If the user later unmaps a dma mapping, locked_vm underflows\nto a large unsigned value, and a subsequent dma map request fails with\nENOMEM in __account_locked_vm.\n\nTo avoid underflow, grab and save the mm at the time a dma is mapped.\nUse that mm when adjusting locked_vm, rather than re-acquiring the saved\ntask's mm, which may have changed.  If the saved mm is dead, do nothing.\n\nlocked_vm is incremented for existing mappings in a subsequent patch."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.6","versionEndExcluding":"5.10.173","matchCriteriaId":"B3D65565-A7D5-494E-BE36-DE258E7C929A"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.99","matchCriteriaId":"5B8B2AC9-2F31-4A0F-96F5-7E26B50B27BB"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.16","matchCriteriaId":"0FD95FDA-6525-4B13-B3FB-49D9995FD8ED"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.2.3","matchCriteriaId":"88C67289-22AD-4CA9-B202-5F5A80E5BA4B"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/046eca5018f8a5dd1dc2cedf87fb5843b9ea3026","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/5a271242716846cc016736fb76be2b40ee49b0c3","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a6b2aabe664098d5cf877ae0fd96459464a30e17","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/b0790dff0760b7734cf0961f497ad64628ca550b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/eafb81c50da899dd80b340c841277acc4a1945b7","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
