     user address (bsc#1198133)
   - CVE-2022-1011: A use-after-free flaw was found in the FUSE filesystem in
     the way a user triggers write(). This flaw allowed a local user to gain
     unauthorized access to data from the FUSE filesystem, resulting in
     privilege escalation. (bsc#1197344)
   - - CVE-2021-39698: In aio_poll_complete_work of aio.c, there was a
     possible memory corruption due to a use after free. This could lead to
     local escalation of privilege with no additional execution privileges
     needed. User interaction is not needed for exploitation. (bsc#1196959)
