMA splitting path when userspace performs partial munmap() on a privcmd mapping. Because privcmd_vm_ops defines .close but not .may_split or .open, the kernel may_split() pe...

CVE-2026-43011

The CVE-2026-43011 issue concerns the Linux kernel net/x25 path where a skb may be freed twice due to a double-free path: if alloc_skb fails in x25_queue_rx_frame, kfree_skb(skb) is called, and later x25_backlog_rcv may free the same skb again, causing a crash/DoS. Public advisories confirm this ...

CVE-2026-43490

The CVE-2026-43490 entry concerns the Linux kernel ksmbd SMB server. The flaw arises in smb_inherit_dacl() where the code validates a fixed SID header but not the variable-length SID described by sid.num_subauth, allowing a malformed inheritable ACE to advertise more subauthorities than present. ...
