CVE-2026-22780
Description
A flaw was found in Rizin, a UNIX-like reverse engineering framework. This heap overflow vulnerability can be exploited when a user parses a malicious mach0 file that contains specially crafted entries for the dynamic linker (dyld) chained segments. Successful exploitation could allow a remote attacker to achieve arbitrary code execution or cause a denial of service.
Statement
Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.
Mitigation
To mitigate this issue, avoid processing untrusted mach0 files with Rizin. Exercise caution when handling files from unknown or suspicious sources, as parsing such files could trigger the vulnerability.
Understanding the Weakness (CWE)
Integrity,Availability,Confidentiality
Technical Impact: DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands; Read Memory; Modify Memory
If the incorrect calculation is used in the context of memory allocation, then the software may create a buffer that is smaller or larger than expected. If the allocated buffer is smaller than expected, this could lead to an out-of-bounds read or write (CWE-119), possibly causing a crash, allowing arbitrary code execution, or exposing sensitive data.
