AI-suggested
A patch is available that fixes this vulnerability by adding overflow checks in the control_update size calculation. Users should apply the official Linux kernel updates that include this fix. No additional mitigation steps are indicated by the vendor advisory.
Description
A vulnerability in the Linux kernel's ASoC SOF ipc3-control component was fixed. The flaw involved arithmetic overflow in the control_update size calculation on 32-bit platforms, potentially allowing out-of-bounds memory access. This could lead to system compromise. The issue is addressed by adding overflow checks in the size calculation logic.
