CVE-2026-64386

CVE-2026-64386 : In the Linux kernel SMB client, a replayable error could free the prior response buffer when SMB2_query_info_init() fails before the next send, causing a double-free. The fix resets response bookkeeping before each attempt to prevent stale frees. Affected component is the SMB cli...

CVE-2026-10677 Kernel heap memory leak in `z_vrfy_k_poll()` lets an unprivileged user thread exhaust the kernel resource pool

The CONFIGUSERSPACE syscall verifier zvrfykpoll in kernel/poll.c allocates a kernel-side copy of the user-supplied kpollevent via zthreadmalloc and then validates each event's object handle. Before this fix, validation used KOOPSKSYSCALLOBJ... inline inside the loop, which kills the calling threa...
