| Subject: CVE-2024-47697: drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error |
| |
| Ensure index in rtl2830_pid_filter does not exceed 31 to prevent |
| out-of-bounds access. |
| |
| dev->filters is a 32-bit value, so set_bit and clear_bit functions should |
| only operate on indices from 0 to 31. If index is 32, it will attempt to |
| access a non-existent 33rd bit, leading to out-of-bounds access. |
| Change the boundary check from index > 32 to index >= 32 to resolve this |
| issue. |
| |
| The Linux kernel CVE team has assigned CVE-2024-47697 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: |
