Affected: Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Telecommunications Update Service, Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions, Red Hat Enterprise Linux 8.6 Extended Update Support, Red Hat Enterprise Linux 8.8 Extended Update Support, Red Hat Enterprise Linux 9, Red Hat Enterprise Linux 9.0 Extended Update Support, Red Hat Enterprise Linux 9.2 Extended Update Support and 4 more

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. This could allow a local unprivileged user to escalate their privileges on the system.
