"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: fbtft: make dirty_lock IRQ-safe\n\nfbtft_mkdirty() can be reached from the fbcon rendering path while\nprocessing printk() in hardirq context. Meanwhile, dirty_lock is also\ntaken by fbtft_deferred_io() in workqueue context with local interrupts\nenabled.\n\nLockdep reports a possible IRQ lock inversion involving dirty_lock and\nconsole_owner. A hardirq can interrupt a CPU holding dirty_lock and\nenter the console rendering path, which can attempt to acquire\ndirty_lock again.\n\nThe following lockdep report was observed on an RK3566 system with\nCONFIG_PROVE_LOCKING enabled:\n\n WARNING: possible irq lock inversion dependency detected\n swapper/2/0 just changed the state of lock:\n (console_owner){-...}-{0:0}\n but this lock took another, HARDIRQ-unsafe lock in the past:\n (&par->dirty_lock){+.+.}-{2:2}\n\n CPU0 CPU1\n ---- ----\n lock(&par->dirty_lock);\n local_irq_disable();\n lock(console_owner);\n lock(&par->dirty_lock);\n <Interrupt>\n lock(console_owner);\n\n *** DEADLOCK ***\n\nUse spin_lock_irqsave() for fbtft_mkdirty() and spin_lock_irq() for\nfbtft_deferred_io(). They only access the dirty line range, so the\nIRQ-off regions remain short."
