CVE-2026-10677

The CVE concerns Zephyr’s CONFIG_USERSPACE verifier z_vrfy_k_poll() in kernel/poll.c, where a user-supplied k_poll_event[] is copied to kernel space and validated. Previously, an inline K_OOPS(K_SYSCALL_OBJ(...)) inside the loop could leak the allocation when a forged object handle was encountere...

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...

GHSA-4XJF-493Q-98P3 Gitea SSH Key Parser Denial of Service

Gitea's SSH key ingestion endpoint accepts keys in RFC 4716 SSH2 format and normalises them before storage. The normalisation function contains an ON² string concatenation loop with no input size limit, meaning a single malicious key submission can force the server to perform an amount of work th...
