CVE-2024-58065

The CVE-2024-58065 issue concerns the Linux kernel component clk: mmp: pxa1908-apbc. Root cause: the NULL vs IS_ERR() check was incorrect because devm_kzalloc() returns NULL on error, not an error pointer. Die to this, a NULL check fix was applied to properly distinguish allocation failures. The ...
