A high-severity vulnerability (CVE-2025-71078) in the Linux kernel's PowerPC hash MMU implementation could cause stale Segment Lookaside Buffer (SLB) entries to persist across CPUs, leading to SLB multi-hit errors. This occurs due to inconsistencies between hardware SLB and software preload cache during optimized context switches. The issue affects certain Linux kernel versions prior to specific patched releases and has been resolved in updated kernel versions.
