The helper increments the global hif_idx, writes the\nPCIe RECOG_ID register and takes a get_device() reference via\nmt7915_pci_get_hif2(), while removal only drops one reference. On non-WED\ndual-hif hardware this double-incremented hif_idx, wrote RECOG_ID twice and\nleaked a device reference. Only the call inside the WED-inactive branch is\ncorrect; drop the unconditional one. hif2 is already initialised to NULL."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/mediatek/mt76/mt7915/pci.c"],"versions":[{"version":"cacdd67812c6df824704ac078f1770188a485ff9","lessThan":"eac18fadc791928379b179e54636494b92f8cf86","status":"affected","versionType":"git"},{"version":"cacdd67812c6df824704ac078f1770188a485ff9","lessThan":"927fe8c0eb8c10295bc0018c8faa4d91f8fe98c6","status":"affected","versionType":"git"},{"version":"cacdd67812c6df824704ac078f1770188a485ff9","lessThan":"bd2e8f535ae35beb45a7fcc17ec9bbf8dc4db5fe","status":"affected","versionType":"git"},{"version":"cacdd67812c6df824704ac078f1770188a485ff9","lessThan":"249cbaa1873550689fab136b74982cbba74c4169","status":"affected","versionType":"git"},{"version":"cacdd67812c6df824704ac078f1770188a485ff9","lessThan":"29fbc5256c2d8448f084ff179d2e5092ecd1fc54","status":"affected","versionType":"git"},{"version":"cacdd67812c6df824704ac078f1770188a485ff9","lessThan":"3ae8ad277e2819a281b0e36b55633c8515c16ce7","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/mediatek/mt76/mt7915/pci.c"],"versions":[{"version":"5.18","status":"affected"},{"version":"0","lessThan":"5.18","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","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":"5.18","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/eac18fadc791928379b179e54636494b92f8cf86"},{"url":"https://git.kernel.org/stable/c/927fe8c0eb8c10295bc0018c8faa4d91f8fe98c6"},{"url":"https://git.kernel.org/stable/c/bd2e8f535ae35beb45a7fcc17ec9bbf8dc4db5fe"},{"url":"https://git.kernel.org/stable/c/249cbaa1873550689fab136b74982cbba74c4169"},{"url":"https://git.kernel.org/stable/c/29fbc5256c2d8448f084ff179d2e5092ecd1fc54"},{"url":"https://git.kernel.org/stable/c/3ae8ad277e2819a281b0e36b55633c8515c16ce7"}],"title":"wifi: mt76: mt7915: fix double hif2 init on the non-WED path","x_generator":{"engine":"bippy-1.2.0"}}}}
