CVE-2026-72321

CVE-2026-72321 affects the Linux kernel’s IGMP timer handling (ipv4: igmp). The root cause is a memory leak when deleting or stopping timers in igmp_mod_timer() and igmp_stop_timer(): refcount_dec(&im->refcnt) can drop the group entry im to zero on an RC reader path, leaving the im object leak...

CVE-2026-72319

The CVE-2026-72319 entry describes a Linux kernel vulnerability in IPVS where inner IP headers in ICMP errors must be kept within skb headroom after removing outer headers (pskb_pull). The root cause involves ensuring the inner headers remain present for functions such as ipv4_update_pmtu(), icmp...

CVE-2026-72320

CVE-2026-72320 concerns the Linux kernel netfilter implementation for nft_lookup. The issue arises in how inverted lookups (NFT_LOOKUP_F_INV) interact with the catchall element in interval sets, potentially causing an incorrect verdict. The documented fix folds the catchall lookup into ext before...

CVE-2026-72318

CVE-2026-72318 affects the Linux kernel CIFS/SMB path handling. The flaw arises in parse_dfs_referrals(), where string offsets in DFS referrals are not validated against the received buffer, allowing crafted referrals to cause pointers to read outside the buffer. This can lead to out-of-bounds re...

CVE-2026-72317

In the Linux kernel SUNRPC TLS connect path, a use-after-free occurs because upper rpc_clnt is not pinned across the delayed TLS connect_worker. The TLS handshake worker xs_tcp_tls_setup_socket() reads saved fields from a freed rpc_clnt when a handshake fails, leading to a refcount underflow. The...
