CVE-2026-46137

CVE-2026-46137 affects the Linux kernel MPTCP implementation. The mptcp_pm_add_timer() helper runs as a timer callback in softirq context and can race with socket state unless the socket lock is held with bh_lock_sock(). The mitigation is to hold the lock and retry if the socket is in use, mirror...

CVE-2026-46104

Linux kernel CVE-2026-46104 affects SELinux socket permission helpers. The vulnerability arises because sock_has_perm() and nlmsg_sock_has_extended_perms() dereference sk->sk_security directly, assuming the SELinux socket blob is at offset zero. In stacked LSM configurations this assumption fa...

kernel: can: raw: fix ro->uniq use-after-free in raw_rcv()

A flaw was found in the Linux kernel's Controller Area Network CAN raw socket implementation. A use-after-free vulnerability can occur due to a timing window during the unregistration of CAN receive filters, allowing a freed memory region to be accessed. This could lead to system instability or a...
