CVE-2026-16513

The Zephyr RTOS (with CONFIG_USERSPACE and CONFIG_RTIO enabled) is vulnerable to an arbitrary kernel write due to missing write validation in the z_vrfy_rtio_sqe_copy_in_get_handles() verifier within subsys/rtio/rtio_syscalls.c. The system fails to check the handle out-parameter, allowing a user-...

In the Linux kernel, the following vulnerability has been resolved: bpf: Require MEMPERCPU for percpu kptr stores mapkptrmatchtype treats permflags as the set of register type flags that a kptr field permits. Adding MEMPERCPU to that set for BPFKPTRPERCPU does not require the source register to...

prefetch-tool

Windows KASLR Prefetch Tool A proof-of-concept tool for bypassing KASLR kernel ASLR on Windows 11. Inspired by EntryBleed for Linux. This tool was developed as part of an exploit targetting Windows 11 24H2. I am not a side-channel expert at all, so this was very much new territory for me and the...

FreeBSD -- Race condition in ELF core dump segment counting

Problem Description: The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them. A process sharing the address space via rfork2 can mutate the map between the two passes,...

CVE-2026-64156

The CVE-2026-64156 vulnerability affects the Linux kernel’s netfs and AFS components. It arises when a write is skipped due to lock contention and WB_SYNC_NONE, potentially failing to re-mark the inode. The documented fix modifies netfs_write_single() to return 1 when a skip occurs and updates af...

CVE-2026-10671 User thread can re-initialize an in-use `k_pipe`, corrupting kernel wait queues (`CONFIG_USERSPACE`)

In Zephyr's kernel pipe implementation, the userspace syscall verifier zvrfykpipeinit in kernel/pipe.c used KSYSCALLOBJ which requires the kernel object to already be initialized instead of KSYSCALLOBJNEVERINIT which rejects an already-initialized object. As a result, on CONFIGUSERSPACE builds an...
