CVE-2026-15924 Use-after-free / double-free from unsynchronized concurrent access to the TLS client session cache in Zephyr sockets

Zephyr's TLS socket layer in subsys/net/lib/sockets/socketstls.c keeps a single process-global array, clientcache, of cached client sessions that is shared by every TLS socket context. The functions that mutate and read it — tlssessionsave, tlssessionget, tlssessioncachereset, and the settings...

CVE-2026-15924

Zephyr RTOS TLS socket layer contains a use-after-free and double-free vulnerability in the process-global client_cache array shared across all TLS socket contexts. The root cause is that the per-socket mutex (ctx->lock) provides no mutual exclusion between different sockets concurrently acces...

In the Linux kernel, the following vulnerability has been resolved: net/smc: stop killed, freed and outofsync sharing a byte The three connection state flags are single-bit bitfields, so they occupy one byte of struct smcconnection and every store to one is a read-modify-write of the other two: u...

CVE-2026-89712

A use-after-free race condition in the Linux kernel's NFSD component affects nfsd4_ssc_expire_umount(). When this function drops nfsd_ssc_lock to release a source vfsmount, a concurrent NFS RPC thread can free a list entry that the iteration macro has cached as its next pointer, causing a subsequ...

CVE-2026-89689

CVE-2026-89689 is a use-after-free vulnerability in the Linux kernel's NFS daemon (nfsd) , specifically in nfsd4_sequence(). When the session shrinker reduces the number of active slots, free_session_slots() may free a slot still in use by the current request or a concurrent thread, because seq-&...

CVE-2026-89099

A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this...
