CVE-2026-31755

Rooted in the Linux kernel usb cdns3 gadget: when an endpoint is disabled or unconfigured, ep->desc can be NULL and __cdns3_gadget_ep_queue() may dereference it, causing a kernel crash. A patch adds a check and returns -ESHUTDOWN for unconfigured endpoints. Upstream fixes exist (commit referen...

CVE-2026-31755 usb: cdns3: gadget: fix NULL pointer dereference in ep_queue

In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: gadget: fix NULL pointer dereference in epqueue When the gadget endpoint is disabled or not yet configured, the ep-desc pointer can be NULL. This leads to a NULL pointer dereference when cdns3gadgetepqueue is called,...

CVE-2026-31718

The CVE-2026-31718 entries describe a use-after-free in ksmbd (Linux kernel in-kernel SMB3 server) triggered when a durable file handle survives a session disconnect. The root cause is an asymmetric cleanup of lock state: byte-range locks left on a freed conn->lock_list after fp->conn is nu...

CVE-2026-31709

In the Linux kernel SMB client (cifsacl), CVE-2026-31709 arises from insufficient validation of a server-provided DACL when rewriting security descriptors. The fix extends structural validation to ensure the DACL header, size, and per-ACE bounds are checked before any rewrite paths (replace_sids_...
