CVE-2023-53805

CVE-2023-53805 is a Linux kernel issue affecting the TTY GSM driver (tty/n_gsm). The vulnerability arises from a use-after-free in gsm_cleanup_mux() caused by an improperly cleaned gsm->dlci pointer after gsm_dlci_release, leaving a dangling pointer and freeing/accessing gsm->dlci[0] in sub...

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...
