| Subject: CVE-2024-56569: ftrace: Fix regression with module command in stack_trace_filter |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ftrace: Fix regression with module command in stack_trace_filter |
| |
| When executing the following command: |
| |
| # echo "write*:mod:ext3" > /sys/kernel/tracing/stack_trace_filter |
| |
| The current mod command causes a null pointer dereference. While commit |
| 0f17976568b3f ("ftrace: Fix regression with module command in stack_trace_filter") |
| has addressed part of the issue, it left a corner case unhandled, which still |
| results in a kernel crash. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56569 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: |
