CVE-2026-9149: Opensuse Libsolv

Medium severity, CVSS 6.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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).
