RUSTSEC-2021-0089 Optional `Deserialize` implementations lacking validation

When activating the non-default feature serialize, most structs implement serde::Deserialize without sufficient validation. This allows breaking invariants in safe code, leading to: Undefined behavior in asstring methods which use std::str::fromutf8unchecked internally. Panics due to failed...

Name of the Vulnerable Software and Affected Versions: raw-cpuid crate versions prior to 9.1.1 Description: The issue arises when the non-default serialize feature is activated, allowing most structs to implement serde::Deserialize without sufficient validation. This can lead to breaking invarian...

The vulnerability of the KVM GET_EMULATED_CPUID request in Linux kernel, related to the operation exceeding the data buffer’s permissible limits, allows an attacker to compromise data integrity and cause service failures. [source-iocs-preserved const=KVM_GET_EMULATED_CPUID]

The vulnerability of the KVM GETEMULATEDCPUID function in Linux operating systems is related to the operation exceeding the permissible data buffer limits. Exploiting this vulnerability can allow an attacker to compromise data integrity and cause service failures. source-iocs-preserved...
