CVE-2026-89714 NFS: fix delegation_hash_table leak when nfs4_server_common_setup() fails

In the Linux kernel, the following vulnerability has been resolved: NFS: fix delegationhashtable leak when nfs4servercommonsetup fails nfs4servercommonsetup allocates server-delegationhashtable first, but server-destroy - the only path that frees the table via nfs4destroyserver - is not assigned...

CVE-2026-89714

This Linux kernel vulnerability affects the NFSv4 client subsystem. The root cause is a memory leak of server->delegation_hash_table (4 KiB per attempt with the default delegation watermark) when nfs4_server_common_setup() fails at an intermediate step (is_ds_only_client(), nfs4_init_session()...

kernel: rhashtable: clear stale iter->p on table restart

A flaw was found in the Linux kernel. This vulnerability, known as a use-after-free, occurs in the rhashtable component when the system improperly handles hash table restarts. An attacker could potentially exploit this by causing the system to access memory that has already been released, which m...

CVE-2026-71219 Gfs2-utils: gfs2-utils: stack overflow via alloca(1<<di_depth) in hash table traversal

A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca with an exponentially-derived size from the untrusted on-disk didepth field without bounds validation. A crafted GFS2 filesystem image with a large didepth value causes stack exhaustion...

ALPINE-CVE-2026-40017

An attacker that can send mail to a user can craft a message header whose values are chosen to collide in an internal hash table, which makes the IMAP THREAD command consume CPU disproportionate to the size of the message. This is a separate issue from CVE-2026-40014 and is not addressed by that...

CVE-2026-80714

CVE-2026-80714 is a use-after-free in the Linux kernel's IPVS (IP Virtual Server) subsystem. The root cause is that ip_vs_bind_dest() propagates the IP_VS_CONN_F_ONE_PACKET flag from a destination to a synced connection that is already hashed. During expiry, the kernel then treats the synced conn...
