EUVD-2026-42332

U-Boot through 2026.04-rc3 contains an integer underflow vulnerability in the tcprxstatemachine function net/tcp.c that allows a network-adjacent attacker to crash the bootloader by sending a malformed TCP SYN+ACK packet with a manipulated data offset field causing payloadlen to become negative...

EUVD-2026-42328

U-Boot through 2026.04-rc3 contains an out-of-bounds read vulnerability in tcprxstatemachine net/tcp.c when CONFIGPROTTCP is enabled, allowing remote attackers to read beyond TCP segment boundaries by crafting a malicious packet with a mismatched IP total length and TCP data offset field. Attacke...
