Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 125
Description
The issue is related to the MarkStack assignment operator, part of the JavaScript engine, which could access uninitialized memory if used in a self-assignment. This could allow a remote attacker to cause a denial of service.
Recommendations
For versions prior to 125, update to a version that contains a fix for this issue to prevent potential exploitation. As a temporary workaround, consider restricting the use of the MarkStack assignment operator in self-assignments until a patch is available.
