CVE-2024-58081

Estado: ModificadaMedia (5.5)—

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:

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().
