| Subject: CVE-2024-50057: usb: typec: tipd: Free IRQ only if it was requested before |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: typec: tipd: Free IRQ only if it was requested before |
| |
| In polling mode, if no IRQ was requested there is no need to free it. |
| Call devm_free_irq() only if client->irq is set. This fixes the warning |
| caused by the tps6598x module removal: |
| |
| WARNING: CPU: 2 PID: 333 at kernel/irq/devres.c:144 devm_free_irq+0x80/0x8c |
| ... |

| Mitigation |
| ========== |
| |
| 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: |
| https://git.kernel.org/stable/c/b72bf5cade51ba4055c8a8998d275e72e6b521ce |
