Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1

Description A flaw in the rxrpc component allows RESPONSE packets to enter a partially decrypted state if a temporary failure occurs during processing. These packets may then be requeued for a retry, leading to incorrect re-decryption. Similarly, an error during the generation of a RESPONSE may cause an incoming CHALLENGE packet to be handled incorrectly.

Recommendations Update to kernel-devel-7.0.11-1.1 for openSUSE Tumbleweed. At the moment, there is no information about a newer version that contains a fix for this vulnerability for the Linux kernel.
