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...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: sock: The protection check for psock vs. ULP needs to be reimplemented. Commit 8a59f9d1e3d4 “sock: Introduce sk-skprot-psockupdateskprot” has moved the inetcskhasulpsk check from skpsockinit to the new tcpbpfupdateproto function....

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Check for any of tcpbpfprots when cloning a listener. A listening socket linked to a sockmap has its skprot overridden. It points to one of the struct proto variants in tcpbpfprots. This variant depends on the...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: bpf, sockmap: Fixed a memory leak in tcpbpfsendmsg when skmsg is full. If tcpbpfsendmsg is running while skmsg is full, and skmsgalloc returns an -ENOMEM error, tcpbpfsendmsg will enter a waitformemory state. If part of the...

CVE-2026-68284

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix cork use-after-free in tcpbpfsendmsg tcpbpfsendmsg keeps msgtx across skstreamwaitmemory, which drops and reacquires the socket lock. Its error path tries to decide whether msgtx names the local temporary messag...

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...
