Nilfs Utils
Monthly
NILFS utilities (nilfs-utils) through version 2.3.0 crash when processing crafted NILFS2 filesystem images due to missing bounds validation on the s_log_block_size superblock field before performing bit-shift operations. Tools including nilfs-tune and dumpseg are affected: an attacker who can persuade a user to process a malicious image can trigger undefined behavior - either oversized shift operations or out-of-memory conditions - resulting in a denial of service via tool crash. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
