CVE-2026-5121
Libarchive: libarchive: arbitrary code execution via integer overflow in iso9660 image processing
Overview
Description
A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system.

New CVE Received by [email protected]
Mar. 30, 2026
Action Type Old Value New Value Added Description A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system. Added Reference https://access.redhat.com/security/cve/CVE-2026-5121 Added Reference https://github.com/libarchive/libarchive/pull/2934
EPSS is a daily estimate of the probability of exploitation activity
being observed over the next 30 days. Following chart shows the EPSS
score history of the vulnerability.
