It exists that the Intel 740 frame buffer driver in the Linux kernel contained a divide by zero vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3061) 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.

Several security issues were fixed in the Linux kernel ...

An out-of-bounds write flaw was found in the Linux kernel&rsquo;s framebuffer-based console driver functionality in the way a user triggers ioctl FBIOPUT_VSCREENINFO with malicious data This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2021-33655) A vulnerability was found in the Linux kernel's ...

A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures Internal memory locations could be returned to userspace A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel ...
