The root cause is that user-direct...

CVE-2026-46164

CVE-2026-46164 affects the Linux kernel's btrfs subsystem. The vulnerability is a double-free in create_space_info_sub_group() when kobject_init_and_add() fails, causing the sub_group to be freed twice as the error path unwinds. The call chain is: create_space_info_sub_group() → btrfs_sysfs_add_s...

CVE-2026-46169

The CVE-2026-46169 case concerns the Linux kernel HFS Plus (HFS+) filesystem.

CVE-2026-52937

CVE-2026-52937 concerns the Linux kernel where the tap_ioctl() path handling SIOCGIFHWADDR leaks kernel stack contents by copying 16 bytes of an uninitialised sockaddr_storage to userspace. Specifically, netif_get_mac_address() writes only sa_family and dev->addr_len (6 bytes), leaving sa_data...

CVE-2026-53218

CVE-2026-53218 affects the Linux kernel netfilter nft_exthdr path. The root cause is a mismatch in register initialization: nft_exthdr_init() passes priv->len to nft_parse_register_store(), which marks that many bytes as initialized, but when NFT_EXTHDR_F_PRESENT is set the eval paths write on...

CVE-2026-53265

The CVE-2026-53265 entry describes a Linux kernel race in the dm-cache policy SMQ path. A check-then-act race occurs in smq_invalidate_mapping where an e->allocated check was left outside the mq->lock after the destructive section was serialized; two concurrent invalidators can observe allo...
