| Subject: CVE-2024-27078: media: v4l2-tpg: fix some memleaks in tpg_alloc |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: v4l2-tpg: fix some memleaks in tpg_alloc |
| |
| In tpg_alloc, resources should be deallocated in each and every |
| error-handling paths, since they are allocated in for statements. |
| Otherwise there would be memleaks because tpg_free is called only when |
| tpg_alloc return 0. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27078 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: |
