CVE-2026-53994

ProFTPD modsftp contains a heap-based buffer overflow reachable by an authenticated SFTP user. The fxppacketread function accepts the attacker-supplied 32-bit big-endian SFTP packet length without a minimum sanity check. A value of 0 causes an unsigned subtraction elsewhere in the read path to...

CVE-2026-10639 Use-after-free reading `net_pkt_iface()` of a sent ICMPv4 echo-reply packet in `icmpv4_handle_echo_request()`

In Zephyr's native IPv4 stack, icmpv4handleechorequest in subsys/net/ip/icmpv4.c builds an echo-reply packet reply, hands it to nettrysenddata, and then, on success, calls netstatsupdateicmpsentnetpktifacereply. nettrysenddata transfers ownership of reply to the TX path netiftryqueuetx - netiftx ...
