During\nthe probe phase, the event device handling path returns early before\ninitializing the platform profile device (data->pp_dev), leaving it\nNULL.\n\nHowever, the PM sleep operations are registered globally for the WMI\ndriver and are triggered for both devices. When entering suspend, the\nevent device invokes bitland_mifs_wmi_suspend(), which passes the\nuninitialized data->pp_dev (NULL) into laptop_profile_get(). This leads\nto a NULL pointer dereference inside dev_get_drvdata(), causing a\nkernel Oops and halting the suspend sequence.\n\nFix this by adding a validity check for data->pp_dev in both the suspend\nand resume callbacks, safely skipping profile operations for the event\ndevice."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/platform/x86/bitland-mifs-wmi.c"],"versions":[{"version":"dc1ec4fa86b2b8bba2b6122f2b4420217b5bae9e","lessThan":"6f2cb20d8e286218d51754f06ee219d8ce754b18","status":"affected","versionType":"git"},{"version":"dc1ec4fa86b2b8bba2b6122f2b4420217b5bae9e","lessThan":"d3666875c75eb1bc8090343fa0d6fc8fb7924356","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/platform/x86/bitland-mifs-wmi.c"],"versions":[{"version":"7.1","status":"affected"},{"version":"0","lessThan":"7.1","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"7.1","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.1","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/6f2cb20d8e286218d51754f06ee219d8ce754b18"},{"url":"https://git.kernel.org/stable/c/d3666875c75eb1bc8090343fa0d6fc8fb7924356"}],"title":"platform/x86: bitland-mifs-wmi: Fix NULL pointer dereference during suspend/resume","x_generator":{"engine":"bippy-1.2.0"}}}}
