Overview

CVE-2026-90029 is a known-severity vulnerability. It was published on September 16, 2026.

Technical description

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

usb: storage: realtek_cr: fix use-after-free on disconnect

realtek_cr_destructor() calls timer_delete() before the chip containing

the timer is freed. The timer callback may still be running and can

rearm itself, resulting in a use-after-free.

Use timer_shutdown_sync() to wait for the callback and prevent further

rearming. Do this unconditionally because ss_en may be changed after

the timer is armed.

Move timer_setup() into init_realtek_cr() so the timer is initialized

before any failure path can invoke the destructor.

Found by static analysis.
