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/bq25980_charger.c"],"versions":[{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"86f93dfb23f5bf4f285c4256a7e909d222f7de56","status":"affected","versionType":"git"},{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"16875e3b7bc9e59bfa0acaf1e43f275a6f42a30f","status":"affected","versionType":"git"},{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"0560a4b09c92e2ecaa883965cf6f9ca51c158ff9","status":"affected","versionType":"git"},{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"0de95d29d847c6217b7d5845e24a71a4aee7b359","status":"affected","versionType":"git"},{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"4aeaf03c17260415c2fdd55992f9ad4188d5455a","status":"affected","versionType":"git"},{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"03d1e4ee4e6aa6d2966e883e4ca0e5be73bf1b7c","status":"affected","versionType":"git"},{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"abea607ff2f62f4c0a5fb29f7fbdaaab163276a4","status":"affected","versionType":"git"},{"version":"5069185fc18e810715a91d80fcd075e03add600c","lessThan":"5f0b1cb41906e86b64bf69f5ededb83b0d757c27","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/bq25980_charger.c"],"versions":[{"version":"5.10","status":"affected"},{"version":"0","lessThan":"5.10","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":"5.10","versionEndExcluding":"5.10.252"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"5.15.202"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.1.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.6.128"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.12.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.18.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.19.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/86f93dfb23f5bf4f285c4256a7e909d222f7de56"},{"url":"https://git.kernel.org/stable/c/16875e3b7bc9e59bfa0acaf1e43f275a6f42a30f"},{"url":"https://git.kernel.org/stable/c/0560a4b09c92e2ecaa883965cf6f9ca51c158ff9"},{"url":"https://git.kernel.org/stable/c/0de95d29d847c6217b7d5845e24a71a4aee7b359"},{"url":"https://git.kernel.org/stable/c/4aeaf03c17260415c2fdd55992f9ad4188d5455a"},{"url":"https://git.kernel.org/stable/c/03d1e4ee4e6aa6d2966e883e4ca0e5be73bf1b7c"},{"url":"https://git.kernel.org/stable/c/abea607ff2f62f4c0a5fb29f7fbdaaab163276a4"},{"url":"https://git.kernel.org/stable/c/5f0b1cb41906e86b64bf69f5ededb83b0d757c27"}],"title":"power: supply: bq25980: Fix use-after-free in power_supply_changed()","x_generator":{"engine":"bippy-1.2.0"}}}}
