CVE-2022-45409
The garbage collector could have been aborted in several states and zones and <code>GCRuntime::finishCollection</code> may not have been called, leading to a use-after-free and potentially exploitable crash.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
