A maliciously provided preferred_send_size of 0x80000000 will return as smaller than max_recv_size, and then be used to set the maximum allowed alowed receive size for the next message. By sending a second message with a large value (>1420 bytes) the attacker can then achieve a heap buffer overflow. This fix replaces min_t(int, ...) with min_t(u32) Join the discussion | GCVE Database | 05/06/2026, 12:16:00 UTC Added: 07/16/2026, 10:38:58 UTC |
