the first clears the slot, and the second\ndereferences a NULL pointer.\n\nCheck and update the slot under config_lock in both paths."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/amd/pds_core/auxbus.c"], "versions": [{"version": "0861fccd43b8bafb533d97308862d20b7db3a2ad", "lessThan": "646b58b543f3bb1641e9123b75ff7799fe7b42f1", "status": "affected", "versionType": "git"}, {"version": "f41e27b746241e57d968d1d61c008322338ca258", "lessThan": "ef194751fed50cf3452017b63f00142a0ab40c70", "status": "affected", "versionType": "git"}, {"version": "b699bdc720c0255d1bb76cecba7382c1f2107af5", "lessThan": "cf0ed2ba202f5c3b300ec1bf7ff0b5d555f7d518", "status": "affected", "versionType": "git"}, {"version": "b699bdc720c0255d1bb76cecba7382c1f2107af5", "lessThan": "bdeab32a7a91acd295d52a2d4ab1cc3f2da5e454", "status": "affected", "versionType": "git"}, {"version": "b699bdc720c0255d1bb76cecba7382c1f2107af5", "lessThan": "bfa33cd513c7ceb93c5a4c30e5662acd73c0a916", "status": "affected", "versionType": "git"}, {"version": "fec5f7af1d5f64a38f9224cd27b274d1af55a7ed", "status": "affected", "versionType": "git"}, {"version": "6.6.90", "lessThan": "6.6.148", "status": "affected", "versionType": "semver"}, {"version": "6.12.28", "lessThan": "6.12.101", "status": "affected", "versionType": "semver"}, {"version": "6.14.6", "lessThan": "6.15", "status": "affected", "versionType": "semver"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/amd/pds_core/auxbus.c"], "versions": [{"version": "6.15", "status": "affected"}, {"version": "0", "lessThan": "6.15", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.148", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.101", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.42", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.6", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc5", "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": "6.6.90", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.12.28", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "7.2-rc5"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.14.6"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/646b58b543f3bb1641e9123b75ff7799fe7b42f1"}, {"url": "https://git.kernel.org/stable/c/ef194751fed50cf3452017b63f00142a0ab40c70"}, {"url": "https://git.kernel.org/stable/c/cf0ed2ba202f5c3b300ec1bf7ff0b5d555f7d518"}, {"url": "https://git.kernel.org/stable/c/bdeab32a7a91acd295d52a2d4ab1cc3f2da5e454"}, {"url": "https://git.kernel.org/stable/c/bfa33cd513c7ceb93c5a4c30e5662acd73c0a916"}], "title": "pds_core: fix auxiliary device add/del races", "x_generator": {"engine": "bippy-1.2.0"}}}}
