| Subject: CVE-2025-21735: NFC: nci: Add bounds checking in nci_hci_create_pipe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| NFC: nci: Add bounds checking in nci_hci_create_pipe() |
| |
| The "pipe" variable is a u8 which comes from the network. If it's more |
| than 127, then it results in memory corruption in the caller, |
| nci_hci_connect_gate(). |
| |
| The Linux kernel CVE team has assigned CVE-2025-21735 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: |
