    A use-after-free vulnerability exists in the Linux kernel's network packet handling code. When the kernel copies packet metadata during certain fragmentation operations, it fails to properly track reference counts for zero-copy transmission buffers. This causes the kernel to prematurely free buffer structures that are still in use by active network packets, leading to memory corruption. An unprivileged local user can exploit this to gain full root-level control of the system.
