CVE-2026-43631

llama.cpp builds b7492 through the latest b9060 contains a use-after-free vulnerability in the vocab pointer of llama-server when the --sleep-idle-seconds feature is enabled, allowing unauthenticated remote attackers to execute arbitrary code. Attackers can trigger the vulnerability by sending...

CVE-2026-43630

llama.cpp builds b5702 through b7653 contain an out-of-bounds read vulnerability in the recurrent memory state restore path that allows attackers with write access to the slot save directory to read memory past the end of the allocated cells array. Attackers can craft a malicious slot file with a...

CVE-2026-43627

llama.cpp builds b1283 through b9058 contain an integer overflow vulnerability in the llamabatchinit function where unchecked multiplications in malloc calls can wrap past INT32MAX when computing allocation sizes. Attackers can pass specially crafted parameters to trigger integer overflow, causin...

CVE-2026-43622

llama.cpp builds b1886 through b7445 contain a double free vulnerability in the LLaMA-Android JNI wrapper where new1batch allocates memory using malloc while free1batch deallocates it using the C++ delete operator, causing heap metadata corruption. Attackers can trigger this memory management...

CVE-2026-43632

Concrete details found: In llama.cpp builds b7492–b9060, a use-after-free in llama-server affects six tokenization endpoints (/tokenize, /detokenize, /infill, /apply-template, /rerank, /anthropic/count_tokens). The vulnerability arises from a time-of-check-time-of-use race that allows bypassing t...

CVE-2026-43631

The CVE affects llama.cpp builds from b7492 to b9060, where a use-after-free in the vocab pointer of llama-server occurs when --sleep-idle-seconds is enabled. Unauthenticated remote attackers can trigger this by sending requests to affected endpoints as the server transitions to sleep mode, causi...

CVE-2026-43631 llama.cpp b7492–b9060 Use-After-Free RCE via llama-server

llama.cpp builds b7492 through the latest b9060 contains a use-after-free vulnerability in the vocab pointer of llama-server when the --sleep-idle-seconds feature is enabled, allowing unauthenticated remote attackers to execute arbitrary code. Attackers can trigger the vulnerability by sending...

CVE-2026-43629

The CVE-2026-43629 entry concerns llama.cpp builds b4882–b9058 with a heap buffer overflow in the KV cache state restore path. The root cause is state_read_data() computing the write size without overflow checks, enabling an attacker with write access to the slot_save_path directory to craft mali...

CVE-2026-43628

llama.cpp builds b3978–b9058 are affected by an integer underflow and out-of-bounds read in the DRY sampler. A crafted HTTP request with dry_allowed_length = INT32_MIN to /v1/completions or /v1/chat/completions can trigger a heap buffer underflow, enabling unauthenticated attackers to crash the s...
