| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ACPI: LPIT: Avoid u32 multiplication overflow |
| |
| In lpit_update_residency() there is a possibility of overflow |
| in multiplication, if tsc_khz is large enough (> UINT_MAX/1000). |
| |
| Change multiplication to mul_u32_u32(). |
| |
| Found by Linux Verification Center (linuxtesting.org) with SVACE. |

| 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: |
