| Subject: CVE-2023-52799: jfs: fix array-index-out-of-bounds in dbFindLeaf |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| jfs: fix array-index-out-of-bounds in dbFindLeaf |
| |
| Currently while searching for dmtree_t for sufficient free blocks there |
| is an array out of bounds while getting element in tp->dm_stree. To add |
| the required check for out of bound we first need to determine the type |
| of dmtree. Thus added an extra parameter to dbFindLeaf so that the type |
| of tree can be determined and the required check can be applied. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52799 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: |
