Denial of service in Apple iOS, macOS, and related operating systems due to a use-after-free flaw could allow a malicious app to crash the device. Apple's advisory only confirms unexpected system termination, but an independent CVSS score of 9.8 suggests potential for full system compromise; however, the CVSS vector appears inconsistent with the vendor description. The vulnerability is patched in versions 26.6 for all affected OSes, and no active exploitation or public exploit code is known.

Attack Technique
Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.
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 attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
