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-2026-17050

The experimental USB host stack allocates a per-device configuration-descriptor buffer, udev-cfgdesc, from the dedicated usbdeviceheap in usbhdevicesetconfiguration subsys/usb/host/usbhdevice.c. On three failure paths — a failed full-length GETDESCRIPTORCONFIGURATION read, a mismatch between the...

CVE-2026-15924

Zephyr's TLS socket layer in subsys/net/lib/sockets/socketstls.c keeps a single process-global array, clientcache, of cached client sessions that is shared by every TLS socket context. The functions that mutate and read it — tlssessionsave, tlssessionget, tlssessioncachereset, and the settings...

CVE-2026-15924

Zephyr RTOS TLS socket layer contains a use-after-free and double-free vulnerability in the process-global client_cache array shared across all TLS socket contexts. The root cause is that the per-socket mutex (ctx->lock) provides no mutual exclusion between different sockets concurrently acces...

CVE-2026-15893

CVE-2026-15893 affects the Zephyr RTOS IPv6 Neighbor Discovery stack. The function net_if_ipv6_calc_reachable_time() in subsys/net/ip/net_if.c computes a randomized reachable time from base_reachable_time using integer division. When the Reachable Time field of an incoming Router Advertisement is...
