If rtw_pci_napi_init() fails, the error path jumps straight to err_pci_declaim and skips rtw_pci_destroy(), leaving the PCI resources allocated by rtw_pci_setup_resource() behind.</p> <p>Add a dedicated cleanup label for the NAPI setup failure path so probe destroys the PCI resources.</p> <p>The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing current mainline kernels. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1-rc7.</p> <p>An x86_64 allyesconfig build showed no new warnings. As we do not have a suitable rtw88 PCI board to test with, no runtime testing was able to be performed.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>wifi: rtw88: pci: fix resource leak on failed NAPI setup</p> <p>rtw_pci_probe() allocates PCI resources through rtw_pci_setup_resource() before it sets up NAPI.
