CVE-2026-43458

The CVE affects the Linux kernel’s caif_serial line discipline. A use-after-free (KASAN slab UAF) could be triggered in pty_write_room() when the caif_serial TX path invokes tty_write_room(), accessing tty->link->port. Root cause: improper management of the tty->link reference during ldi...
