CVE-2026-89709

CVE-2026-89709 affects the Linux kernel's lockd and nfsd subsystems. The nlmsvc_ops pointer is published and cleared with plain stores while lockd dereferences it unguarded from dispatch sites in fs/lockd/svcsubs.c. After rmmod nfsd, a stale load produces either a NULL pointer dereference or a mo...

CVE-2026-80753

CVE-2026-80753 affects the Linux kernel's ovpn module . Work items whose callbacks execute module text ran on the global system workqueues, meaning module exit had no driver-owned drain point to guarantee callbacks had returned before the module text could be freed. Specifically, a worker could d...

CVE-2026-74660

CVE-2026-74660 is a use-after-free in the Linux kernel's netfilter: ebt_nflog component. The ebt_nflog module passes an explicit ULOG log type to nf_log_packet() without holding a reference on the nfnetlink_log module, unlike the xt_NFLOG and nft_log frontends. This allows an ebtables nflog rule ...
