Certain types of allocations were missing annotations that, if the Garbage Collector was in a specific state, could have lead to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 106, Firefox ESR < 102.4, and Thunderbird < 102.4.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
