CVE-2023-53572
In the Linux kernel, the following vulnerability has been resolved: clk: imx: scu: use _safe list iterator to avoid a use after free This loop is freeing "clk" so it needs to use list_for_each_entry_safe().
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
