| Subject: CVE-2024-53173: NFSv4.0: Fix a use-after-free problem in the asynchronous open() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| NFSv4.0: Fix a use-after-free problem in the asynchronous open() |
| |
| Yang Erkun reports that when two threads are opening files at the same |
| time, and are forced to abort before a reply is seen, then the call to |
| nfs_release_seqid() in nfs4_opendata_free() can result in a |
| use-after-free of the pointer to the defunct rpc task of the other |
| thread. |
| The fix is to ensure that if the RPC call is aborted before the call to |
| nfs_wait_on_sequence() is complete, then we must call nfs_release_seqid() |
| in nfs4_open_release() before the rpc_task is freed. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53173 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: |
