CVE-2026-23084

CVE-2026-23084 affects the Linux kernel be2net driver. The vulnerability arises when be_cmd_get_mac_from_list() is called with pmac_id_valid == false and pmac_id == NULL, which can cause a NULL pointer dereference. The fix, per the description, is to pass the address of a stub variable to the fun...

CVE-2026-43472

The CVE describes a Linux kernel unshare(2) bug: when CLONE_NEWNS is requested and current->fs wasn’t previously shared, copy_mnt_ns() could receive a non-private fs_struct. If copy_mnt_ns() succeeds but a subsequent copy_cgroup_ns() fails, the destroyed namespace can leave current->fs->...

CVE-2025-71225

CVE-2025-71225: Linux kernel vulnerability in RAID update path. When updating raid_disks via sysfs, freeze_array may unblock before queued r1bio structures are released, causing free_r1bio() to access memory with the old raid_disks/mempool configuration. This can lead to out-of-bounds access and ...

CVE-2026-23218

CVE-2026-23218 affects the Linux kernel (loongson-64bit GPIO). The root cause is an incorrect NULL check in loongson_gpio_init_irqchip() after devm_kcalloc(), where chip->parent was checked instead of chip->irq.parents. This mischeck can lead to a NULL dereference during IRQ chip init. The ...

CVE-2026-23220

CVE-2026-23220 – Linux kernel ksmbd infinite loop fix : In ksmbd, when a signed SMB2 request fails verification, __process_request() triggers an error path that calls set_smb2_rsp_status() and resets next_smb2_rcv_hdr_off to zero. This loses the pointer to the next command in the chain, so is_cha...

CVE-2026-23228

The CVE-2026-23228 issue is in the Linux kernel smb server (ksmbd) where, on ksmbd_tcp_new_connection() failure, free_transport() did not decrement active_num_conn, leaking the counter.

CVE-2026-31714

The CVE-2026-31714 issue affects the Linux kernel F2FS component, where a memory leak occurs in f2fs_rename() due to an unpaired call to f2fs_free_filename() after f2fs_setup_filename() was added in commit 40b2d55e0452. Exploitation details are local (AV:L/AC:L) with a high availability impact (A...

CVE-2026-43076

The vulnerability CVE-2026-43076 affects the ocfs2 filesystem in the Linux kernel. When reading an inode from disk, ocfs2_validate_inode_block() did not validate the i_size of inline data against the inline data capacity (id_count). A corrupted filesystem could make i_size exceed id_count, causin...

CVE-2026-43113

In the Linux kernel, CVE-2026-43113 affects the wl1251 Wi‑Fi driver. The function wl1251_tx_packet_cb() uses the firmware completion ID (a raw u8) to index a fixed 16-entry wl->tx_frames[] array without validating that the ID fits. The callback can dereference out-of-range IDs. The fix rejects...

CVE-2026-43452

CVE-2026-43452 affects the Linux kernel netfilter x_tables option walkers (xt_tcpudp and xt_dccp). The vulnerability arises when processing packet options: walkers that increment with i += op[i + 1] ? : 1 can read op[i + 1] past the end of the option area, enabling an out-of-bounds read. Multiple...

CVE-2026-43483

CVE-2026-43483 (Linux kernel, KVM/VMX-SVM) fixes a flaw in SVM AVIC handling where CR8 write interception could remain enabled after AVIC activation. The patch explicitly sets/clears CR8 interception when AVIC is (de)activated to prevent the dangling intercept, which could cause TPR desynchroniza...

CVE-2026-43495

CVE-2026-43495 concerns the Linux kernel net/wwan/t7xx subsystem. The issue arises in t7xx_port_enum_msg_handler, which uses a modem-provided port_count to loop over port_msg->data[] without ensuring the message buffer is long enough, enabling a potential slab-out-of-bounds read when port_coun...

CVE-2026-45961

CVE-2026-45961 in the Linux kernel’s GFS2 filesystem is fixed: memory leaks occur on gfs2_fill_super() error paths when transitioning to read-write mode. Two leaks are addressed: (1) kernel thread objects (logd, quotad) not destroyed after init_threads() if failure occurs; (2) a quota bitmap buff...

CVE-2026-45962

The CVE affects the Linux kernel ublk driver, where ublk_ctrl_cmd_dump() could access (header *)sqe->cmd before checking IO_URING_F_SQE128, enabling out-of-bounds memory access. The mitigation is to check the SQE128 flag earlier in ublk_ctrl_uring_cmd() and return -EINVAL if not set. Several s...

CVE-2026-45983

In CVE-2026-45983, the Linux kernel NFS server (nfsd) vulnerability stems from idmap lookup upcalls during v4 request decoding: if upcall responses are delayed beyond the time limit, cache_check() postpones the request and it gets dropped, causing NFSD4_SLOT_INUSE to block subsequent SEQUENCE ope...

CVE-2026-46041

CVE-2026-46041 affects the Linux kernel with a fix for sleeping in an atomic context in the hdlc path used by greybus/gb-beagleplay.

CVE-2026-46067

CVE-2026-46067 affects the Linux kernel DAMON core. The issue arises because the code path in mm/damon/core validates the node-datas used by NODE-DATA() relies on damos_quota_goal->nid but does not validate its value, allowing an arbitrary nid to be supplied for node_memcg_{used,free}_bp. This...

CVE-2026-46068

CVE-2026-46068 affects the Linux kernel's crypto nx path: bounce buffers allocated with _get_free_pages() (BOUNCE_BUFFER_ORDER) are freed with free_page() instead of free_pages(), causing memory leaks. The fix uses free_pages() with the matching order in nx842_crypto {alloc,free}_ctx. Affected: L...

CVE-2026-46071

CVE-2026-46071 concerns Linux kernel KVM/nSVM behavior where svm_copy_lbrs() marks VMCB_LBR dirty, and nested_svm_vmexit() copies LBRs to vmcb12; clearing VMCB_LBR dirty bits in vmcb12 was not architecturally defined. The fix moves vmcb_mark_dirty() back to callers and drops it for vmcb12, enabli...

CVE-2026-46078

Summary: CVE-2026-46078 affects the Linux kernel EROFS filesystem, where trailing dirents can trigger an out-of-bounds read due to incorrect nameoff handling. The root cause is that namelen calculations for trailing dirents use strnlen with unchecked nameoffs, allowing underflow when nameoff >...

CVE-2026-46163

CVE-2026-46163 concerns the Linux kernel wifi subsystem (b43legacy) where a firmware-controlled key index in b43legacy_rx() could exceed dev->max_nr_keys, allowing an out-of-bounds read of dev->key[]. The fix makes the bounds check enforcing by dropping frames with invalid indices. Patches ...

CVE-2026-46165

CVE-2026-46165 affects the Linux kernel openvswitch vport code, where a self-deadlock could occur on tunnel port release due to improper ordering between RCU callbacks and RTNL/normally synchronized code paths. The root cause: vports are protected by RCU and must have netdev_put() after the RCU g...

CVE-2026-46169

The CVE-2026-46169 case concerns the Linux kernel HFS Plus (HFS+) filesystem. The root cause is that hfs_brec_read() validates only that entrylength fits a buffer but does not confirm that the on-disk catalog record size matches the expected type, allowing partial reads on corrupted filesystems. ...

CVE-2026-46277

CVE-2026-46277 in the Linux kernel fixes a use-after-free-like condition in mm/zone_device where a device folio can change after calling folio_free(), risking invalid extraction of the pgmap if touched again. The issue arises because a folio may be reallocated by a driver with a different order, ...
