Integer overflow in the perf_event_interrupt function in arch/powerpc/kernel/perf_event.c in the Linux kernel before 2.6.39 on powerpc platforms allows local users to cause a denial of service (unhandled performance monitor exception) via vectors that trigger certain outcomes of performance events.

Security readout for executives and security teams

This is an old Linux kernel issue affecting PowerPC systems. A local user could trigger a kernel performance-event handling bug and crash the system, causing denial of service. The sources do not show remote attack, privilege escalation, or active exploitation. Exposure is most likely on legacy PowerPC Linux hosts running kernels before 2.6.39 or vendor kernels without the referenced fix. Systems without untrusted local users are lower risk. Treat as a targeted legacy-platform availability risk. It should be remediated in routine vulnerability maintenance unless affected PowerPC systems support critical operations or allow many local users. Mitigation focus: Upgrade affected PowerPC kernels to 2.6.39 or a vendor-supported fixed kernel.; Confirm vendor kernel advisories for backported fixes before relying on version numbers alone.; Reduce or remove untrusted local shell access on legacy PowerPC hosts..
