Impact

Memory corruption that can be exploited for arbitrary code execution, information disclosure, or denial of service. With a CVSS score of 8.8 (HIGH), this represents a significant risk.
Exploit ScenarioDerived

An attacker triggers a specific sequence of operations that causes the application to free a memory block and then reference it again, potentially executing attacker-controlled data.

Attack Technique

Use After Free HIGH

Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.

Memory Corruption HIGH

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Denial of Service MEDIUM

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
