**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability in the Linux kernel has been resolved, related to a soft lockup during memory acceptance. The issue occurs when the memory of the TD guest is large and the timeout of softlockup is set to 1 second. The softlockup detects that the watchdog on a single CPU has not been fed for a while, which can hurt not only the nmi watchdog but also the softlockup. The `accept memory` function is involved, and the `touch softlockup watchdog` function is used to skip the timeout check. The `try to accept memory`, `do huge pmd anonymous page`, `get page from freelist`, ` handle mm fault`, ` alloc pages`, and ` folio alloc` functions are also mentioned in the call trace. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
