Linux kernel TTY driver Privilege Escalation
The vulnerability of the gsmdlciconfig function in the TTY driver drivers/tty/ngsm.c of the Linux kernel is related to the reallocation of previously freed memory due to concurrent access to resources. Exploiting this vulnerability can allow an attacker to increase their privileges...
kernel: GSM multiplexing race condition leads to privilege escalation
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOCSETCONF 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 gsmdlci while restarting th...
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...
