CVE-2026-22780

Status: AnalyzedMedium (6.1)—

Rizin is a UNIX-like reverse engineering framework and command-line toolset. Prior to 0.8.2, a heap overflow can be exploited when a malicious mach0 file, having bogus entries for the dyld chained segments, is parsed by rizin. This vulnerability is fixed in 0.8.2.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
