CyberRota Analysis
AI-GeneratedThe iso9660 driver in libfsimage is vulnerable due to improper validation of lengths derived from attacker-controlled fields, specifically in the directory loop. This flaw could lead to potential denial-of-service conditions or arbitrary code execution, depending on the exploit. Organizations utilizing libfsimage for handling ISO images should prioritize patching this vulnerability to mitigate risks associated with untrusted input.
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.
