    CVE-2017-15951

    Published: 28 Oct 2017Last Modified: 14 Mar 2026

    Summary:

    Details: The KEYS subsystem in the Linux kernel before 4.13.10 does not correctly synchronize the actions of updating versus finding a key in the "negative" state to avoid a race condition, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls.
