No affected components available
native_cpuid::cpuid_count() exposes the unsafe __cpuid_count() intrinsic from core::arch::x86 or core::arch::x86_64 as a safe function, and uses it internally, without checking the safety requirement:
- The CPU the program is currently running on supports the function being called.
CPUID is available in most, but not all, x86/x86_64 environments. The crate compiles only on these architectures, so others are unaffected. This issue is mitigated by the fact that affected programs are expected to crash deterministically every time.
The flaw has been fixed in v9.0.0, by intentionally breaking compilation when targeting SGX or 32-bit x86 without SSE. This covers all affected CPUs.
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
Probability that this vulnerability will be exploited in the wild within the next 30 days.
