Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the KVM implementation in the Linux kernel, when
paravirtual TLB flushes are enabled in guests, the hypervisor in some
situations could miss deferred TLB flushes or otherwise mishandle them. An
attacker in a guest VM could use this to expose sensitive information (read

Paulo Bonzini discovered that the KVM hypervisor implementation in the

kernel: dos in i40e_setup_macvlans() function in drivers/net/ethernet/intel/i40e/i40e_main.c
A memory leak in the i40e_setup_macvlans() function in drivers/net/ethernet/intel/i40e/i40e_main.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering i40e_setup_channel() failures, aka CID-27d461333459.
A flaw was found in the Linux kernel. The i40e_setup_macvlans function mishandles resource cleanup. A local attacker, able to induce the error conditions, could use this flaw to crash the system. The highest threat from this vulnerability is to system availability.
Statement: This issue is rated as having Moderate impact because of the preconditions needed to trigger the error code path.
Mitigation: In order to mitigate this issue
