DESCRIPTION

* Information leak in Transparent Inter Process Communication (TIPC) protocol.

A logic error in TIPC protocol during socket initialization can lead to
kernel information leak. A local user could use this flaw to gain access
to sensitive information.


* CVE-2022-3628: Code execution in Broadcom FullMAC USB WiFi driver.

A missing sanity check when setting up the Broadcom FullMAC USB WiFi
driver could result in out-of-bounds access. A physically proximate
user could use this flaw to craft a malicious USB device and cause
a denial-of-service or execute arbitrary code.


* CVE-2022-3619: Denial-of-Service in Bluetooth L2CAP.

Improperly released resources in Bluetooth L2CAP when handling
fragmented frames could result in a memory leak. A remote user could
use this flaw to exhaust the kernel memory and cause a
denial-of-service.


* CVE-2023-0590: Use-after-free in network scheduler.

A race condition in net scheduler when dropping the reference of a queue
discipline object in qdisc_graft() may lead to a use-after-free. A local
user could use this flaw to cause a denial-of-service.


* CVE-2022-42895: Information disclosure in Bluetooth subsystem.

A missing sanity check when parsing a configuration request in Bluetooth
L2CAP implementation could result in out-of-bounds memory access.
A physically proximate attacker could use this flaw for information
disclosure.


* CVE-2022-3640: Use-after-free in Bluetooth subsystem.

A logic flaw in receive data path of the Bluetooth subsystem could
result in a use-after-free. A local user could use this flaw to cause
a denial-of-service or execute arbitrary code.


* CVE-2022-41849: Use-after-free when removing SMSC UFX USB device.

A race condition in the SMSC UFX USB video device driver between activating
and deactivating the device could result in a NULL-pointer dereference.
A malicious device might exploit this to cause a denial-of-service.
