CVE-2026-89666

A flaw was found in the kernel. A remote attacker, acting as an NFSv3 client, can send malformed time values during SETATTR or create operations. This can lead to the corruption of on-disk metadata, resulting in incorrect timestamps for files. This issue affects filesystems that support nanosecon...

CVE-2026-89701

A flaw was found in the Linux kernel's Network File System Daemon nfsd. The TIMEDELEGACCESS and TIMEDELEGMODIFY decode paths do not properly validate the nanosecond nseconds value in timestamps. This allows a remote attacker to provide a malformed timestamp, which can then be written to disk,...
