An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.
