Summary
The libsolv packages provide a library for resolving package dependencies using a satisfiability algorithm.
Security Fix(es):
* libsolv: Stack-based buffer overflow in libsolv's Debian metadata parser when handling SHA384/SHA512 checksums (CVE-2026-9150)
* libsolv: Heap buffer overflow in libsolv repo_add_solv via negative maxsize from crafted .solv file (CVE-2026-9149)
* libsolv: Heap buffer overflow in libsolv repopagestore via unchecked decompression of malicious .solv page data (CVE-2026-48864)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Vulnerabilities 3
-
High 7.8
Libsolv: heap buffer overflow in libsolv repopagestore via unchecked decompression of malicious .solv page data
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when proc…

Libsolv: heap buffer overflow in libsolv repo_add_solv via negative maxsize from crafted .solv file
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 subsequen…

Libsolv: stack-based buffer overflow in libsolv's debian metadata parser when handling sha384/sha512 checksums
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 checksu…
