| Subject: CVE-2024-53053: scsi: ufs: core: Fix another deadlock during RTC update |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: ufs: core: Fix another deadlock during RTC update |
| |
| If ufshcd_rtc_work calls ufshcd_rpm_put_sync() and the pm's usage_count |
| is 0, we will enter the runtime suspend callback. However, the runtime |
| suspend callback will wait to flush ufshcd_rtc_work, causing a deadlock. |
| |
| Replace ufshcd_rpm_put_sync() with ufshcd_rpm_put() to avoid the |
| deadlock. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53053 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: |
