It responds to all\noutstanding iopf's with an IOMMU_PAGE_RESP_INVALID code and detaches the\ndevice from the queue.\n\nHowever, it fails to release the group structure that represents a group\nof iopf's awaiting for a response after responding to the hardware. This\ncan cause a memory leak if iopf_queue_remove_device() is called with\npending iopf's.\n\nFix it by calling iopf_free_group() after the iopf group is responded."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/iommu/io-pgfault.c"],"versions":[{"version":"19911232713573a2ebea84a25bd4d71d024ed86b","lessThan":"db60d2d896a17decd58d143eef92cf22eb0a0176","status":"affected","versionType":"git"},{"version":"19911232713573a2ebea84a25bd4d71d024ed86b","lessThan":"90d5429cd2921ca2714684ed525898d431bb9283","status":"affected","versionType":"git"},{"version":"19911232713573a2ebea84a25bd4d71d024ed86b","lessThan":"9759ae2cee7cd42b95f1c48aa3749bd02b5ddb08","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/iommu/io-pgfault.c"],"versions":[{"version":"6.9","status":"affected"},{"version":"0","lessThan":"6.9","status":"unaffected","versionType":"semver"},{"version":"6.12.16","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13.4","lessThanOrEqual":"6.13.*","status":"unaffected","versionType":"semver"},{"version":"6.14","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":"6.9","versionEndExcluding":"6.12.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9","versionEndExcluding":"6.13.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9","versionEndExcluding":"6.14"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/db60d2d896a17decd58d143eef92cf22eb0a0176"},{"url":"https://git.kernel.org/stable/c/90d5429cd2921ca2714684ed525898d431bb9283"},{"url":"https://git.kernel.org/stable/c/9759ae2cee7cd42b95f1c48aa3749bd02b5ddb08"}],"title":"iommu: Fix potential memory leak in iopf_queue_remove_device()","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.5,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"id":"CVE-2025-21770","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2025-10-01T19:30:41.180209Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-401","description":"CWE-401 Missing Release of Memory after Effective Lifetime"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-10-01T19:36:40.725Z"}}]}}
