Summary
It was discovered that the KVM VMX implementation in the Linux kernel did
not properly handle indirect branch prediction isolation between L1 and L2
VMs. An attacker in a guest VM could use this to expose sensitive
information from the host OS or other guest VMs. (CVE-2022-2196)
It was discovered that a use-after-free vulnerability existed in the SGI
GRU driver in the Linux kernel. A local attacker could possibly use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3424)
Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux
kernel contained an out-of-bounds write vulnerability. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2022-36280)
Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not
properly perform reference counting 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-2022-41218)
Gerald Lee discovered that the USB Gadget file system implementation in the
Linux kernel contained a race condition, leading to a use-after-free
vulnerability in some situations. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-4382)
It was discovered that the NTFS file system implementation in the Linux
kernel did not properly validate attributes in certain situations, leading
to an out-of-bounds write vulnerability. A local attacker could use this to
cause a denial of service (system crash). (CVE-2022-48423)
It was discovered that the NTFS file system implementation in the Linux
kernel did not properly validate attributes in certain situations, leading
to an out-of-bounds read vulnerability. A local attacker could possibly use
this to expose sensitive information (kernel memory). (CVE-2022-48424)
José Oliveira and Rodrigo Branco discovered that the prctl syscall
implementation in the Linux kernel did not properly protect against
indirect branch prediction attacks in some situations. A local attacker
could possibly use this to expose sensitive information. (CVE-2023-0045)
It was discovered that the KSMBD implementation in the Linux kernel did not
properly validate buffer lengths, leading to a heap-based buffer overflow.
A remote attacker could possibly use this to cause a denial of service
(system crash). (CVE-2023-0210)
It was discovered that a use-after-free vulnerability existed in the
Advanced Linux Sound Architecture (ALSA) subsystem. A local attacker could
use this to cause a denial of service (system crash). (CVE-2023-0266)
Kyle Zeng discovered that the class-based queuing discipline implementation
in the Linux kernel contained a type confusion vulnerability in some
situations. An attacker could use this to cause a denial of service (system
crash). (CVE-2023-23454)
Kyle Zeng discovered that the ATM VC queuing discipline implementation in
the Linux kernel contained a type confusion vulnerability in some
situations. An attacker could use this to cause a denial of service (system
crash). (CVE-2023-23455)
It was discovered that the RNDIS USB driver in the Linux kernel contained
an integer overflow vulnerability. A local attacker with physical access
could plug in a malicious USB device to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2023-23559)
It was discovered that the NTFS file system implementation in the Linux
kernel did not properly handle a loop termination condition, leading to an
out-of-bounds read vulnerability. A local attacker could use this to cause
a denial of service (system crash) or possibly expose sensitive
information. (CVE-2023-26606)
Wei Chen discovered that the DVB USB AZ6027 driver in the Linux kernel
contained a null pointer dereference when handling certain messages from
user space. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-28328)

Speculative execution attacks in KVM VMX
A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support…
