| Subject: CVE-2023-52838: fbdev: imsttfb: fix a resource leak in probe |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| fbdev: imsttfb: fix a resource leak in probe |
| |
| I've re-written the error handling but the bug is that if init_imstt() |
| fails we need to call iounmap(par->cmap_regs). |
| |
| The Linux kernel CVE team has assigned CVE-2023-52838 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: |
