CVE-2026-93259

The Linux kernel contains a vulnerability in powerpc/irq when CONFIG_PPC_KERNEL_PCREL is enabled. The functions call_do_irq() and call_do_softirq() use inline assembly for stack switching but fail to include r2 in their clobber lists. Because r2 is no longer reserved for the TOC pointer in this m...
