CVE-2024-46858

CVE-2024-46858 in the Linux kernel fixes a local UAF race in mptcp_pm_del_add_timer. Two paths can access mptcp_pm_del_add_timer concurrently (CPU1 in PM code path vs CPU2 in netlink/ip stack path), leading to use-after-free when a timer entry is freed after leaving the critical region. The patch...
