| Subject: CVE-2024-53156: wifi: ath9k: add range check for conn_rsp_epid in htc_connect_service() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: ath9k: add range check for conn_rsp_epid in htc_connect_service() |
| |
| I found the following bug in my fuzzer: |
| |
| UBSAN: array-index-out-of-bounds in drivers/net/wireless/ath/ath9k/htc_hst.c:26:51 |
| index 255 is out of range for type 'htc_endpoint [22]' |
| CPU: 0 UID: 0 PID: 8 Comm: kworker/0:0 Not tainted 6.11.0-rc6-dirty #14 |
| Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 |
| Workqueue: events request_firmware_work_func |
| Call Trace: |
| <TASK> |
| dump_stack_lvl+0x180/0x1b0 |
| __ubsan_handle_out_of_bounds+0xd4/0x130 |
| htc_issue_send.constprop.0+0x20c/0x230 |

| ath9k_wmi_cmd+0x41d/0x610 |
| ? mark_held_locks+0x9f/0xe0 |
| ... |
| |
| Since this bug has been confirmed to be caused by insufficient verification |
| of conn_rsp_epid, I think it would be appropriate to add a range check for |
| conn_rsp_epid to htc_connect_service() to prevent the bug from occurring. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53156 to this issue. |

| ========== |
| |
| 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: |
