The vulnerability affects the implementation of WASM technology in browsers like Firefox, Firefox ESR, and the email client Thunderbird. This allows attackers to trigger a service failure.

The vulnerability of the WASM technology implementation in Firefox browsers, Firefox ESR, and the Thunderbird email client is related to unlimited resource allocation. Exploiting this vulnerability can allow a malicious actor to cause service failures remotely...

CVE-2022-31146

CVE-2022-31146 affects Wasmtime (Cranelift) in the migration to the regalloc2 allocator (Wasmtime 0.37.0). The bug may cause metadata for reference-typed functions to be missing during GC, making the GC pass think there are no live references, leading to use-after-free when values are later acces...
