A localattacker could use this to expose sensitive information (kernel memory).
25 device driver in the linux kernel didnot properly deallocate memory in some error conditions.
A local privilegedattacker could use this to cause a denial of service (kernel memoryexhaustion).

CVSS V3 rated as Medium - 5.5 severity.

CVSS V2 rated as Low - 1.9 severity.
