| Subject: CVE-2024-50131: tracing: Consider the NULL character when validating the event length |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| tracing: Consider the NULL character when validating the event length |
| |
| strlen() returns a string length excluding the null byte. If the string |
| length equals to the maximum buffer length, the buffer will have no |
| space for the NULL terminating character. |
| |
| This commit checks this condition and returns failure for it. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50131 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: |
