CVE-2026-70632

FFmpeg versions from 4.4 up to, but not including, 9.0 contain an out-of-bounds heap write vulnerability in the native GoPro CineForm HD CFHD decoder that allows remote attackers to corrupt heap memory by supplying a crafted AVI file during stream probing. The cfhddecode function fails to enforce...

CVE-2026-70631

FFmpeg versions from 0.5 up to, but not including, 9.0 contain an uninitialized heap memory disclosure vulnerability in the native TIFF decoder in libavcodec/tiff.c. An attacker who can cause FFmpeg to decode a crafted TIFF file can supply a valid Deflate-compressed strip that terminates...

CVE-2026-70631

FFmpeg vulnerable before 9.0: uninitialized heap memory read in the TIFF decoder (libavcodec/tiff.c) when decoding a crafted TIFF with a Deflate strip; tiff_unpack_zlib() allocates a full declared strip buffer but copies bytes unconditionally, exposing stale heap data in output. No remediation de...

CVE-2026-5855 Contiki-NG LwM2M TLV Parser Out-of-Bounds Read via Unchecked Buffer Length in lwm2m_tlv_read

Contiki-NG's LwM2M TLV parser lwm2mtlvread in os/services/lwm2m/lwm2m-tlv.c ignores its caller-supplied buffer length argument and reads up to six bytes from the input buffer with no bounds check. The caller in lwm2m-engine.c iterates while there is at least one byte remaining, so a crafted CoAP...

CVE-2026-43629 llama.cpp b4882–b9058 Buffer Overflow in KV Cache State Restore

llama.cpp builds b4882 through b9058 contain a heap buffer overflow vulnerability in the KV cache state restore path where the statereaddata function computes write size without overflow checking, allowing attackers with write access to the slotsavepath directory to corrupt heap memory. Attackers...

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...

AZL-94496 CVE-2026-19027 affecting package hdf5 1.14.6-4

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 prior to 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap...
