Upgrade RHEL:8 kernel-debug to version 0:4.18.0-553.22.1.el8_10 or higher.
This issue was patched in RHSA-2024:7000.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-debug package and not the kernel-debug package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scpi: Fix string overflow in SCPI genpd driver
Without the bound checks for scpi_pd->name, it could result in the buffer overflow when copying the SCPI device name from the corresponding device tree node as the name string is set at maximum size of 30.
Let us fix it by using devm_kasprintf so that the string buffer is allocated dynamically.
