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.\n\n## Affected\n\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < 18737a48acc87e4cbe41d6fea9a3f44eae490e24`\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < 423523f96a681428ce6e214eaf47f0d8242319de`\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < 0dbd85a8cc35c14bd26e686fa5fae8c64a7958ae`\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < 6dbd428119cb1fd1b73cf6968c711f4ea964dc8b`\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < cfa119aa781c4044dab5b4c1e5864600f53a26bc`\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < 3b1d4fc3b73ea6faf008a0996ce6190c6e43efc3`\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < a7dc30b6828c3a30252892827b12b676749f250f`\n- `Linux >= f01a2161577d31b14581e0db3bbbdfa963f145b6 < a61b4db34a753bdf5c9e77a7f3d3dddd41dcfacc`\n- `Linux 4.11`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
