{"id":"USN-6503-1","summary":"linux, linux-aws, linux-laptop, linux-lowlatency, linux-oem-6.5, linux-oracle, linux-raspi, linux-starfive vulnerabilities","details":"Yu 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\nBien Pham discovered that the netfiler subsystem in the Linux kernel\ncontained a race condition, leading to a use-after-free vulnerability. A\nlocal user could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-4244)\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. (CVE-2023-5345)\n\nMurray McAllister discovered that the VMware Virtual GPU DRM driver in the\nLinux kernel did not properly handle memory objects when storing surfaces,\nleading to a use-after-free vulnerability. A local attacker in a guest VM\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code.
