High 7.0CVE-2023-6546 Public exploit
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 GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem …
