check for MTD with zero erasesize during device attachment. A local
privileged attacker could use this to cause a denial of service (system
crash). (CVE-2023-31085)

Bien Pham discovered that the netfiler subsystem in the Linux kernel
contained a race condition, leading to a use-after-free vulnerability. A
local user could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-4244)

Maxim Levitsky discovered that the KVM nested virtualization (SVM)
implementation for AMD processors in the Linux kernel did not properly
handle x2AVIC MSRs. An attacker in a guest VM could use this to cause a
denial of service (host kernel crash). (CVE-2023-5090)

It was discovered that the SMB network file sharing protocol implementation
in the Linux kernel did not properly handle certain error conditions,
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-2023-5345)

Murray McAllister discovered that the VMware Virtual GPU DRM driver in the
Linux kernel did not properly handle memory objects when storing surfaces,
leading to a use-after-free vulnerability. A local attacker in a guest VM
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-5633)");
