CVE-2024-50163 is a medium-severity vulnerability in the Linux kernel related to the bpf_redirect flags used in BPF (Berkeley Packet Filter) redirect paths. The issue arises because internal and UAPI bpf_redirect flags overlap numerically, causing confusion between SKB and XDP redirect paths. This overlap can lead to kernel crashes when certain redirect functions are used sequentially. The vulnerability has been addressed by separating the flag definitions and ensuring no overlap, along with adding compile-time checks to prevent reintroduction of the issue.
