# CVE-2026-80598

> 7.8 HIGH

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

ntfs3: fix out-of-bounds read in decompress_lznt

decompress_lznt() does not validate array index bounds before accessing
the decompression table. A corrupted NTFS3 image with invalid compressed
data can trigger an out-of-bounds read.

Add index bounds checking to prevent the OOB access.
