CVE-2026-84286

ExLlamaV3’s EXL3 loader uses an untrusted, model-supplied index to select a CUDA kernel without first verifying that the index is within bounds. A malicious model can force the code to read and invoke an out‑of‑range function pointer, resulting in a reproducible crash. Under specific conditions...

CVE-2026-84286 OOB Read/Write via Negative Array Index in exllamav3_ext Kernel Table

ExLlamaV3’s EXL3 loader uses an untrusted, model-supplied index to select a CUDA kernel without first verifying that the index is within bounds. A malicious model can force the code to read and invoke an out‑of‑range function pointer, resulting in a reproducible crash. Under specific conditions...

CVE-2026-84286

The exllamav3_ext CUDA extension contains an out-of-bounds (OOB) memory access vulnerability in its kernel-table dispatch process. The root cause is a lack of bounds checking where the checkpoint-derived block index (cbi ) is used to access a fixed 24-entry array. If a crafted input sets the kern...

CVE-2026-84286: Improper Input Validation

ExLlamaV3’s EXL3 loader uses an untrusted, model-supplied index to select a CUDA kernel without first verifying that the index is within bounds. A malicious model can force the code to read and invoke an out‑of‑range function pointer, resulting in a reproducible crash. Under specific conditions...

CVE-2026-102710

Attacker model / Preconditions: a loaded TXMMODULEUSERMODE | TXMMODULEMEMORYPROTECTION module issuing kernel dispatch calls, on a build with TXENABLEEVENTTRACE. A user-mode, memory-protected module can register an arbitrary function pointer as the global trace-full callback. The kernel calls it...
