Memory corruption via oversized GLSL private allocation
Published Jul 9, 2024 · Updated Oct 30, 2025
Memory corruption in Mozilla Firefox before 128, Firefox ESR before 115.13, and Thunderbird before 128 allows remote attackers to corrupt memory. ANGLE's GLSL translator accepts private shader-memory allocations exceeding 8,192 integers, allowing an out-of-bounds access during allocation on macOS. Exploitation requires a macOS user to render attacker-controlled WebGL content; the published record reports memory corruption but not code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
