CVSSv4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local privileged user to cause a use-after-free condition.

The vulnerability exists due to use-after-free in GHL poke timer handling in the hid-sony driver when handling driver unbind while a GHL poke URB is in flight. A local privileged user can trigger a driver unbind while the GHL poke URB is in flight to cause a use-after-free condition.

The issue affects Guitar Hero Live dongles, where a URB completion can re-arm the timer after driver teardown.
