CVE-2026-72026

The CVE-2026-72026 vulnerability is in the Linux kernel IRQ subsystem for riscv IMSIC early initialization. The issue: imsic_early_acpi_init() allocates a firmware node before IMSIC state setup; if imsic_setup_state() fails, the allocated fwnode is not freed. The fix adds cleanup on the error pat...
