CVE-2023-53287

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: cdns3: Put the cdns set active part outside the spin lock<br /> <br /> The device may be scheduled during the resume process,<br /> so this cannot appear in atomic operations. Since<br /> pm_runtime_set_active will resume suppliers, put set<br /> active outside the spin lock, which is only used to<br /> protect the struct cdns data structure, otherwise the<br /> kernel will report the following warning:<br /> <br /> BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:1163<br /> in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 651, name: sh<br /> preempt_count: 1, expected: 0<br /> RCU nest depth: 0, expected: 0<br /> CPU: 0 PID: 651 Comm: sh Tainted: G WC 6.1.20 #1<br /> Hardware name: Freescale i.MX8QM MEK (DT)<br /> Call trace:<br /> dump_backtrace.part.0+0xe0/0xf0<br /> show_stack+0x18/0x30<br /> dump_stack_lvl+0x64/0x80<br /> dump_stack+0x1c/0x38<br /> __might_resched+0x1fc/0x240<br /> __might_sleep+0x68/0xc0<br /> __pm_runtime_resume+0x9c/0xe0<br /> rpm_get_suppliers+0x68/0x1b0<br /> __pm_runtime_set_status+0x298/0x560<br /> cdns_resume+0xb0/0x1c0<br /> cdns3_controller_resume.isra.0+0x1e0/0x250<br /> cdns3_plat_resume+0x28/0x40
