If that happens\nfor a matching table entry, the resource lookup still returns success and\nthe following trylock dereferences a NULL mutex pointer while opening the\nresource.\n\nnfp_resource_acquire() already treats failure to allocate the table mutex\nas -ENOMEM. Do the same for the resource mutex and fail the lookup before\npublishing the rest of the resource handle.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/netronome/nfp/nfpcore/nfp_resource.c"], "versions": [{"version": "f01a2161577d31b14581e0db3bbbdfa963f145b6", "lessThan": "6dbd428119cb1fd1b73cf6968c711f4ea964dc8b", "status": "affected", "versionType": "git"}, {"version": "f01a2161577d31b14581e0db3bbbdfa963f145b6", "lessThan": "cfa119aa781c4044dab5b4c1e5864600f53a26bc", "status": "affected", "versionType": "git"}, {"version": "f01a2161577d31b14581e0db3bbbdfa963f145b6", "lessThan": "3b1d4fc3b73ea6faf008a0996ce6190c6e43efc3", "status": "affected", "versionType": "git"}, {"version": "f01a2161577d31b14581e0db3bbbdfa963f145b6", "lessThan": "a7dc30b6828c3a30252892827b12b676749f250f", "status": "affected", "versionType": "git"}, {"version": "f01a2161577d31b14581e0db3bbbdfa963f145b6", "lessThan": "a61b4db34a753bdf5c9e77a7f3d3dddd41dcfacc", "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/ethernet/netronome/nfp/nfpcore/nfp_resource.c"], "versions": [{"version": "4.11", "status": "affected"}, {"version": "0", "lessThan": "4.11", "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": "4.11", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "7.2-rc5"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/6dbd428119cb1fd1b73cf6968c711f4ea964dc8b"}, {"url": "https://git.kernel.org/stable/c/cfa119aa781c4044dab5b4c1e5864600f53a26bc"}, {"url": "https://git.kernel.org/stable/c/3b1d4fc3b73ea6faf008a0996ce6190c6e43efc3"}, {"url": "https://git.kernel.org/stable/c/a7dc30b6828c3a30252892827b12b676749f250f"}, {"url": "https://git.kernel.org/stable/c/a61b4db34a753bdf5c9e77a7f3d3dddd41dcfacc"}], "title": "nfp: Check resource mutex allocation", "x_generator": {"engine": "bippy-1.2.0"}}}}
