A race condition flaw, leading to heap-based buffer overflows, was found in the way the Linux kernel’s N_TTY line discipline (LDISC) implementation handled concurrent processing of echo output and TTY write operations originating from user space when the underlying TTY driver was PTY. An unprivileged, local user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
