AI-suggested
A fix has been implemented in the Linux kernel by adding validation for the full buffer range in ivpu_to_cpu_addr(). Users should apply the updated kernel versions that include this patch to mitigate the vulnerability.
Description
A vulnerability in the Linux kernel's accel/ivpu component was resolved by adding a size parameter to the ivpu_to_cpu_addr() function and validating that the entire buffer range remains within bounds. This fix prevents potential out-of-bounds access by ensuring the full buffer range [vpu_addr, vpu_addr + size) is validated.
