zephyr_cve-2021-3625

CVE-2021-3625 This repository contains a few example exploits for CVE-2021-3625. All Zephyr-based usb devices up to and including version 2.5.0 suffer from a buffer overflow allowing readout of up to 65kB. Depending on the actual device this may result of leakage of sensitive data like encryption...

CVE-2026-82961

The GPIO syscall handlers in drivers/gpio/gpiohandlers.c did not validate the pin argument supplied by a user-mode caller. zvrfygpiopinconfigure, zvrfygpiopingetconfig and zvrfygpiopininterruptconfigure verified only the device object KSYSCALLDRIVERGPIO / KSYSCALLOBJ and then passed the...

CVE-2026-82962

The Zephyr RTOS contains an out-of-bounds write vulnerability in subsys/net/l2/ethernet/ethernet.c within the ethernet_fill_header() function. The issue arises when the system attempts to prepend an Ethernet header in-place for packets that lack sufficient headroom, such as those produced by rout...

CVE-2026-82962 Out-of-bounds write in Zephyr Ethernet L2 when adding the link-layer header to a forwarded packet

ethernetfillheader in subsys/net/l2/ethernet/ethernet.c can prepend the Ethernet header in place, by pushing it into the headroom of the packet's first fragment, instead of allocating a separate header fragment. Before this fix the in-place path was selected purely from the build-time value of...

CVE-2026-82961

In Zephyr RTOS builds with CONFIG_USERSPACE=y, the GPIO syscall handlers in drivers/gpio/gpio_handlers.c fail to validate the pin argument provided by user-mode callers. While the handlers verify the device object, they pass the gpio_pin_t directly to drivers. Because the existing check is wrappe...

CVE-2026-82961 Unvalidated pin index in GPIO syscall handlers allows out-of-bounds kernel writes from user mode

The GPIO syscall handlers in drivers/gpio/gpiohandlers.c did not validate the pin argument supplied by a user-mode caller. zvrfygpiopinconfigure, zvrfygpiopingetconfig and zvrfygpiopininterruptconfigure verified only the device object KSYSCALLDRIVERGPIO / KSYSCALLOBJ and then passed the...

CVE-2026-82388

bthfphfconnect in subsys/bluetooth/host/classic/hfphf.c allocates the per-connection HFP Hands-Free object with hfphfcreate, which starts an SDP discovery by passing the object's embedded hf-sdpparam to btsdpdiscover. That call links the caller-owned parameter block into the SDP client's request...
