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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
