| Subject: CVE-2024-53101: fs: Fix uninitialized value issue in from_kuid and from_kgid |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| fs: Fix uninitialized value issue in from_kuid and from_kgid |
| |
| ocfs2_setattr() uses attr->ia_mode, attr->ia_uid and attr->ia_gid in |
| a trace point even though ATTR_MODE, ATTR_UID and ATTR_GID aren't set. |
| |
| Initialize all fields of newattrs to avoid uninitialized variables, by |
| checking if ATTR_MODE, ATTR_UID, ATTR_GID are initialized, otherwise 0. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53101 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: |
