CVE-2026-68387

The CVE-2026-68387 defect affects the Linux kernel CAN raw socket path. A change to store flags in a single bitfield (struct raw_sock) introduced a read-modify-write window during raw_setsockopt() flag updates, enabling concurrent access races. The fix adds a locking wrapper around flag manipulat...

CVE-2026-68386 bpf, sockmap: Reject unhashed UDP sockets on sockmap update

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-2026-68386

The CVE concerns the Linux kernel’s BPF sockmap path. It describes a vulnerability where unhashed UDP sockets accepted by sockmap can have their refcount incremented via a BPF lookup, and if the socket becomes bound, the subsequent bpf_sk_release() may skip decreasing the refcount, leading to a m...
