Summary
libsolv security update
Details

A free package dependency solver using a satisfiability algorithm. The library is based on two major, but independent, blocks:

Security Fix(es):

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).(CVE-2026-9149)

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.(CVE-2026-9150)
