CVE-2026-35360

The CVE-2026-35360 entry concerns the touch utility in uutils coreutils. A TOCTOU race occurs during file creation: when touch detects a missing path, it later calls File::create(), which uses O_TRUNC, allowing a local attacker to create a file or swap a symlink at the target path. This can cause...

CVE-2026-35359 uutils coreutils cp Information Disclosure via Time-of-Check to Time-of-Use Symlink Swap

A Time-of-Check to Time-of-Use TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass no-dereference intent. The utility checks if a source path is a symbolic link using path-based metadata but subsequently opens it without the ONOFOLLOW flag. An attacker with...

CVE-2026-35359

A Time-of-Check to Time-of-Use TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass no-dereference intent. The utility checks if a source path is a symbolic link using path-based metadata but subsequently opens it without the ONOFOLLOW flag. An attacker with...

CVE-2026-35359

The CVE-2026-35359 entry describes a TOCTOU flaw in the cp utility of the uutils coreutils project. The cp command checks whether the source path is a symlink using metadata, then opens the path without O_NOFOLLOW, allowing a concurrent writer to swap a regular file for a symlink during the windo...

CVE-2026-35355 uutils coreutils install Arbitrary File Overwrite via Symlink TOCTOU Race

The install utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file installation. The implementation unlinks an existing destination file and then recreates it using a path-based operation without the OEXCL flag. A local attacker can exploit t...

CVE-2026-35352 uutils coreutils mkfifo Privilege Escalation via TOCTOU Race Condition

A Time-of-Check to Time-of-Use TOCTOU race condition exists in the mkfifo utility of uutils coreutils. The utility creates a FIFO and then performs a path-based chmod to set permissions. A local attacker with write access to the parent directory can swap the newly created FIFO for a symbolic link...

CVE-2026-35352

A Time-of-Check to Time-of-Use TOCTOU race condition exists in the mkfifo utility of uutils coreutils. The utility creates a FIFO and then performs a path-based chmod to set permissions.

CVE-2026-35352

CVE-2026-35352 affects the mkfifo utility in uutils coreutils. A TOCTOU race exists: the tool creates a FIFO and then performs a path-based chmod. A local attacker with write access to the parent directory can replace the newly created FIFO with a symbolic link between the two operations, causing...

CVE-2026-31467

In the Linux kernel, the following vulnerability has been resolved: erofs: add GFPNOIO in the bio completion if needed The bio completion path in the process context e.g. dm-verity will directly call into decompression rather than trigger another workqueue context for minimal scheduling latencies...

PT-2026-34496

The touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create, which internally uses O TRUNC. An attacker can exploit this window to create...
