| Subject: CVE-2025-38575: ksmbd: use aead_request_free to match aead_request_alloc |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ksmbd: use aead_request_free to match aead_request_alloc |
| |
| Use aead_request_free() instead of kfree() to properly free memory |
| allocated by aead_request_alloc(). This ensures sensitive crypto data |
| is zeroed before being freed. |
| |
| The Linux kernel CVE team has assigned CVE-2025-38575 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: |
