Detailsinfo

A vulnerability, which was classified as problematic, has been found in Apple watchOS (Smartwatch Operating System) (version now known). Affected by this issue is some unknown processing of the component RSA PKCS Private Key Handler. The manipulation with an unknown input leads to a channel accessible vulnerability. Using CWE to declare the problem leads to CWE-300. The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint. Impacted is availability. CVE summarizes:

A timing side-channel issue was addressed with improvements to constant-time computation in cryptographic functions. This issue is fixed in iOS 16.7.6 and iPadOS 16.7.6, iOS 17.3 and iPadOS 17.3, macOS Monterey 12.7.4, macOS Sonoma 14.3, macOS Ventura 13.6.5, tvOS 17.3, watchOS 10.3. An attacker may be able to decrypt legacy RSA PKCS#1 v1.5 ciphertexts without having the private key.

The weakness was presented 01/23/2024. The advisory is shared for download at support.apple.com. This vulnerability is handled as CVE-2024-23218 since 01/12/2024. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1557.
