CVE-2026-52834

jxl-oxide is a pure Rust implementation of a JPEG XL decoder. Prior to jxl-grid 0.6.2, decoding a crafted JPEG XL image on a 32-bit platform can overflow length calculations in AlignedGrid::withalloctracker and related grid and subgrid arithmetic. A 65536 x 65536 frame can pass the frame-area lim...

CVE-2026-52834

The Rust crate jxl-grid (versions 0.1.1–0.5.3) computes width * height unchecked in AlignedGrid::with_alloc_tracker, which overflows usize on 32-bit targets, allocating undersized backing buffers. A crafted JPEG XL image decoded via render_frame() triggers out-of-bounds writes through mutable sub...

GHSA-66M8-C62J-H6V5 jxl-oxide: `FrameBuffer::new` creates out-of-bounds slices on overflow

Summary jxl-oxide exposes a public safe API that can construct an undersized FrameBuffer due to unchecked usize multiplication, which immediately trigger panic while initializing the buffer in normal decoding path. Additionally, calling the safe grouped buffer accessors afterward can create inval...
