NVD Description

Note: Versions mentioned in the description apply only to the upstream llama.cpp package and not the llama.cpp package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

llama.cpp builds b4882 before b8487 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 an oversized seq_id value to trigger an out-of-bounds read that leaks heap data including pointer values into server logs, defeating ASLR protections and facilitating further exploitation.
