Vulnerability from github – Published: 2024-05-03 18:30 – Updated: 2026-06-01 18:31

Details

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.

Severity

5.5 (Medium)
