In the Linux kernel, the following vulnerability has been resolved: kcm: Fixed error handling for SOCKDGRAM in kcmsendmsg. Syzkaller identified a memory leak in kcmsendmsg, and the commit c821a88bd720 "kcm: Fix memory leak in the error path of kcmsendmsg" suppressed this issue by updating...

Linux Distros Unpatched Vulnerability : CVE-2026-72124

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - can: isotp: serialize TX state transitions under so-rxlock The TX state machine so-tx.state is driven from three contexts: sendmsg claiming and progressing a...

CVE-2026-12234

The CVE affects Zephyr’s userspace networking verification on zsock_sendmsg/zsock_recvmsg. The issue is a TOCTOU double-fetch: the verifier snapshots struct net_msghdr, yet later re-reads the live user memory to bound the loop, allowing a race where msg_iovlen can be inflated after the shadow buf...
