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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/realtek/rtw88/pci.c"],"versions":[{"version":"d0bcb10e7b94861c714ab1e62c98bf8abaa37527","lessThan":"481fff9bda01720c70b19fb260808145a3f21594","status":"affected","versionType":"git"},{"version":"d0bcb10e7b94861c714ab1e62c98bf8abaa37527","lessThan":"34a505071d1ffc5ebf3dc3cd16d2a12b044bcc84","status":"affected","versionType":"git"},{"version":"d0bcb10e7b94861c714ab1e62c98bf8abaa37527","lessThan":"b1596e212ab1739930b25b9d3daf6b5cd307b537","status":"affected","versionType":"git"},{"version":"d0bcb10e7b94861c714ab1e62c98bf8abaa37527","lessThan":"e779df4806cd29cbcca5c9dc0a1073662c76b889","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/realtek/rtw88/pci.c"],"versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"6.12.109","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.50","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.4","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.12.109"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.18.50"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.2.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/481fff9bda01720c70b19fb260808145a3f21594"},{"url":"https://git.kernel.org/stable/c/34a505071d1ffc5ebf3dc3cd16d2a12b044bcc84"},{"url":"https://git.kernel.org/stable/c/b1596e212ab1739930b25b9d3daf6b5cd307b537"},{"url":"https://git.kernel.org/stable/c/e779df4806cd29cbcca5c9dc0a1073662c76b889"}],"title":"wifi: rtw88: pci: fix resource leak on failed NAPI setup","x_generator":{"engine":"bippy-1.2.0"}}}}
