With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.

The Linux Kernel, the operating system core itself. Security Fix(es): There are use-after-free vulnerabilities in net/ax25/af_ax25.c of linux that allow attacker to crash linux kernel by simulating ax25 device from user space.(CVE-2022-1204) The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag.(CVE-2022-30594)
