CVE-2026-46214

CVE-2026-46214 relates to the Linux kernel vsock/virtio transport: a backlog count leak occurs when vsock_assign_transport() fails or switches transport, because sk_acceptq_added() is called before transport validation and not removed on error. This can cause sk_acceptq_is_full() to reject new co...

CVE-2026-46213

The CVE-2026-46213 issue affects the Linux kernel HID Apple keyboard driver (appletb-kbd). A use-after-free (UAF) in the inactivity-timer cleanup path during driver tear-down was fixed by reordering teardown: (1) call hid_hw_close()/hid_hw_stop() before backlight cleanup to prevent late callbacks...

CVE-2026-46212

CVE-2026-46212 concerns the Linux kernel’s batman-adv module.
