  "description": "In the Linux kernel, the following vulnerability has been resolved:  clk: eswin: Zero-initialize stack-allocated clk_init_data  eswin_clk_register_pll() and eswin_register_clkdiv() declare a struct clk_init_data on the stack and only initialize some of its fields (parent_data respectively parent_hws). clk_core_populate_parent_map() checks parent_names first and parent_data second before falling back to parent_hws, so leftover stack garbage in the uninitialized fields hijacks parent resolution and the clk core dereferences a bogus pointer:    Unable to handle kernel NULL pointer dereference at virtual address 000000000000000c   Oops [#1]   epc : __clk_register\u002B0x31a/0x7f0   [\u003Cffffffff805dc774\u003E] __clk_register\u002B0x31a/0x7f0   [\u003Cffffffff805dcd76\u003E] devm_clk_hw_register\u002B0x2a/0x94   [\u003Cffffffff805e319a\u003E] eswin_register_clkdiv\u002B0x80/0xd0   [\u003Cffffffff805e34a0\u003E] eswin_clk_register_clks\u002B0x162/0x1a0   [\u003Cffffffff805e3736\u003E] eic7700_clk_probe\u002B0x146/0x180   [\u003Cffffffff8065d23c\u003E] platform_probe\u002B0x3c/0x7a  Observed on EIC7700 hardware (with the driver backported to a 6.17 tree); whether the bug triggers depends entirely on what the stack happens to contain when the registration helpers run.
