DESCRIPTION

* CVE-2022-3524: Memory-leak in IPv6 networking.

A race condition in IPv6 networking when converting an IPv6 socket into
IPv4 could lead to a memory-leak. A local user could use this flaw to
exhaust the system's memory and cause denial-of-service.

Orabug: 34719347


* 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.

Orabug: 34951662


* Use-after-free in SCSI qla2xxx driver abort path.

A failure to properly handle some error cases can result in a
use-after-free during certain abort operations in the qla2xxx driver.
This could result in a denial-of-service, and could potentially be
exploited by a malicious user to aid in another type of attack.

Orabug: 34970763


* CVE-2022-3564: Use-after-free in Bluetooth L2CAP.

A race condition in Bluetooth L2CAP when a socket buffer is queued and
dequeued by two flows running in parallel can lead to a use-after-free.
A remote attacker could use this flaw for a denial-of-service or
for privilege escalation.

Orabug: 34719829


* CVE-2022-42896: Use-after-free in Bluetooth L2CAP.

A flaw in Bluetooth L2CAP protocol when accepting incoming connection
requests could lead to a use-after-free. A remote attacker could use
this flaw for a denial-of-service or for privilege escalation.

Orabug: 34833307


* CVE-2022-4662: Denial-of-service in USB core.

Lack of protection from nested device resets in the USB core implementation
could lead to a system crash. A local attacker could use this flaw to cause
a denial-of-service.

Orabug: 34951641


* 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.

Orabug: 34951546


* Denial-of-service when resetting two iSCSI logical units.

A race condition when resetting concurrently two iSCSI Logical Unit Numbers
(LUNs) could lead to a denial-of-service.
