CVE-2026-12234

The userspace syscall verifiers zvrfyzsocksendmsg and zvrfyzsockrecvmsg in subsys/net/lib/sockets/sockets.c snapshot the caller-supplied struct netmsghdr into a kernel-side copy with kusermodefromcopy, but then re-read the still-live user struct for subsequent decisions. The kernel iovec shadow...

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...

PT-2026-80506

GNU gzip contains a vulnerability in the gzexe utility related to insecure temporary file handling. When the mktemp utility is not available in the user’s PATH, gzexe falls back to constructing a temporary file path based solely on the process ID PID. This predictable filename is created without...

CVE-2026-68107

A flaw was found in the Linux kernel. Specifically, within the drm/amdgpu/vcn4 component, a time-of-check to time-of-use TOCTOU vulnerability exists. This occurs because the system re-reads the IB parameter length instead of reusing an already obtained value. This could allow a local attacker to...
