CVE-2026-10663 Use-after-free / double-free of the root USB device in the experimental USB host stack

In Zephyr's experimental USB host stack CONFIGUSBHOSTSTACK, usbhdevicedisconnect subsys/usb/host/usbhdevice.c freed the root usbdevice slab object without clearing the cached pointer ctx-root. The bus removal handler devremovedhandler subsys/usb/host/usbhcore.c decides what to tear down solely fr...

CVE-2026-10660

The CVE-2026-10660 issue affects the Zephyr Bluetooth BAP Broadcast Assistant GATT client (subsys/bluetooth/audio/bap_broadcast_assistant.c). A single static net_buf_simple buffer (att_buf, BT_ATT_MAX_ATTRIBUTE_LEN = 512) is shared across all connections; per-connection state (BUSY flag, long-rea...

CVE-2026-10659 NULL pointer dereference in Zephyr Dhara FTL disk driver on flash read error during journal resume

The Dhara flash translation layer disk driver drivers/disk/ftldhara.c implemented the dharanand callbacks so that, on a flash error, the error code was written unconditionally through the caller-supplied dharaerrort err pointer e.g. err = DHARAEECC in dharanandread, and similar in...

CVE-2026-10659

The CVE concerns Zephyr’s Dhara FTL disk driver (drivers/disk/ftl_dhara.c). On flash read errors, the driver previously wrote error codes unconditionally to a caller-supplied err pointer, and the journal-resume path forwarded NULL into dhara_nand_read(), causing a NULL dereference during disk ini...

CVE-2026-10657

Zephyr's DNS resolver detects mDNS .local queries in dnsresolvenameinternal subsys/net/lib/dns/resolve.c with memcmpstrrchrquery, '.', ".local", 7, which always reads a fixed 7 bytes from the suffix pointer.

CVE-2026-10657

The CVE-2026-10657 vulnerability affects Zephyr's DNS resolver when MDNS (CONFIG_MDNS_RESOLVER) is enabled. The code uses memcmp(strrchr(query, '.'), ".local", 7) to detect mDNS queries, reading a fixed 7 bytes from the suffix pointer. If the final label is shorter than 7 bytes (e.g., .org, .com,...
