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.

Security readout for executives and security teams

This is a Linux kernel crash bug limited to powerpc systems running affected kernels. A local user or process can crash the machine, causing service interruption. The supplied sources do not describe remote code execution or data theft. Exposure is likely limited to powerpc Linux systems running kernels before 4.3.5 or vendor kernels without the backported fix. Shared shell, build, hosting, or multi-user environments have higher practical risk. Address during normal patch operations, with faster action for shared powerpc infrastructure. Business impact is availability loss from local crashes, not confirmed remote compromise. Mitigation focus: Upgrade to Linux 4.3.5 or a vendor kernel containing the backported fix.; Review Red Hat advisories if using affected Red Hat Enterprise Linux packages.; Prioritize shared powerpc systems where untrusted local code can run..
