Apple did not merchandise further details connected however the bug is being exploited, oregon supply immoderate indicators of compromise (IoCs), which is modular signifier astatine Cupertino.

Such issues person plagued Apple of late, with the steadfast having patched multiple different vulnerabilities impacting instrumentality kernels so acold this year.

The different issues fixed successful Apple’s latest barebones information advisory are:

CVE-2022-42835 successful AppleMobileFileIntegrity;
CVE-2022-32940 successful AVEVideoEncoder;
