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":"18737a48acc87e4cbe41d6fea9a3f44eae490e24","status":"affected","versionType":"git"},{"version":"f01a2161577d31b14581e0db3bbbdfa963f145b6","lessThan":"423523f96a681428ce6e214eaf47f0d8242319de","status":"affected","versionType":"git"},{"version":"f01a2161577d31b14581e0db3bbbdfa963f145b6","lessThan":"0dbd85a8cc35c14bd26e686fa5fae8c64a7958ae","status":"affected","versionType":"git"},{"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":"5.10.265","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.216","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.183","lessThanOrEqual":"6.1.*","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","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":"5.10.265"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.11","versionEndExcluding":"5.15.216"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.11","versionEndExcluding":"6.1.183"},{"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"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/18737a48acc87e4cbe41d6fea9a3f44eae490e24"},{"url":"https://git.kernel.org/stable/c/423523f96a681428ce6e214eaf47f0d8242319de"},{"url":"https://git.kernel.org/stable/c/0dbd85a8cc35c14bd26e686fa5fae8c64a7958ae"},{"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"}}}}
