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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0dbd85a8cc35c14bd26e686fa5fae8c64a7958ae","https://git.kernel.org/stable/c/18737a48acc87e4cbe41d6fea9a3f44eae490e24","https://git.kernel.org/stable/c/3b1d4fc3b73ea6faf008a0996ce6190c6e43efc3","https://git.kernel.org/stable/c/423523f96a681428ce6e214eaf47f0d8242319de","https://git.kernel.org/stable/c/6dbd428119cb1fd1b73cf6968c711f4ea964dc8b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68328","score":0.00177,"percentile":0.07224,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
