NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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

thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR

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

Then the data_vault_read() 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 ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or NULL value in data_vault.
