| Vector | AV:L/AC:H/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.12.0-rc1-syzk
Description
The Linux kernel contained a flaw in the perf/x86/amd subsystem. A race condition involving NMI and throttle mechanisms could lead to a general protection fault (GPF) on AMD machines when the
cpuc->events[idx] becomes NULL. Specifically, the issue occurs within the amd pmu enable all() function. Syzkaller reported a GPF during testing. The vulnerability involves a null pointer dereference in the range [0x00000000000001a0-0x00000000000001a7]. The x86 pmu enable event function is implicated in the fault.Recommendations
Update to a version newer than 6.12.0-rc1-syzk.
