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":"2026-08-19T15:17:09.81+00:00","modifiedAt":"2026-10-27T13:10:00.36+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:H","score":7.3,"severity":"HIGH"}],"references":["https://github.com/tirr-c/jxl-oxide/commit/3986dadd3926a95656a642e74a0702d52f5c92e2","https://github.com/tirr-c/jxl-oxide/releases/tag/0.12.6","https://github.com/tirr-c/jxl-oxide/security/advisories/GHSA-5pmv-rx8r-wmv5","https://rustsec.org/advisories/RUSTSEC-2026-0151.html"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-52834","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-122","CWE-131","CWE-190"],"productCriteria":[],"sourceDates":{"published":"2026-08-19T15:17:09.810","lastModified":"2026-10-27T13:10:00.360"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
