libheif: libheif is a HEIF and AVIF file format decoder and encoder
CVE-2026-49271 is fixed in 27 products on 1 platform, first by SUSE-SU-2026:22153-1, released June 17, 2026. It is not reported as exploited. Patch Radar priority: Routine.
libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offsets using unit_offset + unit_size. Because the addition can wrap, a crafted HEIF file can pass the range check and then construct a vector from iterators outside the compressed item buffer, producing an out-of-bounds heap read and crash. Version 1.22.1 patches the issue.
