UBUNTU-CVE-2026-89697

In the Linux kernel, the following vulnerability has been resolved: nfsd: add fhwantwrite for early-verified SETATTR in nfsdprocsetattr The BOTHTIMESET branch calls fhverify early so setattrprepare can inspect the dentry. This causes nfsdsetattr to skip fhwantwrite, so notifychange runs without a...
