Doc Type: If docs needed, set a value
Doc Text:
A race has been observed on a PFN which falls into the device memory region with the system memory configuration where PFN's are such that [ZONE_NORMAL ZONE_DEVICE ZONE_NORMAL]. Since normal zone start and end pfn contains the device memory PFN's as well, the compaction triggered will try on the device memory PFN's too though they end up in NOP. This may lead to compromised Availability.

Comment 10 Alex 2024-06-09 15:28:57 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52489 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags READ LOCK DANGER NULLPTR RACE  ; these flags parsed automatically based on patche data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
