Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the Chunk process when handling files with a samplesperchunk value of zero. An attacker can cause a segmentation fault and denial of service by providing a specially crafted HEIF file that triggers an unsigned...

CVE-2026-32738 libheif has a Heap OOB Read/SEGV Crash via Zero samples_per_chunk

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 792-byte HEIF sequence file with samplesperchunk=0 in the stsc box causes an unsigned integer underflow in the Chunk constructor mlastsample = 0 + 0 - 1 = UINT32MAX, mapping all samples to an empty...

CVE-2026-31770

The CVE-2026-31770 issue affects the Linux kernel hwmon/occ path. In occ_show_power_1(), the accumulator could be divided by update_tag without checking for zero when no samples have been collected, leading to a division-by-zero crash. A fix reuses occ_get_powr_avg() (which handles the zero-sampl...
