This means that during removal, there is a race\ncondition where an interrupt can fire just _after_ the `power_supply`\nhandle has been freed, *but* just _before_ the corresponding\nunregistration of the IRQ handler has run.\n\nThis will lead to the IRQ handler calling `power_supply_changed()` with\na freed `power_supply` handle. Which usually crashes the system or\notherwise silently corrupts the memory...\n\nNote that there is a similar situation which can also happen during\n`probe()`; the possibility of an interrupt firing _before_ registering\nthe `power_supply` handle. This would then lead to the nasty situation\nof using the `power_supply` handle *uninitialized* in\n`power_supply_changed()`.\n\nFix this racy use-after-free by making sure the IRQ is requested _after_\nthe registration of the `power_supply` handle."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/power/supply/goldfish_battery.c"],"versions":[{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"589d4fe56713c6344cd9f8939f9c7621c85f0966","status":"affected","versionType":"git"},{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"bad8b61eb5059acd88349680e47839342dc89e94","status":"affected","versionType":"git"},{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"33751e28842bf5aee5ef7b2b8d5e456a069095cb","status":"affected","versionType":"git"},{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"77ea437faa4c06362e3ecfd2d7264eaa7ac1e82c","status":"affected","versionType":"git"},{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"4350505e82b4f972ddb788e1c712c557c38859d0","status":"affected","versionType":"git"},{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"8c89aade8335e26a6a7dcda18992d15f51943927","status":"affected","versionType":"git"},{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"0b29ffe4090a3fc7a7649de20e1eb1e53adddac7","status":"affected","versionType":"git"},{"version":"84d7b768748943db2bb658b43931fdab04c224cc","lessThan":"b2ce982e2e0c888dc55c888ad0e20ea04daf2e6b","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/power/supply/goldfish_battery.c"],"versions":[{"version":"3.9","status":"affected"},{"version":"0","lessThan":"3.9","status":"unaffected","versionType":"semver"},{"version":"5.10.252","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.202","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.165","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.128","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.75","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.14","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.4","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","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":"3.9","versionEndExcluding":"5.10.252"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"5.15.202"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.1.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.6.128"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.12.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.18.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.19.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/589d4fe56713c6344cd9f8939f9c7621c85f0966"},{"url":"https://git.kernel.org/stable/c/bad8b61eb5059acd88349680e47839342dc89e94"},{"url":"https://git.kernel.org/stable/c/33751e28842bf5aee5ef7b2b8d5e456a069095cb"},{"url":"https://git.kernel.org/stable/c/77ea437faa4c06362e3ecfd2d7264eaa7ac1e82c"},{"url":"https://git.kernel.org/stable/c/4350505e82b4f972ddb788e1c712c557c38859d0"},{"url":"https://git.kernel.org/stable/c/8c89aade8335e26a6a7dcda18992d15f51943927"},{"url":"https://git.kernel.org/stable/c/0b29ffe4090a3fc7a7649de20e1eb1e53adddac7"},{"url":"https://git.kernel.org/stable/c/b2ce982e2e0c888dc55c888ad0e20ea04daf2e6b"}],"title":"power: supply: goldfish: Fix use-after-free in power_supply_changed()","x_generator":{"engine":"bippy-1.2.0"}}}}
