An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker-controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash. This vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird < 102.10.
