CyberRota Analysis
AI-GeneratedThe vulnerability in the iso9660 driver of libfsimage allows an attacker to manipulate on-disk fields, leading to potential underflows in the calculation of the System Use area. This could result in unexpected behavior or crashes when processing ISO images, impacting the stability and security of systems utilizing this driver. Organizations using libfsimage or handling ISO files should prioritize addressing 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.
