Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: tcpbpf: The return value of tcpbpfsendmsg was corrected. When we use the cork mechanism in psock-cork, the last message triggers flushing, resulting in sending a skmsg that is larger than the current message size. In this case, i...

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...
