CVE-2026-53147

The CVE-2026-53147 issue affects the Linux kernel Thunderbolt XDomain handling. tb_xdp_handle_request() casts the received packet buffer to protocol-specific structs without confirming that the allocation is large enough for the target type. A peer could send a minimal XDomain packet that passes ...
