Description

A flaw was found in the Linux kernel's rxrpc subsystem, specifically in the rxkad crypto unalignment handling. A remote attacker could send a specially crafted packet with a misaligned crypto length. This improper handling could lead to system instability or a denial of service (DoS) due to incorrect decryption error handling and the removal of a remotely triggerable warning mechanism.
