CVE-2026-120454

MediumCVSS 5.5
Published: Updated: Translated: NVD NIST

Summary

The Sleuth Kit through 4.15.0 contains a NULL pointer dereference vulnerability in decmpfs_decompress_lzvn_attr() that allows attackers to crash the tool by supplying a crafted HFS+ image. A huge uncompressed_size in an LZVN inline com.apple.decmpfs attribute causes allocation failure and a write through NULL.

Risk Assessment

Denial of service is possible for forensic tools processing malicious HFS+ images. The risk affects environments analyzing untrusted images.

Recommendation

Update The Sleuth Kit to a version containing the fix. Until then, avoid analyzing untrusted HFS+ images or isolate analysis processes.

Original NVD description (English source)

The Sleuth Kit through 4.15.0 contains a NULL pointer dereference vulnerability in decmpfs_decompress_lzvn_attr() that allows attackers to crash the tool by supplying a crafted HFS+ image. Attackers can set a huge uncompressed_size in an LZVN inline com.apple.decmpfs attribute so allocation fails and the decoder writes through NULL, causing denial of service.
