CVE-2026-15924

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...
