CVE-2015-8844: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

The signal implementation in the Linux kernel before 4.3.5 on powerpc platforms does not check for an MSR with both the S and T bits set, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application.

Affected products

• Linux Linux Kernel: up to and including 4.3.4
