CVE-2024-43851

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