| Subject: CVE-2024-47723: jfs: fix out-of-bounds in dbNextAG() and diAlloc() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| jfs: fix out-of-bounds in dbNextAG() and diAlloc() |
| |
| In dbNextAG() , there is no check for the case where bmp->db_numag is |
| greater or same than MAXAG due to a polluted image, which causes an |
| out-of-bounds. Therefore, a bounds check should be added in dbMount(). |
| |
| And in dbNextAG(), a check for the case where agpref is greater than |
| bmp->db_numag should be added, so an out-of-bounds exception should be |
| prevented. |
| |
| Additionally, a check for the case where agno is greater or same than |
| MAXAG should be added in diAlloc() to prevent out-of-bounds. |
| |
| The Linux kernel CVE team has assigned CVE-2024-47723 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: |
