5.5 MEDIUM — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Description

In the Linux kernel, the following vulnerability has been resolved: can: usb: f81604: correctly anchor the urb in the read bulk callback When submitting an urb, that is using the anchor pattern, it needs to be anchored before submitting it otherwise it could be leaked if usb_kill_anchored_urbs() is called. This logic is correctly done elsewhere in the driver, except in the read bulk callback so do that here also.

Affected configurations

• linux linux kernel (>= 6.5.1 < 6.6.130) • linux linux kernel (>= 6.7 < 6.12.77) • linux linux kernel (>= 6.13 < 6.18.17) • linux linux kernel (>= 6.19 < 6.19.7) • linux linux kernel 6.5 • linux linux kernel 7.0
