For example, if no\nprocess has the fbdev chardev opened by the time the driver is removed.\n\nIf that's the case, fb_info will be freed when unregister_framebuffer() is\ncalled, making the fb_info pointer accessed in vesafb_remove() after that\nto no longer be valid.\n\nTo prevent that, move the expression containing the info->par to happen\nbefore the unregister_framebuffer() function call."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/video/fbdev/vesafb.c"],"versions":[{"version":"f94aa46efaa087ec075c83e4508f943fb5e43977","lessThan":"0fac5f8fb1bc2fc4f8714bf5e743c9cc3f547c63","status":"affected","versionType":"git"},{"version":"a1aac13288de2935dc1a9330a93b1ac92f1e2b72","lessThan":"f605f5558ecc175ec70016a3c15f007cb6386531","status":"affected","versionType":"git"},{"version":"b3c9a924aab61adbc29df110006aa03afe1a78ba","lessThan":"d260cad015945d1f4bb9b028a096f648506106a2","status":"affected","versionType":"git"},{"version":"b3c9a924aab61adbc29df110006aa03afe1a78ba","lessThan":"acde4003efc16480375543638484d8f13f2e99a3","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/video/fbdev/vesafb.c"],"versions":[{"version":"5.18","status":"affected"},{"version":"0","lessThan":"5.18","status":"unaffected","versionType":"semver"},{"version":"5.15.46","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.17.14","lessThanOrEqual":"5.17.*","status":"unaffected","versionType":"semver"},{"version":"5.18.3","lessThanOrEqual":"5.18.*","status":"unaffected","versionType":"semver"},{"version":"5.19","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15.41","versionEndExcluding":"5.15.46"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17.9","versionEndExcluding":"5.17.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"5.18.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"5.19"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0fac5f8fb1bc2fc4f8714bf5e743c9cc3f547c63"},{"url":"https://git.kernel.org/stable/c/f605f5558ecc175ec70016a3c15f007cb6386531"},{"url":"https://git.kernel.org/stable/c/d260cad015945d1f4bb9b028a096f648506106a2"},{"url":"https://git.kernel.org/stable/c/acde4003efc16480375543638484d8f13f2e99a3"}],"title":"video: fbdev: vesafb: Fix a use-after-free due early fb_info cleanup","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.8,"attackVector":"LOCAL","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"id":"CVE-2022-49419","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2025-02-27T18:16:14.940889Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-416","description":"CWE-416 Use After Free"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-02-27T18:22:33.091Z"}}]}}
