| Subject: CVE-2024-56766: mtd: rawnand: fix double free in atmel_pmecc_create_user() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mtd: rawnand: fix double free in atmel_pmecc_create_user() |
| |
| The "user" pointer was converted from being allocated with kzalloc() to |
| being allocated by devm_kzalloc(). Calling kfree(user) will lead to a |
| double free. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56766 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: |
