When not true it leads to a null pointer\ndereference looking up the region name.\n\nThis appears during testing of region lookup after a failure to\nassemble a BIOS defined region or if the lookup raced with the\nassembly of the BIOS defined region.\n\nFailure to clean up BIOS defined regions that fail assembly is an\nissue in itself and a fix to that problem will alleviate some of\nthe impact. It will not alleviate the race condition so let's harden\nthis path.\n\nThe behavior change is that the kernel oops due to a null pointer\ndereference is replaced with a dev_dbg() message noting that an\nendpoint was mapped.\n\nAdditional comments are added so that future users of this function\ncan more clearly understand what it provides."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/cxl/core/region.c"],"versions":[{"version":"0a105ab28a4de44eb738ce64e9ac74946aa5133b","lessThan":"a9e099e29e925f8b31cfe53e8a786b9796f8e453","status":"affected","versionType":"git"},{"version":"0a105ab28a4de44eb738ce64e9ac74946aa5133b","lessThan":"b8a40a6dbfb0150c1081384caa9bbe28ce5d5060","status":"affected","versionType":"git"},{"version":"0a105ab28a4de44eb738ce64e9ac74946aa5133b","lessThan":"285f2a08841432fc3e498b1cd00cce5216cdf189","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/cxl/core/region.c"],"versions":[{"version":"6.4","status":"affected"},{"version":"0","lessThan":"6.4","status":"unaffected","versionType":"semver"},{"version":"6.6.37","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.8","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","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":"6.4","versionEndExcluding":"6.6.37"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.9.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a9e099e29e925f8b31cfe53e8a786b9796f8e453"},{"url":"https://git.kernel.org/stable/c/b8a40a6dbfb0150c1081384caa9bbe28ce5d5060"},{"url":"https://git.kernel.org/stable/c/285f2a08841432fc3e498b1cd00cce5216cdf189"}],"title":"cxl/region: Avoid null pointer dereference in region lookup","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T04:46:51.020Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/a9e099e29e925f8b31cfe53e8a786b9796f8e453","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/b8a40a6dbfb0150c1081384caa9bbe28ce5d5060","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/285f2a08841432fc3e498b1cd00cce5216cdf189","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-41084","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T16:20:55.485513Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-11T17:33:59.089Z"}}]}}
