Description OSIDB Bzimport 2025-12-09 01:02:40 UTC 
In the Linux kernel, the following vulnerability has been resolved:

clk: clocking-wizard: Fix Oops in clk_wzrd_register_divider()

Smatch detected this potential error pointer dereference
clk_wzrd_register_divider().  If devm_clk_hw_register() fails then
it sets "hw" to an error pointer and then dereferences it on the
next line.  Return the error directly instead.
