clk: Fix clk_core_get NULL dereference
CWE ID: N/A
Base Score (CVSS): N/A
CVE: CVE-2024-27038
Descrizione: In the Linux kernel, the following vulnerability has been resolved: clk: Fix clk_core_get deref reference It is possible for clk_core_get to dereference to NULL in the following sequence: clk_core_get() of_clk_get_hw_from_clkspec() __of_clk_get_hw_from_provider() __clk_get_hw() __clk_get_hw() can return NULL, which is derefered by clk_core_get() at hw->core. Prior to commit dde4eff47c82 (“clk: Look for parents with clkdev based clk_lookups”) the check IS_ERR_OR_NULL() was performed which would have caught the NULL. Reading the description of this function, it discusses returning NULL but that cannot be the case at the moment. Update the function to check for hw before dereferencing it and return NULL if hw is NULL.
