|---|---|---|---|---|---|---|---|
| CVE-2026-23555 | Hig | 7.1 | < 4.20.2_08-150700.3.28.1 | 4.20.2_08-150700.3.28.1 | Mar 23, 2026 | Any guest issuing a Xenstore command accessing a node using the (illegal) node path "/local/domain/", will crash xenstored due to a clobbered error indicator in xenstored when verifying the node path. Note that the crash is forced via a failing assert() statement in xenstored. I | |
| CVE-2026-23554 | Hig | 7.8 | < 4.20.2_08-150700.3.28.1 | 4.20.2_08-150700.3.28.1 | Mar 23, 2026 | The Intel EPT paging code uses an optimization to defer flushing of any cached EPT state until the p2m lock is dropped, so that multiple modifications done under the same locked region only issue a single flush. Freeing of paging structures however is not deferred until the flus | |
| CVE-2026-23553 | — | < 4.20.2_04-150700.3.22.1 | 4.20.2_04-150700.3.22.1 | Jan 28, 2026 | In the context switch logic Xen attempts to skip an IBPB in the case of a vCPU returning to a CPU on which it was the previous vCPU to run. While safe for Xen's isolation between vCPUs, this prevents the guest kernel correctly isolating between tasks. Consider: 1) vCPU runs on | ||

Some of these variables are written to with guest controlled data, of guest controllable size. That size can be larger than the variable, and bounding of the writes was missing. | ||

As a result a domain can still have access any 64bit memory BAR when such device is no longer assigned to the domain. For PV domains the p | ||
