{"id":"USN-6502-4","summary":"linux-azure, linux-azure-6.2, linux-azure-fde-6.2, linux-gcp, linux-gcp-6.2 vulnerabilities","details":"Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem\ndiscovered that the InfiniBand RDMA driver in the Linux kernel did not\nproperly check for zero-length STAG or MR registration. A remote attacker\ncould possibly use this to execute arbitrary code. (CVE-2023-25775)\n\nYu Hao discovered that the UBI driver in the Linux kernel did not properly\ncheck for MTD with zero erasesize during device attachment. A local\nprivileged attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-31085)\n\nManfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb)\nEthernet driver in the Linux kernel did not properly validate received\nframes that are larger than the set MTU size, leading to a buffer overflow\nvulnerability. An attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-45871)\n\nMaxim Levitsky discovered that the KVM nested virtualization (SVM)\nimplementation for AMD processors in the Linux kernel did not properly\nhandle x2AVIC MSRs. An attacker in a guest VM could use this to cause a\ndenial of service (host kernel crash). (CVE-2023-5090)\n\nIt was discovered that the SMB network file sharing protocol implementation\nin the Linux kernel did not properly handle certain error conditions,\nleading to a use-after-free vulnerability. A local attacker could use this\nto cause a denial of service (system crash) or possibly execute arbitrary\ncode.
