    CVE-2022-39188

    Summary: kernel security update

    Details: The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.(CVE-2022-39188)
