| Subject: CVE-2024-36010: igb: Fix string truncation warnings in igb_set_fw_version |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| igb: Fix string truncation warnings in igb_set_fw_version |
| |
| Commit 1978d3ead82c ("intel: fix string truncation warnings") |
| fixes '-Wformat-truncation=' warnings in igb_main.c by using kasprintf. |
| |
| drivers/net/ethernet/intel/igb/igb_main.c:3092:53: warning：‘%d’ directive output may be truncated writing between 1 and 5 bytes into a region of size between 1 and 13 [-Wformat-truncation=] |
| 3092 | "%d.%d, 0x%08x, %d.%d.%d", |
| | ^~ |
| drivers/net/ethernet/intel/igb/igb_main.c:3092:34: note：directive argument in the range [0, 65535] |
| 3092 | "%d.%d, 0x%08x, %d.%d.%d", |
| | ^~~~~~~~~~~~~~~~~~~~~~~~~ |
| drivers/net/ethernet/intel/igb/igb_main.c:3092:34: note：directive argument in the range [0, 65535] |
| drivers/net/ethernet/intel/igb/igb_main.c:3090:25: note：‘snprintf’ output between 23 and 43 bytes into a destination of size 32 |
| |
| kasprintf() returns a pointer to dynamically allocated memory |
| which can be NULL upon failure. |
| |
| Fix this warning by using a larger space for adapter->fw_version, |
| and then fall back and continue to use snprintf. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36010 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: |
