Heap buffer overflow in libsolv allows local attackers to corrupt memory when a vulnerable application processes a maliciously crafted .solv repository metadata file. The flaw stems from insufficient input validation during decompression of attacker-controlled data, enabling information disclosure, control-flow alteration, or denial of service across multiple Red Hat Enterprise Linux releases and SUSE distributions. SSVC marks exploitation as PoC-level with total technical impact, while EPSS remains very low at 0.01%, indicating limited probability of widespread exploitation despite high severity.
