CVE-2026-80598

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.
