Descriptions

In the Linux kernel, the following vulnerability has been resolved:

power: supply: bq27xxx-i2c: Do not free non existing IRQ

The bq27xxx i2c-client may not have an IRQ, in which case
client->irq will be 0. bq27xxx_battery_i2c_probe() already has
an if (client->irq) check wrapping the request_threaded_irq().

But bq27xxx_battery_i2c_remove() unconditionally calls
free_irq(client->irq) leading to:

[ 190.310742] ------------[ cut here ]------------
[ 190.310843] Trying to free already-free IRQ 0
[ 190.310861] WARNING: CPU: 2 PID: 1304 at kernel/irq/manage.c:1893 free_irq+0x1b8/0x310

Followed by a backtrace when unbinding the driver. Add
an if (client->irq) to bq27xxx_battery_i2c_remove() mirroring
probe() to fix this.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: alimentación: suministro: bq27xxx-i2c: no liberar IRQ no existente Es posible que el cliente bq27xxx i2c no tenga una IRQ, en cuyo caso client->irq será 0. bq27xxx_battery_i2c_probe( ) ya tiene una verificación if (cliente->irq) que envuelve request_threaded_irq(). Pero bq27xxx_battery_i2c_remove() llama incondicionalmente a free_irq(cliente->irq) lo que lleva a: [190.310742] ------------[ cortar aquí ]------------ [ 190.310843] Intentando liberar IRQ 0 [190.310861] que ya está libre ADVERTENCIA: CPU: 2 PID: 1304 en kernel/irq/manage.c:1893 free_irq+0x1b8/0x310 Seguido de un seguimiento al desvincular el controlador. Agregue un if (cliente->irq) a bq27xxx_battery_i2c_remove() mirroring probe() para solucionar este problema.
