| Subject: CVE-2024-26855: net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink() |
| |
| The function ice_bridge_setlink() may encounter a NULL pointer dereference |
| if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently |
| in nla_for_each_nested(). To address this issue, add a check to ensure that |
| br_spec is not NULL before proceeding with the nested attribute iteration. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26855 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: |
