One of these virutal mappings can be freed along with the physical page, allowing for a read/write UAF via the second mapping\n\n\n\nThe second virtual mapping references a physical address that has been freed after the first virtual mapping has been freed. This allows the physical memory to be allocated (for example) by another process and read/written to.","published":"2026-07-10T21:16:54.000Z","lastModified":"2026-10-25T15:10:00.000Z","status":"Analyzed","sourceIdentifier":"367425dc-4d06-4041-9650-c2dc6aaa27ce","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-416"],"affected":["imaginationtech/ddk"],"epss":{"score":0.00167,"percentile":0.0592,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%).
