OracleVM 3.4 : xen (OVMSA-2022-0029)

medium Nessus Plugin ID 168501

Language:

Synopsis

The remote OracleVM host is missing one or more security updates.

Description

The remote OracleVM system is missing necessary patches to address security updates:

 - P2M pool freeing may take excessively long The P2M pool backing second level address translation for guests may be of significant size. Therefore its freeing may take more time than is reasonable without intermediate preemption checks. Such checking for the need to preempt was so far missing. (CVE-2022-33746)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected xen / xen-tools packages.
