CVE-2024-43851
描述
In the Linux kernel, the following vulnerability has been resolved: soc: xilinx: rename cpu_number1 to dummy_cpu_number The per cpu variable cpu_number1 is passed to xlnx_event_handler as argument "dev_id", but it is not used in this function. So drop the initialization of this variable and rename it to dummy_cpu_number. This patch is to fix the following call trace when the kernel option CONFIG_DEBUG_ATOMIC_SLEEP is enabled: BUG: sleeping function called from invalid context at include/linux/sched/mm.h:274 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1, name: swapper/0 preempt_count: 1, expected: 0 CPU: 0 PID: 1 Comm: swapper/0 Not tainted 6.1.0 #53 Hardware name: Xilinx Versal vmk180 Eval board rev1.1 (QSPI) (DT) Call trace: dump_backtrace+0xd0/0xe0 show_stack+0x18/0x40 dump_stack_lvl+0x7c/0xa0 dump_stack+0x18/0x34 __might_resched+0x10c/0x140 __might_sleep+0x4c/0xa0 __kmem_cache_alloc_node+0xf4/0x168 kmalloc_trace+0x28/0x38 __request_percpu_irq+0x74/0x138 xlnx_event_manager_probe+0xf8/0x298 platform_probe+0x68/0xd8
