GHSA-H848-FW25-HP2W

Vulnerability from github – Published: 2026-04-06 15:31 – Updated: 2026-04-06 21:31
VLAI
Details

A double free vulnerability exists in librz/bin/format/le/le.c in the function le_load_fixup_record(). When processing malformed or circular LE fixup chains, relocation entries may be freed multiple times during error handling. A specially crafted LE binary can trigger heap corruption and cause the application to crash, resulting in a denial-of-service condition. An attacker with a crafted binary could cause a denial of service when the tool is integrated on a service pipeline.

Mitigation
Architecture and Design

Choose a language that provides automatic memory management.

Mitigation
Implementation

Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.

Mitigation
Implementation

Use a static analysis tool to find double free instances.
