kernel: NFSv4: include MAY_WRITE in open permission mask for O_TRUNC

A flaw was found in the Linux kernel's NFSv4 implementation. A local user could exploit a vulnerability where opening a file with OTRUNC truncate and ORDONLY read-only flags would bypass the necessary write permission checks. This oversight allows an attacker to truncate a file without having...

CVE-2026-64846

Nix is a package manager for Linux and other Unix systems. Prior to 2.35.0, a malicious derivation executed with the recursive-nix experimental feature can exploit a time-of-check/time-of-use race involving final symlink handling in the LocalStore restore path. The race can cause writeFile to...

CVE-2026-64846 Nix: Arbitrary file truncation outside the sandbox with recursive-nix experimental feature

Nix is a package manager for Linux and other Unix systems. Prior to 2.35.0, a malicious derivation executed with the recursive-nix experimental feature can exploit a time-of-check/time-of-use race involving final symlink handling in the LocalStore restore path. The race can cause writeFile to...

CVE-2026-64846

Nix versions prior to 2.35.0 contain a TOCTOU race in the LocalStore restore path: writeFile opens a path with O_TRUNC instead of enforcing FinalSymlink::DontFollow, allowing a malicious derivation (with recursive-nix enabled) to create or truncate an empty file outside the build sandbox with dae...

CVE-2026-49428

Certain system calls, such open2 with the OTRUNC flag set, and fspacectl2, could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug to access freed kernel...

CVE-2026-19730

The 'podman quadlet install --replace' command opens the existing destination file with OCREATE|OWRONLY but omits OTRUNC. When the initial reflink copy attempt fails common on non-reflink-capable filesystems including many RHEL default XFS configurations, the fallback in ReflinkOrCopy uses io.Cop...
