A vulnerability, which was classified as problematic, was found in Linux Kernel (Operating System) (the affected version is unknown). This affects the function einj_error_inject
of the file drivers/acpi/apei/einj.c of the component EINJ. The manipulation with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on availability. The summary by CVE is:
The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set.
