CVE-2022-50875

CVE-2022-50875 — Linux kernel (overlay): The issue is a null pointer dereference in overlay code, specifically in find_dup_cset_node_entry() and find_dup_cset_prop(). If kmalloc() fails during kasprintf(), fn_1 or fn_2 may be NULL, and a subsequent strcmp() can dereference NULL. The vulnerability...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the HeifPixelImage::overlay function. An attacker can cause a crash by supplying a crafted HEIF file with a malicious iovl overlay box that triggers a negative row length calculation, leading to a large...

CVE-2025-68431

libheif is an HEIF and AVIF file format decoder and encoder. Prior to version 1.21.0, a crafted HEIF that exercises the overlay image item path triggers a heap buffer over-read in HeifPixelImage::overlay. The function computes a negative row length likely from an unclipped overlay rectangle or...
