| Vector | AV:L/AC:H/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.0+ #3
Description
The Linux kernel contains a race condition within the macintosh/mac hid subsystem, specifically in the
mac hid toggle emumouse() function. This issue arises when multiple processes concurrently write to the mac-hid emulation sysctl. The race condition occurs because both processes read the initial value of old val before either has a chance to register the input handler, leading to a double addition to the list. The warning message observed during testing indicates a double list add with the same handler. The root cause is that the read of old val occurs outside the mutex lock region.Recommendations
Update to a version newer than 6.6.0+ #3.
