| Subject: CVE-2024-42153: i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr |
| |
| When del_timer_sync() is called in an interrupt context it throws a warning |
| because of potential deadlock. The timer is used only to exit from |
| wait_for_completion() after a timeout so replacing the call with |
| wait_for_completion_timeout() allows to remove the problematic timer and |
| its related functions altogether. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42153 to this issue. |

| 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: |
