| Subject: CVE-2024-46673: scsi: aacraid: Fix double-free on probe failure |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: aacraid: Fix double-free on probe failure |
| |
| aac_probe_one() calls hardware-specific init functions through the |
| aac_driver_ident::init pointer, all of which eventually call down to |
| aac_init_adapter(). |
| |
| If aac_init_adapter() fails after allocating memory for aac_dev::queues, |
| it frees the memory but does not clear that member. |
| |
| After the hardware-specific init function returns an error, |
| aac_probe_one() goes down an error path that frees the memory pointed to |
| by aac_dev::queues, resulting.in a double-free. |
| |
| The Linux kernel CVE team has assigned CVE-2024-46673 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: |
