Detailsinfo

A vulnerability was found in ggml-org llama.cpp up to 0.17.1/b7445. It has been rated as critical. This issue affects the function new_1batch/free_1batch of the component LLaMA-Android JNI Wrapper. The manipulation with an unknown input leads to a double free vulnerability. Using CWE to declare the problem leads to CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

llama.cpp builds b1886 through b7445 contain a double free vulnerability in the LLaMA-Android JNI wrapper where new_1batch() allocates memory using malloc() while free_1batch() deallocates it using the C++ delete operator, causing heap metadata corruption. Attackers can trigger this memory management mismatch to cause denial of service through process crashes or potentially achieve arbitrary code execution depending on allocator state.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-43622 since 05/01/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details of the vulnerability are known, but there is no available exploit.
