However, the early failure path after the first acquire_bus()\ncall uses a bare 'return ret;', which leaks dma_buffer whenever the bus\nacquire fails.\n\nReplace the early return with goto fail so the existing cleanup path\nruns.\n\nFound via a custom Coccinelle semantic patch hunting for kmalloc'd\nlocals leaked on early-return error paths in driver firmware-download\ncode."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/wireless/microchip/wilc1000/wlan.c"], "versions": [{"version": "1241c5650ff7a0236cebb89acca8aade48839fd6", "lessThan": "95c82d498d74c4e587db30021ca1aec90e29b5a5", "status": "affected", "versionType": "git"}, {"version": "1241c5650ff7a0236cebb89acca8aade48839fd6", "lessThan": "32d7584441b9ecb279a03653b432612546e5efbe", "status": "affected", "versionType": "git"}, {"version": "1241c5650ff7a0236cebb89acca8aade48839fd6", "lessThan": "dd7b6a8671939708cc4b7a46786d8c11297e8f69", "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/net/wireless/microchip/wilc1000/wlan.c"], "versions": [{"version": "6.13", "status": "affected"}, {"version": "0", "lessThan": "6.13", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.34", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.11", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "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": "6.13", "versionEndExcluding": "6.18.34"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.0.11"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/95c82d498d74c4e587db30021ca1aec90e29b5a5"}, {"url": "https://git.kernel.org/stable/c/32d7584441b9ecb279a03653b432612546e5efbe"}, {"url": "https://git.kernel.org/stable/c/dd7b6a8671939708cc4b7a46786d8c11297e8f69"}], "title": "wifi: wilc1000: fix dma_buffer leak on bus acquire failure", "x_generator": {"engine": "bippy-1.2.0"}}}}
