Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 464637

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: mtd: rawnand: serialize lock/unlock
 against other NAND operations nand_lock() and nand_unlock() call into chip->ops.lock_area/unlock_area
 without holding the NAND device lock. On controllers that implement SET_FEATURES via multiple low-level
 PIO commands, these can race with concurrent UBI/UBIFS background erase/write operations that hold the
 device lock, resulting in cmd_pending conflicts on the NAND controller. Add
 nand_get_device()/nand_release_device() around the lock/unlock operations to serialize them against all
 other NAND controller access. (CVE-2026-23434)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
