CVE-2024-26865

CVE-2024-26865 involves a use-after-free in the Linux kernel’s RDS TCP path (reqsk_timer_handler) that can occur when a per-netns listener is created, a reqsk is formed, the process exits, and the netns is dismantled before the timer expires. The issue is fixed by a patch (commit 740ea3c4a0b2) wh...
