CVE-2026-29007 affects U-Boot (versions up to 2026.04-rc3) with CONFIG_PROT_TCP enabled. The issue is an out-of-bounds read in tcp_rx_state_machine() (net/tcp.c) triggered by a crafted IP packet whose total length and TCP data offset fields are mismatched, e.g., IP length 40 bytes and TCP header ...

CVE-2026-29007 U-Boot 2026.04-rc3 Out-of-Bounds Read in tcp_rx_state_machine via tcp.c

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...

BIT-HAPROXY-2026-33555

An issue was discovered in HAProxy before 3.3.6. The HTTP/3 parser does not check that the received body length matches a previously announced content-length when the stream is closed via a frame with an empty payload. This can cause desynchronization issues with the backend server and could be...
