| Description: | Summary:
The remote host is missing an update for the 'linux-azure, linux-intel-iotg-5.15' package(s) announced via the USN-7186-2 advisory.
Vulnerability Insight:
Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux
kernel contained a type-confusion error. A physically proximate remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2020-12351)
Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux
kernel did not properly initialize memory in some situations. A physically
proximate remote attacker could use this to expose sensitive information
(kernel memory). (CVE-2020-12352)
Andy Nguyen discovered that the Bluetooth HCI event packet parser in the
Linux kernel did not properly handle event advertisements of certain sizes,
leading to a heap-based buffer overflow. A physically proximate remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2020-24490)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
