uutils coreutils has a Time-of-Check to Time-of-Use (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...

uutils coreutils has an Unchecked Return Value Issue

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directorie...

CVE-2026-31456

A flaw was found in the Linux kernel. A race condition in the memory management subsystem, specifically when handling page table entries, can be triggered by a local user. This can lead to a kernel bug, causing a system crash and resulting in a denial of service...

CVE-2026-35374

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the split utility of uutils coreutils. The program attempts to prevent data loss by checking for identity between input and output files using their file paths before initiating the split operation. However, the utility subsequently...

CVE-2026-35357

The cp utility in uutils coreutils is vulnerable to an information disclosure race condition. Destination files are initially created with umask-derived permissions e.g., 0644 before being restricted to their final mode e.g., 0600 later in the process. A local attacker can race to open the file...

Race Condition

Overview Affected versions of this package are vulnerable to Race Condition in the heartbeat process. An attacker can cause the server to crash or become unresponsive by triggering concurrent session heartbeat and closure operations, leading to a panic or deadlock due to improper synchronization...

CVE-2026-35376 uutils coreutils chcon Security Bypass and Mandatory Access Control (MAC) Inconsistency via TOCTOU Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the chcon utility of uutils coreutils during recursive operations. The implementation resolves recursive targets using a fresh path lookup via ftsaccpath rather than binding the traversal and label application to the specific directory...

CVE-2026-35360

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 OTRUNC. An attacker can exploit this window to create ...
