Linux · Linux Kernel · CVE-2022-1462
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue is related to an out-of-bounds read flaw in the Linux kernel's TeleTYpe subsystem. It occurs due to a race condition triggered by a user using ioctls `TIOCSPTLCK`, `TIOCGPTPEER`, `TIOCSTI`, and `TCXONC`, resulting in memory leakage in the `flush to ldisc` function. This allows a local user to crash the system or read unauthorized random data from memory. The flaw can be exploited to gain access to confidential data and cause a denial of service.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
