| Description: | Summary:
The remote host is missing an update for the 'linux-hwe-5.19' package(s) announced via the USN-5879-1 advisory.
Vulnerability Insight:
Kyle Zeng discovered that the sysctl implementation in the Linux kernel
contained a stack-based buffer overflow. A local attacker could use this to
cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-4378)
Tamas Koczka discovered that the Bluetooth L2CAP handshake implementation
in the Linux kernel contained multiple use-after-free vulnerabilities. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-42896)
It was discovered that the Bluetooth HCI implementation in the Linux kernel
did not properly deallocate memory in some situations. An attacker could
possibly use this cause a denial of service (memory exhaustion).
(CVE-2022-3619)
It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform bounds checking in some situations. A
physically proximate attacker could use this to craft a malicious USB
device that when inserted, could cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-3628)
It was discovered that a use-after-free vulnerability existed in the
Bluetooth stack in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3640)
It was discovered that the Xen netback driver in the Linux kernel did not
properly handle packets structured in certain ways. An attacker in a guest
VM could possibly use this to cause a denial of service (host NIC
availability). (CVE-2022-3643)
Tamas Koczka discovered that the Bluetooth L2CAP implementation in the
Linux kernel did not properly initialize memory in some situations. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-42895)
It was discovered that an integer overflow vulnerability existed in the
Bluetooth subsystem in the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2022-45934)
It was discovered that a race condition existed in the qdisc implementation
in the Linux kernel, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-0590)
