* kernel: stack overflow in do_proc_dointvec and proc_skip_spaces
(CVE-2022-4378)
* kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings
leads to stale TLB entry (CVE-2022-39188)
* kernel: use-after-free related to leaf anon_vma double reuse
(CVE-2022-42703)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
Bug Fix(es):
