5.5 · Medium

Score breakdown

A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl() function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.

From the Ubuntu Security Team

It was discovered that the Linux kernel could incorrectly enable Indirect Branch Speculation after it has been disabled for a process via a prctl() call. A local attacker could possibly use this to expose sensitive information.
