Detailed vulnerability description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when processing untrusted input in the Linux kernel’s Transport Layer Security functionality in the way a user calls a function splice with a ktls socket as the destination. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
