Record from OSV · Published March 1, 2024

In the Linux kernel, the following vulnerability has been resolved: platform/x86: dell-smbios-wmi: Fix oops on rmmod dell_smbios init_dell_smbios_wmi() only registers the dell_smbios_wmi_driver on systems where the Dell WMI interface is supported. While exit_dell_smbios_wmi() 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 driver_unregister+0x38/0x40 ... [ 175.723089] Call Trace: [ 175.723094] cleanup_module+0x5/0xedd [dell_smbios] ... [ 175.723148] ---[ end trace 064c34e1ad49509d ]--- Make the unregister happen on the same condition the register happens to fix this.
