EUVD-2026-92286

The system-call verifier for i3cdoccc in drivers/i3c/i3chandlers.c validated the outer struct i3ccccpayload, the broadcast ccc.data buffer and the targets.payloads array, but did not validate the per-target data buffers those array elements point at. Each struct i3cccctargetpayload carries its ow...

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...

CVE-2026-18414

The ADC API requires each driver to reject a sampling sequence whose destination buffer is too small: the buffersize field of struct adcsequence in include/zephyr/drivers/adc.h documents that "the driver must ensure that samples are not written beyond the limit and it must return an error if the...

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-...

CVE-2026-16513 Missing write validation of user-supplied handle pointer in the RTIO syscall verifier allows arbitrary kernel write

The userspace verifier zvrfyrtiosqecopyingethandles in subsys/rtio/rtiosyscalls.c subsys/rtio/rtiohandlers.c before v4.3.0 validated the RTIO object handle and the sqes input array, but not the handle out-parameter. On the first loop iteration it executed handle = sqe, storing the kernel address ...

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,...
