| Subject: CVE-2024-57804: scsi: mpi3mr: Fix corrupt config pages PHY state is switched in sysfs |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: mpi3mr: Fix corrupt config pages PHY state is switched in sysfs |
| |
| The driver, through the SAS transport, exposes a sysfs interface to |
| enable/disable PHYs in a controller/expander setup. When multiple PHYs |
| are disabled and enabled in rapid succession, the persistent and current |
| config pages related to SAS IO unit/SAS Expander pages could get |
| corrupted. |
| |
| Use separate memory for each config request. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57804 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: |
| https://git.kernel.org/stable/c/869fdc6f0606060301aef648231e186c7c542f5a |
