| Subject: CVE-2024-41069: ASoC: topology: Fix references to freed memory |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: topology: Fix references to freed memory |
| |
| Most users after parsing a topology file, release memory used by it, so |
| having pointer references directly into topology file contents is wrong. |
| Use devm_kmemdup(), to allocate memory as needed. |
| |
| The Linux kernel CVE team has assigned CVE-2024-41069 to this issue. |
| |
| |
| Affected and fixed versions |
| =========================== |
| |
| Fixed in 6.1.101 with commit b188d7f3dfab10e332e3c1066e18857964a520d2 |

| 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: |
