CVE-2026-116829
Last modified
CVE-2026-116829 is a medium-severity vulnerability rated 6.6/10 on the CVSS scale. 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.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
