CVE-2024-50036

CVE-2024-50036 is a Linux kernel vulnerability where dst_entries_add() uses per-CPU data that can be freed during netns dismantle, making dst_entries_destroy() race with dst_release() and potentially causing a use-after-free. The issue arises because the count of dsts must be decremented earlier,...
