DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

crypto/krb5, rxrpc: Fix lack of pre-decrypt/pre-verify length checks

Change the krb5 crypto library to provide facilities to precheck the length of the message about to be decrypted or verified.

Fix AF_RXRPC to make use of this to validate DATA packets secured with RxGK.

AnalysisAI

A remote denial-of-service vulnerability in the Linux kernel's AF_RXRPC subsystem allows unauthenticated attackers to crash the system by sending malicious RxGK-secured DATA packets. The flaw stems from missing length checks in the Kerberos 5 crypto library before message decryption or verification. While the CVSS score is 7.5 (High), no active exploitation or public proof-of-concept exists, and EPSS predicts a low exploitation probability (0.17%), suggesting limited immediate real-world risk.
