| Subject: CVE-2024-26776: spi: hisi-sfc-v3xx: Return IRQ_NONE if no interrupts were detected |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| spi: hisi-sfc-v3xx: Return IRQ_NONE if no interrupts were detected |
| |
| Return IRQ_NONE from the interrupt handler when no interrupt was |
| detected. Because an empty interrupt will cause a null pointer error: |
| |
| Unable to handle kernel NULL pointer dereference at virtual |
| address 0000000000000008 |
| Call trace: |
| complete+0x54/0x100 |
| hisi_sfc_v3xx_isr+0x2c/0x40 [spi_hisi_sfc_v3xx] |
| __handle_irq_event_percpu+0x64/0x1e0 |
| handle_irq_event+0x7c/0x1cc |
| |
| The Linux kernel CVE team has assigned CVE-2024-26776 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: |
