Echo: linux: security update to 6.1.159-1

high Tenable Cloud Security Plugin ID 458856

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: usb: gadget: udc: fix use-after-free
 in usb_gadget_state_work A race condition during gadget teardown can lead to a use-after-free in
 usb_gadget_state_work(), as reported by KASAN: BUG: KASAN: invalid-access in sysfs_notify+0x2c/0xd0
 Workqueue: events usb_gadget_state_work The fundamental race occurs because a concurrent event (e.g., an
 interrupt) can call usb_gadget_set_state() and schedule gadget->work at any time during the cleanup
 process in usb_del_gadget(). Commit 399a45e5237c ("usb: gadget: core: flush gadget workqueue after device
 removal") attempted to fix this by moving flush_work() to after device_del(). However, this does not fully
 solve the race, as a new work item can still be scheduled *after* flush_work() completes but before the
 gadget's memory is freed, leading to the same use-after-free. This patch fixes the race condition robustly
 by introducing a 'teardown' flag and a 'state_lock' spinlock to the usb_gadget struct. The flag is set
 during cleanup in usb_del_gadget() *before* calling flush_work() to prevent any new work from being
 scheduled once cleanup has commenced. The scheduling site, usb_gadget_set_state(), now checks this flag
 under the lock before queueing the work, thus safely closing the race window. (CVE-2025-68282)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
