CVE-2017-15951

High 7.8

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.

Affected products and versions

linux linux_kernel · 4.10 → 4.13.10
linux linux_kernel · 4.4 → 4.4.95
linux linux_kernel · 4.5 → 4.9.59
