CyberRota Analysis
AI-GeneratedThe vulnerability affects the libfsimage's iso9660 driver, specifically in its handling of Rock Ridge extension records, where it improperly validates lengths derived from attacker-controlled on-disk fields. This could lead to potential denial-of-service conditions or arbitrary code execution due to improper memory handling. Organizations utilizing systems that rely on this driver should prioritize patching to mitigate associated risks.
Original NVD Description
[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] The directory and Rock Ridge / SUSP walk in libfsimage's iso9660 driver derives several lengths directly from attacker-controlled on-disk fields without validating them: * The directory loop itself assumes a good record length. This is CVE-2026-42494. * The calculation of the System Use area may underflow. This is CVE-2026-42495. * The Rock Ridge extension loop assumes a good (inner) record length. This is CVE-2026-62423. * The Rock Ridge NM record processing assumes a good entry length. This is CVE-2026-62424. * The Rock Ridge CE record processing assumes a good size and offset. This is CVE-2026-62425.
