A flaw was found in the Linux kernel. Specifically, within the Berkeley Packet Filter (BPF) component, an error in the `cgroup_storage_get_next_key()` function's end-of-list detection mechanism can cause the system to read from an invalid memory location. This incorrect handling may lead to internal map fields being copied to userspace, resulting in information disclosure.
