high Tenable Cloud Security Plugin ID 460556

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: net: phonet: free phonet_device after
 RCU grace period phonet_device_destroy() removes a phonet_device from the per-net device list with
 list_del_rcu(), but frees it immediately. RCU readers walking the same list can still hold a pointer to
 the object after it has been removed, leading to a slab-use-after-free. Use kfree_rcu(), matching the
 lifetime rule already used by phonet_address_del() for the same object type. (CVE-2026-53157)

Solution

Update the linux library and its related packages to version 6.1.177-1 or later.
