| Subject: CVE-2024-41016: ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry() |
| |
| xattr in ocfs2 maybe 'non-indexed', which saved with additional space |
| requested. It's better to check if the memory is out of bound before |
| memcmp, although this possibility mainly comes from crafted poisonous |
| images. |
| |
| The Linux kernel CVE team has assigned CVE-2024-41016 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: |
