| Subject: CVE-2024-36481: tracing/probes: fix error check in parse_btf_field() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| tracing/probes: fix error check in parse_btf_field() |
| |
| btf_find_struct_member() might return NULL or an error via the |
| ERR_PTR() macro. However, its caller in parse_btf_field() only checks |
| for the NULL condition. Fix this by using IS_ERR() and returning the |
| error up the stack. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36481 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: |
| https://git.kernel.org/stable/c/ad4b202da2c498fefb69e5d87f67b946e7fe1e6a |
