CVE-2026-43344

CVE-2026-43344 affects the Linux kernel perf/x86/intel/uncore subsystem. The root cause is incorrect die ID initialization/lookup in snbep_pci2phy_map_init() that can produce die_id == -1 when CPUs are offline or when NUMA is disabled, causing uncore_device_to_die() to misbehave and PMON units to...
