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,...

CVE-2026-89697

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When setting file attributes using nfsdprocsetattr, a specific code path BOTHTIMESET branch prematurely verifies file handles. This bypasses a critical write verification step fhwantwrite, allowing file attribute changes to...

CVE-2026-54174

CVE-2026-54174 affects melange (Chainguard's declarative APK package builder), specifically the Apko component (chainguard.dev/apko). Prior to Apko 1.2.9 (corresponding to melange 0.50.4), the tool verified the control section hash (.PKGINFO etc.) against the signed APKINDEX but never verified th...

CVE-2026-89480

A flaw was found in the NVMe-TCP implementation of the Linux kernel. This vulnerability occurs when the system completes a data read request even if the connected controller transfers fewer bytes than expected. As a result, the user application receives a mix of legitimate and stale data,...
