SUSE-SU-2021:2646-1 advisory.\n\n - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222 4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)\n\n - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation. (CVE-2021-22543)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.

The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read\n the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's\n memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222\n 4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)\n\n - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass\n RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users\n with the ability to start and control a VM to read/write random pages of memory and can result in local\n privilege escalation. (CVE-2021-22543)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's IEEE 802.15.4 wireless networking\n subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the\n system. The highest threat from this vulnerability is to system availability.

the SUSE-SU-2021:2756-1 advisory.\n\n - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222 4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)\n\n - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest.

USN-5071-1 advisory.\n\n - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the virt_ext field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) 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. (CVE-2021-3656)\n\n - An issue was discovered in the Linux kernel before 5.9. arch/x86/kvm/svm/sev.c allows attackers to cause a denial of service (soft lockup) by triggering destruction of a large SEV VM (which requires unregistering many encrypted regions), aka CID-7be74942f184. (CVE-2020-36311)\n\n - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3612)\n\n - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) 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. This flaw affects Linux kernel versions prior to 5.14-rc7. (CVE-2021-3653)\n\n - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation. (CVE-2021-22543)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2021-09-09T00:00:00",

The flaw occurs when\n processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested\n guest (L2). Due to improper validation of the virt_ext field, this issue could allow a malicious L1 to\n disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the\n L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire\n system, leak of sensitive data or potential guest-to-host escape. (CVE-2021-3656)\n\n - An issue was discovered in the Linux kernel before 5.9. arch/x86/kvm/svm/sev.c allows attackers to cause a\n denial of service (soft lockup) by triggering destruction of a large SEV VM (which requires unregistering\n many encrypted regions), aka CID-7be74942f184. (CVE-2020-36311)\n\n - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions\n before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the\n system or possibly escalate their privileges on the system. The highest threat from this vulnerability is\n to confidentiality, integrity, as well as system availability. (CVE-2021-3612)\n\n - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when\n processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested\n guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to\n enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest\n would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak\n of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to\n 5.14-rc7. (CVE-2021-3653)\n\n - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass\n RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users\n with the ability to start and control a VM to read/write random pages of memory and can result in local\n privilege escalation.
