"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: endpoint: pci-epf-test: Make use of cached 'epc_features' in pci_epf_test_core_init()\n\nInstead of getting the epc_features from pci_epc_get_features() API, use\nthe cached pci_epf_test::epc_features value to avoid the NULL check. Since\nthe NULL check is already performed in pci_epf_test_bind(), having one more\ncheck in pci_epf_test_core_init() is redundant and it is not possible to\nhit the NULL pointer dereference.\n\nAlso with commit a01e7214bef9 (\"PCI: endpoint: Remove \"core_init_notifier\"\nflag\"), 'epc_features' got dereferenced without the NULL check, leading to\nthe following false positive Smatch warning:\n\n drivers/pci/endpoint/functions/pci-epf-test.c:784 pci_epf_test_core_init() error: we previously assumed 'epc_features' could be null (see line 747)\n\nThus, remove the redundant NULL check and also use the epc_features::\n{msix_capable/msi_capable} flags directly to avoid local variables.\n\n[kwilczynski: commit log]"
