- Details
-
In the Linux kernel, the following vulnerability has been resolved:
platform/x86/intel/pmt: fix a crashlog NULL pointer access
Usage of the intelpmtread() for binary sysfs, requires a pcidev. The current use of the endpoint value is only valid for telemetry endpoint usage.
Without the ep, the crashlog usage causes the following NULL pointer exception:
BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: Oops: 0000 [#1] SMP NOPTI RIP: 0010:intelpmtread+0x3b/0x70 [pmtclass] Code: Call Trace: <TASK> ? sysfskfbinread+0xc0/0xe0 kernfsfopreaditer+0xac/0x1a0 vfsread+0x26d/0x350 ksysread+0x6b/0xe0 _x64sysread+0x1d/0x30 x64syscall+0x1bc8/0x1d70 dosyscall64+0x6d/0x110
Augment struct intelpmtentry with a pointer to the pcidev to avoid the NULL pointer exception.
