CVE-2026-9150
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 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.
Fixes and workarounds
Workaround
To mitigate this issue, ensure that libsolv only processes trusted and cryptographically signed Debian repository metadata. Avoid ingesting or processing `Packages` files from untrusted or unverified sources.
