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...

gitpython: GitPython: Arbitrary code execution via command injection due to unguarded Git options

A flaw was found in GitPython where it fails to properly sanitize dangerous Git options. This vulnerability allows an attacker to inject arbitrary commands when using functions like Repo.archive and git.lsremote, potentially leading to arbitrary code execution. Additionally, functions such as...

CVE-2026-74596

A flaw was found in the Linux kernel's fsverity subsystem. The vulnerability is due to the removal of a check in the setattrprepare function, which previously verified if fs-verity was enabled. This change allows fsverity files to be truncated even when the fs-verity feature is not active on the...

CVE-2026-74592

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA. When a file is truncated, the system's integrity policy hooks are not properly instantiated, preventing the action cache flags from being reset. This oversight means that after truncation, the file is not re-collected,...

CVE-2026-74592

This vulnerability affects the Linux kernel's IMA (Integrity Measurement Architecture) subsystem. The root cause is that the file_truncate and path_truncate LSM hooks were not instantiated, meaning the IMA_DONE_MASK action cache flags were not reset when a file was truncated. As a result, after t...
