CVE-2026-12234 TOCTOU double-fetch in `zsock_sendmsg`/`recvmsg` userspace verifiers allows kernel-heap out-of-bounds write

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-2026-5066: Out-of-bounds Write

A potential out-of-bounds write/read exists in the TLS socket connect path of the network sockets subsystem subsys/net/lib/sockets/socketstls.c. When the TLS session cache is enabled, tlssessionstore and tlssessionrestore memcpy the caller-supplied address into a fixed-size buffer using the...

The vulnerability of the Windows Ancillary Function Driver for WinSock operating system allows attackers to increase their privileges.

The vulnerability of the Windows Ancillary Function Driver for WinSock operating system is related to the possibility of using memory after it is freed. Exploiting this vulnerability can allow an attacker to increase their privileges...
