kernel: lacks a certain clear operation for the block starting symbol (.bss) cause a denial of service or gain privileges
The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges.
A memory access flaw was found in the Linux kernel’s XEN hypervisor for the virtual machine. This flaw allows a local user to crash the system or potentially escalate their privileges on the system.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect
