{"id":"CVE-2026-80940","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-80940","generatedAt":"2026-10-28T03:23:58.023Z","title":"In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: pci: fix resource leak on failed NAPI setup rtw_pci_probe() allocates PCI resources through rtw_pci_setup_resource() before it sets up NAPI.","description":"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.","published":"2026-09-11T20:18:59.000Z","lastModified":"2026-10-19T09:17:25.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00168,"percentile":0.06019,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
