Vulnerability Details CVE-2024-58081
In the Linux kernel, the following vulnerability has been resolved:
clk: mmp2: call pm_genpd_init() only after genpd.name is set
Setting the genpd's struct device's name with dev_set_name() is
happening within pm_genpd_init(). If it remains NULL, things can blow up
later, such as when crafting the devfs hierarchy for the power domain:
Unable to handle kernel NULL pointer dereference at virtual address 00000000 when read
...
Call trace:
strlen from start_creating+0x90/0x138
start_creating from debugfs_create_dir+0x20/0x178
debugfs_create_dir from genpd_debug_add.part.0+0x4c/0x144

Bisecting tracks this crash back to commit 899f44531fe6 ("pmdomain: core:
Add GENPD_FLAG_DEV_NAME_FW flag"), which exchanges use of genpd->name
with dev_name(&genpd->dev) in genpd_debug_add.part().
