If the chip write\noperation returns an error other than -EOPNOTSUPP, the code jumps to the\nput label, which calls put_device(hdev). If this drops the final reference,\nthe device is freed. When the function then returns, the guard cleanup\nfunction runs and attempts to unlock the freed mutex.\n\nUse scoped_guard() instead of guard() to avoid the problem."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/hwmon/hwmon.c"],"versions":[{"version":"3ad2a7b9b15d5072139a20be84adb36776eb6c9b","lessThan":"8afab57bcdbc2186f325972e777880ac5a220f4f","status":"affected","versionType":"git"},{"version":"3ad2a7b9b15d5072139a20be84adb36776eb6c9b","lessThan":"01dd8b4fc2cf83c66565c0f382fb1841e9000a89","status":"affected","versionType":"git"},{"version":"3ad2a7b9b15d5072139a20be84adb36776eb6c9b","lessThan":"354ccc99b2dc8ba0cf6d4de34e520bcf6ecca5c2","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/hwmon/hwmon.c"],"versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc3","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":"6.18","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.3-rc3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/8afab57bcdbc2186f325972e777880ac5a220f4f"},{"url":"https://git.kernel.org/stable/c/01dd8b4fc2cf83c66565c0f382fb1841e9000a89"},{"url":"https://git.kernel.org/stable/c/354ccc99b2dc8ba0cf6d4de34e520bcf6ecca5c2"}],"title":"hwmon: Fix potential UAF in pec_store","x_generator":{"engine":"bippy-1.2.0"}}}}
