CVE-2026-9149
PUBLISHED
CVSS 6.5 MEDIUM
Reported by redhat · Published May 20, 2026
A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).
