CVE-2026-93260 is a use-after-free vulnerability in the Linux kernel's powerpc/xive subsystem. The flaw occurs when the initialization of inter-processor interrupts (IPIs) fails, causing the system to free a global array but then continue to use it, leading to memory corruption. This issue has been addressed by propagating error returns to abort setup cleanly and prevent dereferencing freed memory.
