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.

How can CyberStrike help with CVE-2026-90029?
CyberStrike is an open-source, AI-augmented pentesting engine.
