Prior to jxl-grid 0.6.2, decoding a crafted JPEG XL image on a 32-bit platform can overflow length calculations in AlignedGrid::with_alloc_tracker and related grid and subgrid arithmetic. A 65536 x 65536 frame can pass the frame-area limit while overflowing the usize element count, causing modular, VarDCT, or filter rendering paths to allocate a backing buffer smaller than the logical grid. A tiny bitstream-controlled cropped frame combined with a huge canvas or requested region can also reach the vulnerable composition path in crates/jxl-render/src/blend.rs through ordinary render_frame(). Later mutable subgrid and raw-pointer operations can then perform attacker-controlled out-of-bounds writes, causing memory corruption, denial of service, or arbitrary code execution. This issue is fixed in jxl-grid version 0.6.2.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:H","score":7.3,"severity":null}],"references":["https://github.com/tirr-c/jxl-oxide/security/advisories/GHSA-5pmv-rx8r-wmv5","https://github.com/tirr-c/jxl-oxide/commit/3986dadd3926a95656a642e74a0702d52f5c92e2","https://github.com/tirr-c/jxl-oxide/releases/tag/0.12.6","https://rustsec.org/advisories/RUSTSEC-2026-0151.html"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-62513","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 19, 2026, 2:55:32 PM","dateUpdated":"Aug 19, 2026, 6:19:05 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
