Description Dhananjay Arunesh 2019-11-21 12:27:06 UTC 
In kernel/compat.c in the Linux kernel, as used in Google Chrome OS and other products, there is a possible out-of-bounds read. restart_syscall uses uninitialized data when restarting compat_sys_nanosleep. NOTE: this is disputed because the code path is unreachable.

This was fixed upstream in 3.17,  and has never been an issue in any currently supported fedora release.
