CVE-2026-84383
libheif is a HEIF and AVIF file format decoder and encoder. From 1.22.0 until 1.23.2, a crafted HEIF, HEIC, or AVIF item graph using nested iden and auxl references can make HeifPixelImage::transferchannelfromimageas append duplicate Alpha planes with different bit depths to mstorage...

CVE-2026-84383
libheif, a HEIF and AVIF decoder/encoder, is affected by a heap out-of-bounds write (CVSS 9.8 Critical) in versions 1.22.0 through 1.23.2. A crafted item graph using nested iden and auxl references causes scale_nearest_neighbor() to write 16-bit samples into an 8-bit Alpha plane allocation, with ...
