UBUNTU-CVE-2026-29008CVE-2026-29008 0 U-Boot versions through 2026.04-rc3 contain an integer underflow vulnerability in the tcp_rx_state_machine() function. This flaw allows a network-adjacent attacker to crash the bootloader by sending a malformed TCP SYN+ACK packet with a manipulated data offset field. The vulnerability causes a negative payload length to be converted to a large unsigned integer, leading to a memcpy() call that crashes the device and may cause memory corruption when CONFIG_LMB is disabled. This prevents the device from booting properly. Join the discussion | GCVE Database | 07/08/2026, 17:17:00 UTC Added: 07/16/2026, 10:39:20 UTC |
