CVE-2026-116829 | BDVDB-2026-396449 Detail
ggml-orgllama.cpp
Description#
llama.cpp b10398 before b11301 contains an integer overflow vulnerability in gguf_init_from_reader that allows attackers to bypass tensor element-count validation by supplying shapes whose product wraps to zero. Attackers can craft GGUF files with enormous tensor extents that overflow ggml_nbytes() and strides, causing out-of-bounds memory access when buffers are sized from wrapped byte counts.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact high. Attack vector: local.
Weaknesses#
- CWE-190 Integer Overflow or Wraparound
