CVE-2026-9150

A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.

This Moderate impact flaw in libsolv's Debian metadata parser can lead to a denial of service due to a stack-based buffer overflow. Exploitation requires a victim to process specially crafted, untrusted Debian repository metadata containing malicious SHA384 or SHA512 checksums. While memory corruption occurs, reliable system compromise has not been demonstrated, and the vulnerability is not typically exposed in default Red Hat product configurations.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, ensure that libsolv only processes trusted and cryptographically signed Debian repository metadata. Avoid ingesting or processing Packages files from untrusted or unverified sources.
