CVE-2026-32882
CVE-2026-32882 – libheif heap buffer OOB read : In libheif 1.21.2 and earlier, a flaw in HeifPixelImage::overlay() allows a heap buffer over-read during overlay compositing when the child image uses a different bit depth for alpha than color channels. Specifically, the code indexes the alpha plan...
CVE-2026-32882 libheif: Heap Buffer OOB Read in overlay compositing due to wrong alpha stride
libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and prior contain a heap buffer over-read in HeifPixelImage::overlay in libheif/pixelimage.cc. When compositing an overlay image iovl whose child image has a different bit depth for the alpha channel than for the color...

CVE-2026-32741
CVE-2026-32741 affects libheif 1.21.2 and earlier. The heap buffer overflow occurs in MaskImageCodec::decode_mask_image() when decoding a HEIF file containing a mask image; the function copies data.size() bytes into a pixel buffer sized by image dimensions using a single memcpy without an upper-b...

CVE-2026-32814 libheif: Uninitialized Heap Memory Information Leak via Failed Grid Tiles
libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, when decoding a HEIF grid image with strictdecoding=false the default, a corrupted tile silently fails to decode and the library returns heiferrorOk with no indication of failure, leading to an uninitialized...

CVE-2026-32814
CVE-2026-32814 concerns the libheif HEIF/AVIF decoder. In versions up to 1.21.2, decoding a grid image with default strict_decoding=false could silently fail to decode a tile, returning heif_error_Ok while leaking uninitialized heap memory as pixel data (Y, Cb, Cr planes). The canvas is allocated...
