DescriptionCVE.org

On arm64, a WASM br_table instruction with a lot of entries could lead to the label being too far from the instruction causing truncation and incorrect computation of the branch address. This vulnerability was fixed in Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13, and Thunderbird 140.1.

AnalysisAI

WebAssembly JIT compiler on ARM64 architectures incorrectly calculates branch addresses when processing WASM br_table instructions with numerous entries, enabling remote code execution in Firefox <141, Firefox ESR <115.26/128.13/140.1, and Thunderbird <141/128.13/140.1. The vulnerability requires no authentication or user interaction (CVSS AV:N/AC:L/PR:N/UI:N), allowing network-based attackers to potentially execute arbitrary code through malicious WASM content. Vendor-released patches are available across all affected product lines. No public exploit identified at time of analysis, though the CVSS 9.8 critical rating reflects the theoretical severity of unauthenticated remote code execution.
