In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution
may occur because of a race condition, as demonstrated by code in
enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect
against a concurrent page table upgrade, aka CID-3f777e19d171. A crash
could also occur.
