| Subject: CVE-2024-27412: power: supply: bq27xxx-i2c: Do not free non existing IRQ |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27412 to this issue. |

| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
