| Subject: CVE-2022-49503: ath9k_htc: fix potential out of bounds access with invalid rxstatus->rs_keyix |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ath9k_htc: fix potential out of bounds access with invalid rxstatus->rs_keyix |
| |
| The "rxstatus->rs_keyix" eventually gets passed to test_bit() so we need to |
| ensure that it is within the bitmap. |
| |
| drivers/net/wireless/ath/ath9k/common.c:46 ath9k_cmn_rx_accept() |
| error: passing untrusted data 'rx_stats->rs_keyix' to 'test_bit()' |
| |
| The Linux kernel CVE team has assigned CVE-2022-49503 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: |
