Libsolv: heap buffer overflow in libsolv repo_add_solv via negative maxsize from crafted .solv file
CVE-2026-9149 is fixed in 17 products on 1 platform, first by DEBIAN-CVE-2026-9149, released May 21, 2026. It is not reported as exploited. Patch Radar priority: High.
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).
