CVE-2026-10642 Unbounded TX busy-loop DoS in Zephyr PL011 UART driver under CTS hardware flow control

The Zephyr PL011 UART driver drivers/serial/uartpl011.c contains an unbounded software loop in pl011irqtxenable that repeatedly invokes the interrupt-driven application callback while the TX interrupt mask bit PL011IMSCTXIM is set, to work around the controller's level-transition TX-interrupt...

Netty is an asynchronous, event-driven network application framework. From 4.2.0.Final to 4.2.13.Final , Netty's epoll transport fails to detect and close TCP connections that receive a RST after being half-closed, leading to stale channels that are never cleaned up and, in some code paths, a 100...

CVE-2022-42324

Oxenstored 32-31 bit integer truncation issues Integers in Ocaml are 63 or 31 bits of signed precision. The Ocaml Xenbus library takes a C uint32t out of the ring and casts it directly to an Ocaml integer. In 64-bit Ocaml builds this is fine, but in 32-bit builds, it truncates off the most...
