AI-suggested

Red Hat advises avoiding processing or extracting RPM packages from untrusted sources to reduce exposure. Specifically, do not use rpm2cpio, rpm2archive, or rpm -qlvp on RPM files whose origin and integrity cannot be verified. There is no mention of an official patch or fix in the advisory, so users should follow these usage restrictions until a fix is available or confirmed.

Description

CVE-2026-95520 is a heap-based buffer overflow vulnerability in the rpm package parser used in Red Hat Hardened Images. It occurs when parsing a symlink entry in an untrusted RPM package with a crafted RPMTAG_LONGFILESIZES value that triggers an integer overflow, shrinking a buffer allocation to one byte. This allows attacker-controlled data to be written beyond the allocated buffer. The flaw is exploitable locally via rpm2cpio, rpm2archive, or rpm -qlvp commands on untrusted packages. The vulnerability has a CVSS score of 7.1 and is rated as moderate severity by Red Hat due to the requirement for local user interaction and no network exposure.
