High [CVE-2023-6546] gsm multiplexing race condition leads to privilege escalation
CVE-2023-6546Source published Source updated
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux.
