"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw88: pci: fix resource leak on failed NAPI setup\n\nrtw_pci_probe() allocates PCI resources through\nrtw_pci_setup_resource() before it sets up NAPI. If\nrtw_pci_napi_init() fails, the error path jumps straight to\nerr_pci_declaim and skips rtw_pci_destroy(), leaving the PCI\nresources allocated by rtw_pci_setup_resource() behind.\n\nAdd a dedicated cleanup label for the NAPI setup failure path so probe\ndestroys the PCI resources.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing current\nmainline kernels. The tool is still under development and is not yet\npublicly available. Manual inspection confirms that the bug is still\npresent in v7.1-rc7.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have a\nsuitable rtw88 PCI board to test with, no runtime testing was able to be\nperformed."
