Go to dashboardA malicious mmproj file passed to the Pocket-TTS state-slot code in llama.cpp writes past the end of a heap buffer. Per the sources, a local attacker can use this to corrupt memory, and public exploit code exists, though current master and the latest release now abort on such files instead of silently writing.
Summary written from the sources below. Check the originals before acting.

Systems that run llama.cpp's Pocket-TTS or gen-audio code and load mmproj files, especially where other local users can supply those files. Hosts that do not use this path or only load trusted mmproj files can skip urgent action, though the upgrade still applies.

b11796, which the advisory names as fixed.b11796 or later, as the advisory recommends.b11871, which aborts on a malformed mmproj instead of writing out of bounds.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
A weakness has been identified in ggml-org llama.cpp. Affected by this issue is the function list_pockettts_state_slots of the file tools/mtmd/models/pockettts-gen.cpp of the component Pocket-TTS. This manipulation of the argument mmproj causes out-of-bounds write. The attack requires local access. The exploit has been made available to the public and could be used for attacks. Upgrading to version b11796 can resolve this issue. Patch name: 0a1ef309cdbb9f2024f58a38fb4c42352c5db569. The affected component should be upgraded. The reported heap out‑of‑bounds write (gen‑audio / pocket‑tts state_out path) is no longer a silent exploitable heap write on current master and the latest release b11871 - a malicious mmproj that previously triggered it now trips a release‑active GGML_ASSERT and aborts. But the submitter's recommended by‑construction fix (PR #29360 "prevent OOB accesses from malformed mmproj files") is still open. So the root cause is detected‑and‑aborted, not prevented‑by‑design.
