Type Values Removed Values Added
Description In the Linux kernel, the following vulnerability has been resolved: x86/sev: Do not touch VMSA pages during SNP guest memory kdump When kdump is running makedumpfile to generate vmcore and dump SNP guest memory it touches the VMSA page of the vCPU executing kdump. It then results in unrecoverable #NPF/RMP faults as the VMSA page is marked busy/in-use when the vCPU is running and subsequently a causes guest softlockup/hang. Additionally, other APs may be halted in guest mode and their VMSA pages are marked busy and touching these VMSA pages during guest memory dump will also cause #NPF. Issue AP_DESTROY GHCB calls on other APs to ensure they are kicked out of guest mode and then clear the VMSA bit on their VMSA pages. If the vCPU running kdump is an AP, mark it's VMSA page as offline to ensure that makedumpfile excludes that page while dumping guest memory. This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
