In the Linux kernel, the following vulnerability has been resolved: platform/x86: dell-smbios-wmi: Fix oops on rmmod dellsmbios initdellsmbioswmi() only registers the dellsmbioswmidriver on systems where the Dell WMI interface is supported. While exitdellsmbioswmi() unregisters it unconditionally, this leads to the following oops: [ 175.722921] ------------[ cut here ]------------ [ 175.722925] Unexpected driver unregister! [ 175.722939] WARNING: CPU: 1 PID: 3630 at drivers/base/driver.c:194 driverunregister+0x38/0x40 ... [ 175.723089] Call Trace: [ 175.723094] cleanupmodule+0x5/0xedd [dell_smbios] ... [ 175.723148] ---[ end trace 064c34e1ad49509d ]--- Make the unregister happen on the same condition the register happens to fix this.
