A null pointer dereference vulnerability (CVE-2026-47143) was found in the Capstone disassembly framework affecting builds compiled with the -DCAPSTONE_X86_REDUCE flag. This flaw can cause applications using the reduced X86 Capstone library to crash when processing specially crafted 3DNow! opcode inputs, resulting in a denial of service (DoS). The vulnerability affects specific Red Hat Hardened Images RPM packages of Capstone version 5.0.8-0.1.hum1. Red Hat has issued an update to address this issue.

Capstone is a disassembly framework. Versions prior to 6.0.0-Alpha8 and 5.0.8 have a NULL pointer dereference in `modRMRequired()` and `decode()` when disassembling 3DNow! opcodes (`0F 0F`) in builds compiled with `-DCAPSTONE_X86_REDUCE`, allowing a remote attacker to crash any application using the reduced X86 Capstone library by supplying a crafted input containing the 4-byte sequence `0F 0F <modrm> <imm8>`. Versions 6.0.0-Alpha8 and 5.0.8 patch the issue. Join the discussion | CVE Database V5 | 07/21/2026, 20:10:44 UTC Added: 07/21/2026, 20:52:49 UTC |
