Summaryinfo

A vulnerability was found in Uutils coreutils. It has been rated as problematic. Affected is an unknown function. Performing a manipulation results in improper handling of unicode encoding. This vulnerability is known as CVE-2026-35373. Attacking locally is a requirement. No exploit is available.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Uutils coreutils (version unknown). This affects an unknown function. The manipulation with an unknown input leads to a improper handling of unicode encoding vulnerability. CWE is classifying the issue as CWE-176. The product does not properly handle when an input contains Unicode encoding. This is going to have an impact on availability. The summary by CVE is:

A logic error in the ln utility of uutils coreutils causes the program to reject source paths containing non-UTF-8 filename bytes when using target-directory forms (e.g., ln SOURCE... DIRECTORY). While GNU ln treats filenames as raw bytes and creates the links correctly, the uutils implementation enforces UTF-8 encoding, resulting in a failure to stat the file and a non-zero exit code. In environments where automated scripts or system tasks process valid but non-UTF-8 filenames common on Unix filesystems, this divergence causes the utility to fail, leading to a local denial of service for those specific operations.

The weakness was published by Zellic. It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-35373 since 04/02/2026. The exploitability is told to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
