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. Keep the old behavior of\njust printing a warning in case of any failures during the IRQ request\nand finishing the probe successfully."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/power/supply/sbs-battery.c"],"versions":[{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"ca7dd71773e4e050b0fb98768b7eae60f8d1f38b","status":"affected","versionType":"git"},{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"f1f472b14ad56104ba228b8fbec60d5b21829913","status":"affected","versionType":"git"},{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"8010b745b436c3e1ca5dd960aa29fa3e0f6d8841","status":"affected","versionType":"git"},{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"2078830c32d1e49ac942c6f8c21f35c806ae5e94","status":"affected","versionType":"git"},{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"82d3eb97a976c9d56bb92b241397610e57a9c629","status":"affected","versionType":"git"},{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"861dda7a9074c0ff67788928165ae39d7f647491","status":"affected","versionType":"git"},{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"14d4dee5d8fb361bfff275832087254beab66d72","status":"affected","versionType":"git"},{"version":"d2cec82c28802da31596b395ad292cb8f132fd63","lessThan":"8d59cf3887fbabacef53bfba473e33e8a8d9d07b","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/sbs-battery.c"],"versions":[{"version":"4.9","status":"affected"},{"version":"0","lessThan":"4.9","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":"4.9","versionEndExcluding":"5.10.252"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.15.202"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.1.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.6.128"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.12.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.18.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.19.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ca7dd71773e4e050b0fb98768b7eae60f8d1f38b"},{"url":"https://git.kernel.org/stable/c/f1f472b14ad56104ba228b8fbec60d5b21829913"},{"url":"https://git.kernel.org/stable/c/8010b745b436c3e1ca5dd960aa29fa3e0f6d8841"},{"url":"https://git.kernel.org/stable/c/2078830c32d1e49ac942c6f8c21f35c806ae5e94"},{"url":"https://git.kernel.org/stable/c/82d3eb97a976c9d56bb92b241397610e57a9c629"},{"url":"https://git.kernel.org/stable/c/861dda7a9074c0ff67788928165ae39d7f647491"},{"url":"https://git.kernel.org/stable/c/14d4dee5d8fb361bfff275832087254beab66d72"},{"url":"https://git.kernel.org/stable/c/8d59cf3887fbabacef53bfba473e33e8a8d9d07b"}],"title":"power: supply: sbs-battery: Fix use-after-free in power_supply_changed()","x_generator":{"engine":"bippy-1.2.0"}}}}
