Design/Logic Flaw

Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt in an unprivileged guest. The closing of an event channel is e.g. triggered by remova...

CVE-2023-46837

CVE-2023-46837 affects Xen on Arm. The vulnerability stems from overflow in cache-clean/invalidation helpers used during memory scrubbing, which can lead to undefined behavior and potential premature cache-write reordering, with no guarantee that writes reach memory before handing pages to guests...

CVE-2023-34324 Possible deadlock in Linux kernel event handling

Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt in an unprivileged guest. The closing of an event channel is e.g. triggered by remova...

CVE-2023-34321

CVE-2023-34321 concerns Arm’s cache-clean/invalidate helpers used during guest memory allocation. The arithmetic in these helpers can overflow, causing the cache cleaning/invalidation to be skipped and delaying guarantees that writes (e.g., during scrubbing) reach memory before handing pages to g...
