CVE-2025-38635 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: clk: davinci: Add NULL check in davinci_lpsc_clk_register() devm_kasprintf() returns NULL when memory allocation fails. Currently, davinci_lpsc_clk_register() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue and ensuring no resources are left allocated.. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
