Echo: linux: security update to 6.1.159-1

high Tenable Cloud Security Plugin ID 460975

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: Bluetooth: hci_event: validate skb
 length for unknown CC opcode In hci_cmd_complete_evt(), if the command complete event has an unknown
 opcode, we assume the first byte of the remaining skb->data contains the return status. However, parameter
 data has previously been pulled in hci_event_func(), which may leave the skb empty. If so, using
 skb->data[0] for the return status uses un-init memory. The fix is to check skb->len before using
 skb->data. (CVE-2025-40301)

Solution

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