Severity: 
High
Description: 

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* Kernel: KVM: OOB memory access via mmio ring buffer (CVE-2019-14821)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* KEYS: prevent creating a different user's keyrings RHEL-6.10 (BZ#1537371)

* BUG: unable to handle kernel NULL pointer dereference at (null) (BZ#1733760)

* long I/O stalls with bnx2fc from not masking off scope bits of retry delay value (BZ#1749512)

CVE-2019-14821
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.
