DESCRIPTION

* 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-2022-42895: 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-2022-41850: Use-after-free in Roccat support driver.

A race condition in Roccat support driver may lead to a
read-after-free. A local user could use this flaw to gain
sensitive information as a part of another type of attack.


* 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.


* Improved update to CVE-2022-1184: Use-after-free in ext4 filesystem.

A flaw in ext4 filesystem when mounting and operating on a corrupted
image could lead to a use-after-free. A local user could use this flaw
to cause a denial-of-service or elevate privileges on the system.


* CVE-2022-3623: Information disclosure in hugetlb.

A race condition in hugetlb when multiple threads are looking up
CONT-PTE/PMD pages could lead to page table inconsistencies. A local
attacker could use this to cause a denial-of-service or expose sensitive
information.


* 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-2022-3543: Denial-of-service in Unix domain sockets.

Improperly released resources in the AF_UNIX sockets when closing
sockets with unconsumed out-of-band buffers could lead to a memory leak.
A local user could use this flaw to exhaust kernel memory and cause de
denial-of-service.


* 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-2022-47940: Out-of-bounds memory access in SMB2.

Improper validation of user-supplied data in SMB2 when handling
SMB2_WRITE commands may lead to an out-of-bounds memory read. A remote
attacker could use this flaw to disclose sensitive information from the
kernel memory.


* 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-2022-41849: 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.
