CVE-2022-49651

CVE-2022-49651 affects the Linux kernel. The advisory states that cleanup_srcu_struct() now checks for a grace period that is started but not yet started, addressing a potential use-after-free (UAF). It is resolved by a commit tightening GP checks in cleanup_srcu_struct(), with references to kern...

CVE-2022-49651 srcu: Tighten cleanup_srcu_struct() GP checks

In the Linux kernel, the following vulnerability has been resolved: srcu: Tighten cleanupsrcustruct GP checks Currently, cleanupsrcustruct checks for a grace period in progress, but it does not check for a grace period that has not yet started but which might start at any time. Such a situation...

CVE-2022-49636

CVE-2022-49636 affects the Linux kernel VLAN code, specifically a memory leak in vlan_newlink/vlan_changelink paths. The issue arises when a memory allocation fails in vlan_changelink() after prior allocations succeed; memory allocated for egress priority/vlan_dev structures may remain referenced...

CVE-2022-49568 KVM: Don't null dereference ops->destroy

In the Linux kernel, the following vulnerability has been resolved: KVM: Don't null dereference ops-destroy A KVM device cleanup happens in either of two callbacks: 1 destroy which is called when the VM is being destroyed; 2 release which is called when a device fd is closed. Most KVM devices use...

CVE-2022-49568

CVE-2022-49568 affects the Linux kernel KVM code path, where a NULL dereference can occur during cleanup if destroy() is assumed non-NULL but is not (notably for some Book3s KVM devices that use release() instead). The root cause is an assumption in kvm_ioctl_create_device() that destroy() is alw...
