CVE-2026-35341
Description
A flaw was found in uutils coreutils mkfifo. This vulnerability allows a local user to inadvertently change the permissions of an existing file when attempting to create a named pipe (FIFO) at the same location. The mkfifo utility, instead of failing, proceeds to set the existing file's permissions to a default, often less restrictive, mode. This unauthorized modification could expose sensitive data, such as SSH private keys, to other users on the system.
