linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

Daniel Moghimi discovered that some Intel® Processors did not properly
clear microarchitectural state after speculative execution of various
instructions. A local unprivileged user could use this to obtain to
sensitive information. (CVE-2022-40982)

Yang Lan discovered that the GFS2 file system implementation in the Linux
kernel could attempt to dereference a null pointer in some situations. An
attacker could use this to construct a malicious GFS2 image that, when
mounted and operated on, could cause a denial of service (system crash).
(CVE-2023-3212)

It was discovered that the NET/ROM protocol implementation in the Linux
kernel contained a race condition in some situations, 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-2023-32269)

It was discovered that the NFC implementation in the Linux kernel contained
a use-after-free vulnerability when performing peer-to-peer communication
in certain conditions. A privileged attacker could use this to cause a
denial of service (system crash) or possibly expose sensitive information
(kernel memory). (CVE-2023-3863)

It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle L2CAP socket release, 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-2023-40283)

It was discovered that some network classifier implementations in the Linux
kernel contained use-after-free vulnerabilities. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2023-4128)

It was discovered that the JFS file system implementation in the Linux
kernel did not properly validate memory allocations in certain situations,
leading to a null pointer dereference vulnerability. An attacker could use
this to construct a malicious JFS image that, when mounted, could cause a
denial of service (system crash). (CVE-2023-4385)

It was discovered that the VMware VMXNET3 ethernet driver in the Linux
kernel contained a use-after-free vulnerability in certain situations. A
local attacker in a guest VM could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-4387)

It was discovered that the VMware VMXNET3 ethernet driver in the Linux
kernel did not properly handle errors in certain situations, leading to a
null pointer dereference vulnerability. A local attacker in a guest VM
could use this to cause a denial of service (system crash). (CVE-2023-4459)
