CVE-2022-49669 mptcp: fix race on unaccepted mptcp sockets

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix race on unaccepted mptcp sockets When the listener socket owning the relevant request is closed, it frees the unaccepted subflows and that causes later deletion of the paired MPTCP sockets. The mptcp socket's worker ca...

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-2022-49568 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...
