Amendment

The SLES security team deemed this advisory irrelevant for SLES:15.1.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gfs2-kmp-rt package and not the gfs2-kmp-rt package as distributed by SLES.

A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452.
