Issue Overview:
A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)
An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel’s KVM hypervisor handled the ‘KVM_GET_EMULATED_CPUID’ ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the ‘/dev/kvm’ device could use this flaw to crash the system, resulting in a denial of service. (CVE-2019-19332 )
