USN-6502-1: Linux kernel vulnerabilities

Published Nov 21, 2023
·
Updated

Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem 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)
