The commit in\n\"Fixes\" introduces some clean-up codes in case of allocation failure,\nwhich free memory in reverse order with 'i' decreasing to 0. However,\nthere are some problems:\n  - The case i=0 is left out. Thus memory is leaked.\n  - In case memory allocation fails right from the start, the memory\n    freeing loops will start with i=-1 and invalid memory locations will\n    be accessed.\n\nOne of these loops has been fixed in commit c8ff91535880 (\"staging:\nvt6655: fix potential memory leak\"). Fix the remaining erroneous loops."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/staging/vt6655/device_main.c"],"versions":[{"version":"5341ee0adb17d12a96dc5344e0d267cd12b52135","lessThan":"637672a71f5016a40b0a6c0f3c8ad25eacedc8c3","status":"affected","versionType":"git"},{"version":"5341ee0adb17d12a96dc5344e0d267cd12b52135","lessThan":"88b9cc60f26e8a05d1ddbddf91b09ca2915f20e0","status":"affected","versionType":"git"},{"version":"5341ee0adb17d12a96dc5344e0d267cd12b52135","lessThan":"95ac62e8545be2b0a8cae0beef7c682e2e470e48","status":"affected","versionType":"git"},{"version":"5341ee0adb17d12a96dc5344e0d267cd12b52135","lessThan":"f19e5b7df54590c831f350381963f25585c8f7d5","status":"affected","versionType":"git"},{"version":"5341ee0adb17d12a96dc5344e0d267cd12b52135","lessThan":"a9e9806d1c315bc50dce05479a079b9a104474b8","status":"affected","versionType":"git"},{"version":"5341ee0adb17d12a96dc5344e0d267cd12b52135","lessThan":"ed11b73c963292e7b49c0f37025c58ed3b7921d6","status":"affected","versionType":"git"},{"version":"5341ee0adb17d12a96dc5344e0d267cd12b52135","lessThan":"2a2db520e3ca5aafba7c211abfd397666c9b5f9d","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/staging/vt6655/device_main.c"],"versions":[{"version":"4.18","status":"affected"},{"version":"0","lessThan":"4.18","status":"unaffected","versionType":"semver"},{"version":"4.19.262","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.220","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.150","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.75","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.19.17","lessThanOrEqual":"5.19.*","status":"unaffected","versionType":"semver"},{"version":"6.0.3","lessThanOrEqual":"6.0.*","status":"unaffected","versionType":"semver"},{"version":"6.1","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":"4.18","versionEndExcluding":"4.19.262"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.18","versionEndExcluding":"5.4.220"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.18","versionEndExcluding":"5.10.150"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.18","versionEndExcluding":"5.15.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.18","versionEndExcluding":"5.19.17"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.18","versionEndExcluding":"6.0.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.18","versionEndExcluding":"6.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/637672a71f5016a40b0a6c0f3c8ad25eacedc8c3"},{"url":"https://git.kernel.org/stable/c/88b9cc60f26e8a05d1ddbddf91b09ca2915f20e0"},{"url":"https://git.kernel.org/stable/c/95ac62e8545be2b0a8cae0beef7c682e2e470e48"},{"url":"https://git.kernel.org/stable/c/f19e5b7df54590c831f350381963f25585c8f7d5"},{"url":"https://git.kernel.org/stable/c/a9e9806d1c315bc50dce05479a079b9a104474b8"},{"url":"https://git.kernel.org/stable/c/ed11b73c963292e7b49c0f37025c58ed3b7921d6"},{"url":"https://git.kernel.org/stable/c/2a2db520e3ca5aafba7c211abfd397666c9b5f9d"}],"title":"staging: vt6655: fix some erroneous memory clean-up loops","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-2022-50355","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-01-14T18:31:51.758929Z"}}}],"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":"2026-01-14T18:33:00.943Z"}}]}}
