CVE-2024-38598 — Linux kernel (md/raid10) softlockup during resync Technical details from the provided documents indicate that the issue arises in the md bitmap synchronization path for raid10 during lvextend/lvchange --syncaction, leading to a soft lockup (CPU 3) due to a logic error in md_bitma...

CVE-2025-21887

In CVE-2025-21887, the Linux kernel overlayfs (ovl) had a use-after-free in ovl_dentry_remote/ovl_dentry_update_reval caused by calling dput(upper) before upper is no longer safe to use; the fix moves dput(upper) to after its final use in ovl_link_up, preventing the UAF. The issue is addressed in...

CVE-2026-23111

CVE-2026-23111 (Linux kernel) : A bug in netfilter nf_tables nft_map_catchall_activate() inverted the genmask check, causing catchall elements to be processed incorrectly during abort of a DELSET operation. The function skipped inactive elements and processed active ones, leading to a use-after-f...

CVE-2023-52524

CVE-2023-52524 (Linux kernel) affects the net:nfc:llcp subsystem. The issue arises from modifying the device list without holding the required lock, which could allow list corruption as observed by syzbot. The vulnerability is local and requires privileges, with a high impact on confidentiality, ...

CVE-2024-48881

CVE-2024-48881 concerns the Linux kernel’s bcache implementation. The issue was a NULL pointer dereference risk in cache_set_flush() caused by a changed check: the code could access c->root when previous registration failed before c->root was allocated. The patch reverts the IS_ERR check to...

CVE-2024-58093

CVE-2024-58093 affects the Linux kernel’s PCI/ASPM link state handling. The issue arises when removing functions on a bus with a PCIe switch/MFD: freeing the ASPM link state either too late (function 0 removed last) or too early (before all subordinate links are gone), leading to use-after-free o...

CVE-2023-4515

CVE-2023-4515: Linux kernel ksmbd had command payload size checks missing for most commands (except SMB2_OPLOCK_BREAK_HE). An attacker with local access could exploit this to trigger issues due to unchecked request sizes. A fix was committed to validate command payload sizes; the SUSE advisories ...

CVE-2026-23278

CVE-2026-23278 (Linux kernel nf_tables catchall handling) The issue occurs in netfilter nf_tables where, during transaction processing, a map holding catchall elements being removed may require toggling all pending catchall elements, not just the first viable candidate. If the map is also being f...

CVE-2026-23428

CVE-2026-23428 affects the Linux kernel ksmbd component handling SMB2. The root cause is a use-after-free when reusing work->tcon in compound SMB2 requests: after a prior command (e.g., SMB2_TREE_DISCONNECT) sets t_state to TREE_DISCONNECTED and ksmbd_share_config_put() frees share_conf, subse...
