  "message": "usbredir: fix infinite loop and SIGFPE with zero max_packet_size\n\nA malicious usbredir peer can send an ep_info message resetting\nmax_packet_size to 0 after bulk receiving has started. This causes:\n- infinite loop in usbredir_buffered_bulk_packet() where the splitting\n  loop increments by max_packet_size (0)\n- SIGFPE in usbredir_buffered_bulk_in_complete_ftdi() from modulo by 0\n- SIGFPE in usbredir_handle_buffered_bulk_in_data() from division by 0\n  when computing bytes_per_transfer\n\nFix by stopping and disabling bulk receiving in usbredir_ep_info() when\nmax_packet_size is set to 0.\n\nAdd post-load check, and assert() for the invariant.\n\nFixes: CVE-2026-63319\nResolves: https://gitlab.com/qemu-project/qemu/-/work_items/3995\nReported-by: Tristan @TristanInSec\nSigned-off-by: Marc-André Lureau \u003cmarcandre.lureau@redhat.com\u003e\nReviewed-by: Thomas Huth \u003cthuth@redhat.com\u003e\nMessage-ID: \u003c20260716141107.3597076-1-marcandre.lureau@redhat.com\u003e\nSigned-off-by: Thomas Huth \u003cthuth@redhat.com\u003e\n",
