Vulnerability from variot
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. Linux Kernel Is vulnerable to an out-of-bounds write.Information is tampered with and denial of service (DoS) It may be put into a state. KVM is one of the kernel-based virtual machines. This vulnerability could result in an out-of-bounds write. Description:

========================================================================== Ubuntu Security Notice USN-4983-1 June 03, 2021
linux-oem-5.10 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33200)
Piotr Krysiuk and Benedict Schlueter discovered that the eBPF implementation in the Linux kernel performed out of bounds speculation on pointer arithmetic. A local attacker could use this to expose sensitive information. (CVE-2021-29155)
Piotr Krysiuk discovered that the eBPF implementation in the Linux kernel did not properly prevent speculative loads in certain situations. A local attacker could use this to expose sensitive information (kernel memory). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-3501)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: linux-image-5.10.0-1029-oem 5.10.0-1029.30 linux-image-oem-20.04 5.10.0.1029.30 linux-image-oem-20.04b 5.10.0.1029.30
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well

"data": "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. Linux Kernel Is vulnerable to an out-of-bounds write.Information is tampered with and denial of service (DoS) It may be put into a state. KVM is one of the kernel-based virtual machines. This vulnerability could result in an out-of-bounds write.

A local attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2021-33200)\n\nPiotr Krysiuk and Benedict Schlueter discovered that the eBPF\nimplementation in the Linux kernel performed out of bounds speculation on\npointer arithmetic. A local attacker could use this to expose sensitive\ninformation. (CVE-2021-29155)\n\nPiotr Krysiuk discovered that the eBPF implementation in the Linux kernel\ndid not properly prevent speculative loads in certain situations. A local\nattacker could use this to expose sensitive information (kernel memory). A local attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2021-3501)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 20.04 LTS:\n linux-image-5.10.0-1029-oem 5.10.0-1029.30\n linux-image-oem-20.04 5.10.0.1029.30\n linux-image-oem-20.04b 5.10.0.1029.30\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well",
