There is at least one JS change in this cycle:

​https://hg.mozilla.org/releases/mozilla-esr115/rev/05ab058811bf716fb0552469fb806b1206a22542

and the associated bugzilla ticket is still not public. So it might be a security fix or not...

There are three vulnerabilities in Firefox that have to do with the JIT code which would likely mean that this is the impacted component

CVE-2024-3852: GetBoundName in the JIT returned the wrong object (High)

CVE-2024-3854: Out-of-bounds-read after mis-optimized switch statement (High)

CVE-2024-3857: Incorrect JITting of arguments led to use-after-free during garbage collection (High)

I'm thinking these three vulnerabilities are the ones since they are in the JIT component that mozjs provides.
