SUSE CVE-2020-25598

An issue was discovered in Xen 4.14.x. There is a missing unlock in the XENMEMacquireresource error path. The RCU Read, Copy, Update mechanism is a synchronisation primitive. A buggy error path in the XENMEMacquireresource exits without releasing an RCU reference, which is conceptually similar to...
