What to do
AI-suggested
A fix has been applied in the Linux kernel source code by adjusting the order of memory release calls. Users should update to the fixed kernel version once available.
Description
A use-after-free vulnerability in the Linux kernel's FPGA region code was fixed by moving a memory release call after an error print to prevent accessing freed memory.
