https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265147 Bug ID: 265147 Summary: bhnd: fix potential resource leak in bhnd_usb_attach() Product: Base System Version: Unspecified Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: niejianglei2021@163.com Created attachment 235186 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D235186&action= =3Dedit a possible patch bhnd_usb_attach() allocates PMU for dev with bhnd_alloc_pmu(). When bhnd_request_ext_rsrc() fails, relevant resource is not released, which will lead to a resource leak. We should release the relevant resource with bhnd_release_pmu() when bhnd_request_ext_rsrc() fails to avoid the resource leak. --=20 You are receiving this mail because: You are the assignee for the bug.=
