Description A race condition exists in the scan get next rmap item function in mm/ksm.c when Kernel SamePage Merging (KSM) is enabled. This issue allows local users to cause a denial of service, potentially resulting in a NULL pointer dereference, or possibly have other unspecified impacts via a crafted application.
