CVE-2021-46995 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: can: mcp251xfd: mcp251xfd_probe(): fix an error pointer dereference in probe When we converted this code to use dev_err_probe() we accidentally removed a return. It means that if devm_clk_get() it will lead to an Oops when we call clk_get_rate() on the next line.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
