| Subject: CVE-2025-21957: scsi: qla1280: Fix kernel oops when debug level > 2 |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: qla1280: Fix kernel oops when debug level > 2 |
| |
| A null dereference or oops exception will eventually occur when qla1280.c |
| driver is compiled with DEBUG_QLA1280 enabled and ql_debug_level > 2. I |
| think its clear from the code that the intention here is sg_dma_len(s) not |
| length of sg_next(s) when printing the debug info. |
| |
| The Linux kernel CVE team has assigned CVE-2025-21957 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: |
