| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-05-26 | CVE-2021-22543 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products 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. | 7.8 |
| 2021-03-23 | CVE-2021-20219 | Unspecified vulnerability in Linux Kernel A denial of service vulnerability was found in n_tty_receive_char_special in drivers/tty/n_tty.c of the Linux kernel. | 5.5 |
| 2021-03-22 | CVE-2021-28972 | Classic Buffer Overflow vulnerability in multiple products In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. | 6.7 |
| 2021-02-23 | CVE-2021-20194 | There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y , CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). | 7.8 |
| 2020-12-15 | CVE-2020-27777 | A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. | 6.7 |
| 2020-09-03 | CVE-2020-10720 | Use After Free vulnerability in Linux Kernel A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. | 5.5 |
| 2020-05-27 | CVE-2019-20806 | NULL Pointer Dereference vulnerability in Linux Kernel An issue was discovered in the Linux kernel before 5.2. | 4.4 |
| 2020-04-10 | CVE-2020-11669 | An issue was discovered in the Linux kernel before 5.2 on the powerpc platform. | 5.5 |
| 2020-01-31 | CVE-2019-3016 | Race Condition vulnerability in Linux Kernel In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. | 4.7 |
| 2019-08-19 | CVE-2018-20976 | Use After Free vulnerability in Linux Kernel An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. | 7.8 |
