medium Tenable Cloud Security Plugin ID 460115

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: L2CAP: Fix div-by-zero in
 l2cap_le_flowctl_init() l2cap_le_flowctl_init() can cause both div-by-zero and an integer overflow since
 hdev->le_mtu may not fall in the valid range. Move MTU from hci_dev to hci_conn to validate MTU and stop
 the connection process earlier if MTU is invalid. Also, add a missing validation in read_buffer_size() and
 make it return an error value if the validation fails. Now hci_conn_add() returns ERR_PTR() as it can fail
 due to the both a kzalloc failure and invalid MTU value. divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI
