Description
A use-after-free vulnerability was identified and fixed in the Linux kernel's NFC subsystem, specifically in the nfc_get_local_general_bytes function. The flaw involved improper handling of reference counts leading to potential use-after-free when accessing local general bytes. The fix refactors the function to safely copy data into caller-provided buffers before releasing resources, preventing unsafe memory access.
