A flaw was found in the Linux kernel's implementation of wireless drivers using the Atheros chipsets. An attacker within wireless range could send crafted traffic leading to information disclosure. A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB provided by the L1 guest to spawn/handle a nested guest . Due to improper validation of the "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB provided by the L1 guest to spawn/handle a nested guest . Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be accessible. A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl . The highest threat from this vulnerability is to data confidentiality. A flaw was found in the Linux kernel, where it incorrectly computes the access permissions of a shadow page. This issue leads to a missing guest protection page fault. A flaw was found in the Linux kernel that allows attackers to defeat an ASLR protection mechanism because it prints a kernel pointer . The highest threat from this vulnerability is to confidentiality
