Summary
CVE-2022-48703 affecting package kernel 5.15.200.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

thermal/int340xthermal: handle datavault when the value is ZEROSIZEPTR

In some case, the GDDV returns a package with a buffer which has zero length. It causes that kmemdup() returns ZEROSIZEPTR (0x10).

Then the datavaultread() got NULL point dereference problem when accessing the 0x10 value in data_vault.

[ 71.024560] BUG: kernel NULL pointer dereference, address: 0000000000000010

This patch uses ZEROORNULLPTR() for checking ZEROSIZEPTR or NULL value in datavault.
