This sequence is guaranteed by driver file\noperations. Therefore, there is no need to destroy an already empty\nfile_ida when the WQ cdev is removed.\n\nWorse, ida_free() in cdev release may happen after destruction of\nfile_ida per WQ cdev. This can lead to accessing an id in file_ida\nafter it has been destroyed, resulting in a kernel panic.\n\nRemove ida_destroy(&file_ida) to address these issues."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/dma/idxd/cdev.c"],"versions":[{"version":"e6fd6d7e5f0fe4a17a08e892afb5db800e7794ec","lessThan":"9eb15f24a0b9b017b39cde8b8c07243676b63687","status":"affected","versionType":"git"},{"version":"e6fd6d7e5f0fe4a17a08e892afb5db800e7794ec","lessThan":"15edb906211bf53e7b5574f7326ab734d6bff4f9","status":"affected","versionType":"git"},{"version":"e6fd6d7e5f0fe4a17a08e892afb5db800e7794ec","lessThan":"76e43fa6a456787bad31b8d0daeabda27351a480","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/dma/idxd/cdev.c"],"versions":[{"version":"6.4","status":"affected"},{"version":"0","lessThan":"6.4","status":"unaffected","versionType":"semver"},{"version":"6.6.33","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.4","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":"6.6.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.9.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9eb15f24a0b9b017b39cde8b8c07243676b63687"},{"url":"https://git.kernel.org/stable/c/15edb906211bf53e7b5574f7326ab734d6bff4f9"},{"url":"https://git.kernel.org/stable/c/76e43fa6a456787bad31b8d0daeabda27351a480"}],"title":"dmaengine: idxd: Avoid unnecessary destruction of file_ida","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-06-21T13:46:11.658594Z","id":"CVE-2024-38629","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-21T13:46:25.705Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T04:12:25.953Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/9eb15f24a0b9b017b39cde8b8c07243676b63687","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/15edb906211bf53e7b5574f7326ab734d6bff4f9","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/76e43fa6a456787bad31b8d0daeabda27351a480","tags":["x_transferred"]}]}]}}
