| Subject: CVE-2024-42292: kobject_uevent: Fix OOB access within zap_modalias_env() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| kobject_uevent: Fix OOB access within zap_modalias_env() |
| |
| zap_modalias_env() wrongly calculates size of memory block to move, so |
| will cause OOB memory access issue if variable MODALIAS is not the last |
| one within its @env parameter, fixed by correcting size to memmove. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42292 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: |
