CVE-2019-15902

Priority
Description
A backporting error was discovered in the Linux stable/longterm kernel
4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141,
4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream
"x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()" commit
reintroduced the Spectre vulnerability that it aimed to eliminate. This
occurred because the backport process depends on cherry picking specific
commits, and because two (correctly ordered) code lines were swapped.
Ubuntu-Description
Brad Spengler discovered that a Spectre mitigation was improperly
implemented in the ptrace susbsystem of the Linux kernel. A local attacker
could possibly use this to expose sensitive information.
