Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.17.8. Affected by this issue is the function of_genpd_add_provider_onecell of the component pmdomain. The manipulation with an unknown input leads to a memory leak vulnerability. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: pmdomain: arm: scmi: Fix genpd leak on provider registration failure If of_genpd_add_provider_onecell() fails during probe, the previously created generic power domains are not removed, leading to a memory leak and potential kernel crash later in genpd_debug_add(). Add proper error handling to unwind the initialized domains before returning from probe to ensure all resources are correctly released on failure.
