CVE-2026-70638

CVE-2026-70638 affects the llama.cpp project, specifically the LLaMA-Android JNI wrapper. Versions b1886–b7445 are vulnerable due to an integer overflow in new_1batch(), which multiplies sizeof(llama_seq_id) by an attacker-controlled n_seq_max without overflow validation, causing the heap allocat...

EUVD-2026-53678

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 through 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...
