Given the CVE-2025-31200 identifier, the flaw was discovered by Apple and the Google Threat analysis group. This would lead to the execution of the code when processing an audio flow in a maliciously manufactured multimedia file. Apple has solved the problem of corruption of memory with an improved limits verification.
The second defect was discovered in a safety characteristic itself; RPAC framework (Audio control remotely for participants). Although it allows communication between audio flows, the vulnerability caused an attacker with a capacity for reading and arbitrary writing to bypass the authentication of the pointer. The vulnerability was discovered by Apple, given the CVE-2025-31201 identifier, and has been corrected by deleting the vulnerable code.
Although security defects have been rectified, society claims that it is aware that the two problems may have been exploited in an extremely sophisticated attack against specific targeted individuals on iOS.
In addition to the security fixes, the Changelog indicates that the update also deals with a bug which “prevents carplay wireless connection in certain vehicles”.
