Description

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: r8a66597: avoid double free of ep0_req in probe error path If usb_add_gadget_udc() fails, r8a66597_probe() jumps to err_add_udc and frees ep0_req, then falls through to clean_up2 where ep0_req is freed again when it is non-NULL. Remove the redundant free from err_add_udc and keep the cleanup in clean_up2 so the request is released exactly once. Issue found using a prototype static analysis tool and confirmed by code review.

CVE-2026-93110

A high‑severity flaw in the Linux kernel’s RDMA core module allows a use‑after‑free condition when a module is unloaded while RCU callbacks are still queued. The bug can cause kernel crashes or, in the worst case, arbitrary code execution if an attacker can trigger the callback after the module is gone.

CVE-2026-93117

A use‑after‑free flaw in the Linux kernel’s USB subsystem could be triggered when a USB device probe runs concurrently with the removal of a dynamic ID. The issue allows an attacker to potentially cause a crash or gain elevated privileges by manipulating USB devices during the probe phase.
