Descriptions

In the Linux kernel, the following vulnerability has been resolved: gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully When running gpio test on nxp-ls1028 platform with below command
gpiomon --num-events=3 --rising-edge gpiochip1 25
There will be a warning trace as below:
Call trace:
free_irq+0x204/0x360
lineevent_free+0x64/0x70
gpio_ioctl+0x598/0x6a0
__arm64_sys_ioctl+0xb4/0x100
invoke_syscall+0x5c/0x130
......
el0t_64_sync+0x1a0/0x1a4
The reason of this issue is that calling request_threaded_irq()
function failed, and then lineevent_free() is invoked to release
the resource. Since the lineevent_state::irq was already set, so
the subsequent invocation of free_irq() would trigger the above
warning call trace. To fix this issue, set the lineevent_state::irq
after the IRQ register successfully.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gpiolib: cdev: configure lineevent_state::irq después del registro IRQ con éxito Al ejecutar la prueba gpio en la plataforma nxp-ls1028 con el siguiente comando gpiomon --num-events=3 --rising-edge gpiochip1 25 Habrá un seguimiento de advertencia como se muestra a continuación: Seguimiento de llamada: free_irq+0x204/0x360 lineevent_free+0x64/0x70 gpio_ioctl+0x598/0x6a0 __arm64_sys_ioctl+0xb4/0x100 invoke_syscall+0x5c/0x130 ...... 0x1a0/0x1a4 El motivo de este problema es que falló la llamada a la función request_threaded_irq() y luego se invoca lineevent_free() para liberar el recurso. Dado que lineevent_state::irq ya estaba configurado, la invocación posterior de free_irq() activaría el seguimiento de llamada de advertencia anterior. Para solucionar este problema, configure lineevent_state::irq después del registro IRQ correctamente.

The SUSE Linux Enterprise 15 SP5 Real Time kernel was updated to receive various security bug fixes.
