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/cpcap-battery.c"],"versions":[{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"c549dd3de4b3f6e726d1b8386d40ccf7d3abdbe4","status":"affected","versionType":"git"},{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"3ff75cba1c98349a23a8f9333981deba1972cc11","status":"affected","versionType":"git"},{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"2ce2334be155bd8bad6377e99984246ce4dbd08c","status":"affected","versionType":"git"},{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"cbb9b07f88a9ef6518934c41eb3e8cf840d657d5","status":"affected","versionType":"git"},{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"f3fbe309c9bfe1aac1e2b26543e9dc4829f3275a","status":"affected","versionType":"git"},{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"2841bbb5a35c4449c0a0458e8e476b2a62f95147","status":"affected","versionType":"git"},{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"e261be6f18929f2397cd54cd583a2df624c129c1","status":"affected","versionType":"git"},{"version":"874b2adbed1253a11549cb9b7b912ab65fea9cf2","lessThan":"642f33e34b969eedec334738fd5df95d2dc42742","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/cpcap-battery.c"],"versions":[{"version":"4.13","status":"affected"},{"version":"0","lessThan":"4.13","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":"4.13","versionEndExcluding":"5.10.252"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"5.15.202"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.1.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.6.128"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.12.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.18.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.19.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c549dd3de4b3f6e726d1b8386d40ccf7d3abdbe4"},{"url":"https://git.kernel.org/stable/c/3ff75cba1c98349a23a8f9333981deba1972cc11"},{"url":"https://git.kernel.org/stable/c/2ce2334be155bd8bad6377e99984246ce4dbd08c"},{"url":"https://git.kernel.org/stable/c/cbb9b07f88a9ef6518934c41eb3e8cf840d657d5"},{"url":"https://git.kernel.org/stable/c/f3fbe309c9bfe1aac1e2b26543e9dc4829f3275a"},{"url":"https://git.kernel.org/stable/c/2841bbb5a35c4449c0a0458e8e476b2a62f95147"},{"url":"https://git.kernel.org/stable/c/e261be6f18929f2397cd54cd583a2df624c129c1"},{"url":"https://git.kernel.org/stable/c/642f33e34b969eedec334738fd5df95d2dc42742"}],"title":"power: supply: cpcap-battery: Fix use-after-free in power_supply_changed()","x_generator":{"engine":"bippy-1.2.0"}}}}
