Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

A race condition was discovered in ext4writeinlinedataend in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel through 5.13.13.(CVE-2021-40490)

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)

An issue was discovered in Linux: KVM through Improper handling of VMIO|VMPFNMAP 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)
