CVE-2022-0435 8.8 - High - March 25, 2022

A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.

Memory Corruption

A use-after-free flaw was found in the Linux kernels FUSE filesystem in the way a user triggers write()

CVE-2022-1011 7.8 - High - March 18, 2022

Dangling pointer

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values

CVE-2022-0847 7.8 - High - March 10, 2022

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

Improper Initialization

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization

CVE-2021-3656 8.8 - High - March 04, 2022

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-2021-3609 7 - High - March 03, 2022

.A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.

Race Condition

A vulnerability was found in the Linux kernels cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function

CVE-2022-0492 7.8 - High - March 03, 2022

A vulnerability was found in the Linux kernels cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.

AuthZ

A flaw was found in the Linux kernel in versions before 5.12

CVE-2021-3501 7.1 - High - May 06, 2021

A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.
