Description
In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Add buffer overflow check in MS get_info_ioctl
Add validation that the info size returned from the metric stream info
query is not exceeded when checked against the allocated buffer size.
If the firmware returns a size larger than the buffer, reject the
operation with -EOVERFLOW instead of proceeding with an incorrect
buffer copy.
Affected configurations
• linux linux kernel (>= 6.11 < 6.12.94)
• linux linux kernel (>= 6.13 < 6.18.36)
• linux linux kernel (>= 6.19 < 7.0.13)
• linux linux kernel 7.1
