Description In the Linux kernel, the following vulnerability has been resolved: xen/netfront: react properly to failing gnttab_end_foreign_access_ref() When calling gnttab_end_foreign_access_ref() the returned value must be tested and the reaction to that value should be appropriate. In case of failure in xennet_get_responses() the reaction should not be to crash the system, but to disable the network device. The calls in setup_netfront() can be replaced by calls of gnttab_end_foreign_access(). While at it avoid double free of ring pages and grant references via xennet_disconnect_backend() in this case. This is CVE-2022-23042 / part of XSA-396. --- V2: - avoid double free V3: - remove pointless initializer (Jan Beulich) This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
