Update the logic to\ncalculate the final D value based on the range.","modified":"2026-03-20T12:22:15.009791Z","published":"2025-02-26T01:55:37.095Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49189.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/334720f418f57b1d969dad2117b21f9388cb9395"},{"type":"WEB","url":"https://git.kernel.org/stable/c/34dca60982e93e69ae442aa2d36ce61c9a3bb563"},{"type":"WEB","url":"https://git.kernel.org/stable/c/52592f9afbfe01bce8f8953e4f19cbe3bcbdbd3a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/58922910add18583d5273c2edcdb9fd7bf4eca02"},{"type":"WEB","url":"https://git.kernel.org/stable/c/96888f0dcf351e758b9df57e015a48427ca709c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a4e2e31971354790b0d1fa3e783452a9d135fcff"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49189.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49189"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"99cbd064b059f222c8839ba433a68b2d6ee33066"},{"fixed":"52592f9afbfe01bce8f8953e4f19cbe3bcbdbd3a"},{"fixed":"334720f418f57b1d969dad2117b21f9388cb9395"},{"fixed":"34dca60982e93e69ae442aa2d36ce61c9a3bb563"},{"fixed":"96888f0dcf351e758b9df57e015a48427ca709c1"},{"fixed":"a4e2e31971354790b0d1fa3e783452a9d135fcff"},{"fixed":"58922910add18583d5273c2edcdb9fd7bf4eca02"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-49189.json"}}],"schema_version":"1.7.5"}
