UBUNTU-CVE-2025-38583
In the Linux kernel, the following vulnerability has been resolved: clk: xilinx: vcu: unregister pll_post only if registered correctly If registration of pll_post is failed, it will be set to NULL or ERR, unregistering same will fail with following call trace: Unable to handle kernel NULL pointer dereference at virtual address 008 pc : clk_hw_unregister+0xc/0x20 lr : clk_hw_unregister_fixed_factor+0x18/0x30 sp : ffff800011923850 ...
