CVE-2022-36123

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.18.13

Description The issue is related to the clear bss function in the Linux kernel, which is associated with errors in clearing the initial symbol of the block (.bss). This can allow an attacker to cause a denial of service or gain privileges, specifically affecting Xen PV guest OS users.

Recommendations For Linux kernel versions prior to 5.18.13, update to version 5.18.13 or later to resolve the issue. As a temporary workaround, consider restricting access to Xen PV guest OS to minimize the risk of exploitation.
