In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: fix integer overflow in bpf msg pop data bounds check start and len are u32, so u64 last = start + len; evaluates start + len in 32-bit and wraps before storing it in last. The bounds check if start = offset + l ||...
CVE-2026-68284
A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the tcpbpfsendmsg function within the BPF Berkeley Packet Filter and sockmap components. This flaw occurs when two threads attempt to send data on the same socket concurrently, leading to an incorrect memory...
CVE-2026-68386
A flaw was found in the Linux kernel. A local attacker with BPF program capabilities could exploit a vulnerability in the BPF sockmap feature. This occurs when a BPF program increments the reference count of an unbound UDP socket, and the socket is subsequently bound. This sequence of events caus...
CVE-2026-68386
In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Reject unhashed UDP sockets on sockmap update UDP sockets get SOCKRCUFREE set when auto-bound. This means skisrefcountedunbound = true, while skisrefcountedbound = false. Because sockmap accepts unbound UDP sockets,...

CVE-2026-68284
CVE-2026-68284 affects the Linux kernel BPF/sockmap path. The bug is a use-after-free in tcp_bpf_sendmsg() when two threads send on the same socket: msg_tx is compared to psock->cork while cork may have been freed, leading to freeing a stale cork. A fix ensures tmp cork is checked directly, pr...
