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_sync: reject oversized
Broadcast Announcement prepend Existing advertising instances can already hold the maximum extended
advertising payload. When hci_adv_bcast_annoucement() prepends the Broadcast Announcement service data to
that payload, the combined data may no longer fit in the temporary buffer used to rebuild the advertising
data. Reject that case before copying the existing payload and report the failure through the device log.
This keeps the existing advertising data intact and avoids overrunning the temporary buffer.

Update the linux library and its related packages to version 6.1.176-1 or later.
