CVE-2023-52872

The CVE-2023-52872 vulnerability affects the Linux kernel tty/n_gsm subsystem. A race in gsm_cleanup_mux() during the cleanup of GSM DLCIs can spuriously change virtual modem status lines while data/timers are being torn down, risking a kernel panic when resources have already been removed. The f...

CVE-2023-52789

CVE-2023-52789 : In the Linux kernel, the vulnerability affects the tty/vcc path (vcc_probe). The root cause is failure to check the return value of kstrdup(), risking a NULL pointer dereference. The fix adds a check for kstrdup() and returns an error if it fails. This resolves the issue by preve...
