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. (CVE-2020-25212)
Impact
The specified products contain the affected code. However, F5 identifies this vulnerability with the not vulnerable status because the attacker cannot exploit the code in default, standard, or recommended configurations.
