A module with a sufficiently large signature field causes a stack overflow, affecting secure kernel data pages. This can be leveraged to obtain arbitrary code execution in secure supervisor context by overwriting a SHA256 function pointer in the secure kernel data area when loading a forged, unsigned SK_LOAD module encrypted with the CEK (obtainable through CVE-2022-25332). This constitutes a full break of the TEE security architecture."}],"problemTypes":[{"descriptions":[{"lang":"en","cweId":"CWE-121","description":"Stack-based Buffer Overflow","type":"CWE"}]}],"providerMetadata":{"orgId":"cf4a7ff5-dd38-4ede-a530-ffaa7ea59c39","shortName":"NCSC-NL","dateUpdated":"2024-07-15T00:27:54.327Z"},"references":[{"name":"TETRA:BURST","tags":["related"],"url":"https://tetraburst.com/"}],"credits":[{"lang":"en","value":"Midnight Blue","type":"finder"}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"version":"3.1","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"HIGH","baseScore":8.2,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H/E:F/RL:U/RC:C/CR:H/IR:H/AR:H/MAV:L/MAC:L/MPR:H/MUI:N/MS:C/MC:H/MI:H/MA:H"}}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T04:36:06.873Z"},"title":"CVE Program Container","references":[{"name":"TETRA:BURST","tags":["related","x_transferred"],"url":"https://tetraburst.com/"}]}]}}
