discovered that the InfiniBand RDMA driver in the Linux kernel did not
properly check for zero-length STAG or MR registration. A remote attacker
could possibly use this to execute arbitrary code. (CVE-2023-25775)

Yu Hao discovered that the UBI driver in the Linux kernel did not properly
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)

Manfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb)
Ethernet driver in the Linux kernel did not properly validate received
frames that are larger than the set MTU size, leading to a buffer overflow
vulnerability. An attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-45871)

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)");
