{"id":"CVE-2026-68328","summary":"nfp: Check resource mutex allocation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnfp: Check resource mutex allocation\n\nnfp_cpp_resource_find() allocates a CPP mutex handle for the matching\nresource-table entry and then reports success.  nfp_resource_try_acquire()\nimmediately passes that handle to nfp_cpp_mutex_trylock().\n\nHowever, nfp_cpp_mutex_alloc() returns NULL on failure.  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.","modified":"2026-08-21T03:30:46.211728443Z","published":"2026-08-10T12:03:04.560Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68328.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0dbd85a8cc35c14bd26e686fa5fae8c64a7958ae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/18737a48acc87e4cbe41d6fea9a3f44eae490e24"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3b1d4fc3b73ea6faf008a0996ce6190c6e43efc3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/423523f96a681428ce6e214eaf47f0d8242319de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6dbd428119cb1fd1b73cf6968c711f4ea964dc8b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a61b4db34a753bdf5c9e77a7f3d3dddd41dcfacc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a7dc30b6828c3a30252892827b12b676749f250f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cfa119aa781c4044dab5b4c1e5864600f53a26bc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68328.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68328"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f01a2161577d31b14581e0db3bbbdfa963f145b6"},{"fixed":"18737a48acc87e4cbe41d6fea9a3f44eae490e24"},{"fixed":"423523f96a681428ce6e214eaf47f0d8242319de"},{"fixed":"0dbd85a8cc35c14bd26e686fa5fae8c64a7958ae"},{"fixed":"6dbd428119cb1fd1b73cf6968c711f4ea964dc8b"},{"fixed":"cfa119aa781c4044dab5b4c1e5864600f53a26bc"},{"fixed":"3b1d4fc3b73ea6faf008a0996ce6190c6e43efc3"},{"fixed":"a7dc30b6828c3a30252892827b12b676749f250f"},{"fixed":"a61b4db34a753bdf5c9e77a7f3d3dddd41dcfacc"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68328.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.11.0"},{"fixed":"5.10.265"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.216"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.183"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68328.json"}}],"schema_version":"1.9.0"}
