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."}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.4,"baseSeverity":"HIGH"}}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/power/supply/rt9455_charger.c"],"versions":[{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"d4e2e3c3caa26b93aa9f36d0a6824b584e2a8dfc","status":"affected","versionType":"git"},{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"62d753b916bd500bb269b7078cdab73198ab4718","status":"affected","versionType":"git"},{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"a39f8f06216f73ef40e71e2fe4ad071964c1fd36","status":"affected","versionType":"git"},{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"af261f218a7606f93d2c786353d60bb4feb56ef0","status":"affected","versionType":"git"},{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"2178dc65d45e2f7bcaa8af8d80d100419bdab251","status":"affected","versionType":"git"},{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"64e15155095f39f4dec9b4659da1238ef8fc54d4","status":"affected","versionType":"git"},{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"721449a15170fc5f028a7576d7f65b9f60d53482","status":"affected","versionType":"git"},{"version":"e86d69dd786e94046b8f5be7df1b9a8226a40b2a","lessThan":"e2febe375e5ea5afed92f4cd9711bde8f24ee6d2","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/rt9455_charger.c"],"versions":[{"version":"4.2","status":"affected"},{"version":"0","lessThan":"4.2","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":"4.2","versionEndExcluding":"5.10.252"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"5.15.202"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.1.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.6.128"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.12.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.18.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.19.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d4e2e3c3caa26b93aa9f36d0a6824b584e2a8dfc"},{"url":"https://git.kernel.org/stable/c/62d753b916bd500bb269b7078cdab73198ab4718"},{"url":"https://git.kernel.org/stable/c/a39f8f06216f73ef40e71e2fe4ad071964c1fd36"},{"url":"https://git.kernel.org/stable/c/af261f218a7606f93d2c786353d60bb4feb56ef0"},{"url":"https://git.kernel.org/stable/c/2178dc65d45e2f7bcaa8af8d80d100419bdab251"},{"url":"https://git.kernel.org/stable/c/64e15155095f39f4dec9b4659da1238ef8fc54d4"},{"url":"https://git.kernel.org/stable/c/721449a15170fc5f028a7576d7f65b9f60d53482"},{"url":"https://git.kernel.org/stable/c/e2febe375e5ea5afed92f4cd9711bde8f24ee6d2"}],"title":"power: supply: rt9455: Fix use-after-free in power_supply_changed()","x_generator":{"engine":"bippy-1.2.0"}}}}
