| Subject: CVE-2024-47756: PCI: keystone: Fix if-statement expression in ks_pcie_quirk() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| PCI: keystone: Fix if-statement expression in ks_pcie_quirk() |
| |
| This code accidentally uses && where || was intended. It potentially |
| results in a NULL dereference. |
| |
| Thus, fix the if-statement expression to use the correct condition. |
| |

| 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: |
