CVE-2026-64040

In the Linux kernel, the following vulnerability has been resolved: cachefiles: Fix error return when vfsmkdir fails When vfsmkdir fails, the error code is not extracted from the returned error pointer. This causes mkdirerror to be reached with ret=0, which leads to returning ERRPTR0 NULL instead...

CVE-2026-64040

CVE-2026-64040 affects the Linux kernel’s cachefiles path. The root cause is that when vfs_mkdir() fails, the error code was not extracted from the error pointer, causing mkdir_error to be reached with ret=0 and returning ERR_PTR(0) (NULL) instead of a proper error pointer. The public description...

mkdir: -m exposes directory with umask perms before chmod race window...

GHSA-MJ6P-44CH-CQ69 mkdir: -m exposes directory with umask perms before chmod (race window)

The mkdir utility in uutils coreutils incorrectly applies permissions when using the -m flag by creating a directory with umask-derived permissions typically 0755 before subsequently changing them to the requested mode via a separate chmod system call. In multi-user environments, this introduces ...

Flight is an extensible micro-framework for PHP. Prior to 3.18.1, the make:controller CLI command calls mkdir..., recursive: true on a path built from the user-supplied controller name, before Nette's class-name validation runs. The class-file write is correctly rejected by Nette when the name...

SUSE CVE-2024-4030

On Windows a directory returned by tempfile.mkdtemp would not always have permissions set to restrict reading and writing to the temporary directory by other users, instead usually inheriting the correct permissions from the default location. Alternate configurations or users without a profile...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ovl: fixed the warning in ovlcreatereal Syzbot triggered the following warning in ovlworkdircreate - ovlcreatereal: if !err && WARNON!newdentry-d inode The reason is that the cgroup2 filesystem returns from mkdir without...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fs/9p: Fixed the issue of NULL pointer dereferencing when using mkdir. When a 9p tree was mounted with the posixacl option, the parent directory had a default ACL set for its subdirectories. For example: setfacl -m...

goshs is a SimpleHTTPServer written in Go. From 2.0.0-beta.4 to 2.0.0-beta.5, goshs contains a cross-site request forgery issue in its state-changing HTTP GET routes. An external attacker can cause an already authenticated browser to trigger destructive actions such as ?delete and ?mkdir because...

Summary The make:controller CLI command calls mkdir..., recursive: true on a path built from the user-supplied controller name, before Nette's class-name validation runs. The class-file write is correctly rejected by Nette when the name contains /, but the recursive directory creation side effect...

apko dirFS has a symlink-following path traversal that allows multiple entry points to escape the build root

A crafted .apk could install a TypeSymlink tar entry whose target pointed outside the build root, and a subsequent directory-creation or file-write entry in the same or later archive could traverse that symlink to reach host paths the build user could write to. The root cause was the sanitizePath...
