GHSA-6F4M-GF33-R3P4

Vulnerability from github – Published: 2026-08-15 06:32 – Updated: 2026-08-15 06:32

Details

In the Linux kernel, the following vulnerability has been resolved:

Input: ims-pcu - fix use-after-free and double-free in disconnect

ims_pcu_disconnect() only intended to perform cleanup when the primary (control) interface is unbound. However, it currently relies on the interface class to distinguish between control and data interfaces. A malicious device could present a data interface with the same class as the control interface, leading to premature cleanup and potential use-after-free or double-free.

Switch to verifying that the interface being disconnected is indeed the control interface.
