CVE-2024-49963

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mailbox: bcm2835: Fix timeout during suspend mode<br /> <br /> During noirq suspend phase the Raspberry Pi power driver suffer of<br /> firmware property timeouts. The reason is that the IRQ of the underlying<br /> BCM2835 mailbox is disabled and rpi_firmware_property_list() will always<br /> run into a timeout [1].<br /> <br /> Since the VideoCore side isn&amp;#39;t consider as a wakeup source, set the<br /> IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled<br /> during suspend-resume cycle.<br /> <br /> [1]<br /> PM: late suspend of devices complete after 1.754 msecs<br /> WARNING: CPU: 0 PID: 438 at drivers/firmware/raspberrypi.c:128<br /> rpi_firmware_property_list+0x204/0x22c<br /> Firmware transaction 0x00028001 timeout<br /> Modules linked in:<br /> CPU: 0 PID: 438 Comm: bash Tainted: G C 6.9.3-dirty #17<br /> Hardware name: BCM2835<br /> Call trace:<br /> unwind_backtrace from show_stack+0x18/0x1c<br /> show_stack from dump_stack_lvl+0x34/0x44<br /> dump_stack_lvl from __warn+0x88/0xec<br /> __warn from warn_slowpath_fmt+0x7c/0xb0<br /> warn_slowpath_fmt from rpi_firmware_property_list+0x204/0x22c<br /> rpi_firmware_property_list from rpi_firmware_property+0x68/0x8c<br /> rpi_firmware_property from rpi_firmware_set_power+0x54/0xc0<br /> rpi_firmware_set_power from _genpd_power_off+0xe4/0x148<br /> _genpd_power_off from genpd_sync_power_off+0x7c/0x11c<br /> genpd_sync_power_off from genpd_finish_suspend+0xcc/0xe0<br /> genpd_finish_suspend from dpm_run_callback+0x78/0xd0<br /> dpm_run_callback from device_suspend_noirq+0xc0/0x238<br /> device_suspend_noirq from dpm_suspend_noirq+0xb0/0x168<br /> dpm_suspend_noirq from suspend_devices_and_enter+0x1b8/0x5ac<br /> suspend_devices_and_enter from pm_suspend+0x254/0x2e4<br /> pm_suspend from state_store+0xa8/0xd4<br /> state_store from kernfs_fop_write_iter+0x154/0x1a0<br /> kernfs_fop_write_iter from vfs_write+0x12c/0x184<br /> vfs_write from ksys_write+0x78/0xc0<br /> ksys_write from ret_fast_syscall+0x0/0x54<br /> Exception stack(0xcc93dfa8 to 0xcc93dff0)<br /> [...]<br /> PM: noirq suspend of devices complete after 3095.584 msecs
