| Subject: CVE-2024-50149: drm/xe: Don't free job in TDR |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/xe: Don't free job in TDR |
| |
| Freeing job in TDR is not safe as TDR can pass the run_job thread |
| resulting in UAF. It is only safe for free job to naturally be called by |
| the scheduler. Rather free job in TDR, add to pending list. |
| |
| (cherry picked from commit ea2f6a77d0c40d97f4a4dc93fee4afe15d94926d) |

| 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/be8fe75e57f8fa3f87e3b1c283cc7cd9f9b80867 |
