CVE-2019-2182

In the Android kernel in the kernel MMU code there is a possible execution path leaving some kernel text and rodata pages writable. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...

CVE-2018-12891

An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions...

CVE-2018-12891

CVE-2018-12891 affects the Xen hypervisor. A flaw in PV MMU preemption checks allows a malicious/badly-behaved PV guest to bypass preemption and potentially run an unbounded number of iterations, causing a Denial of Service that can freeze the host. Affected are Xen versions through 4.10.x (and o...
