CVE ID : CVE-2021-47604
Published : June 19, 2024, 3:15 p.m. | 1 hour, 4 minutes ago
Description : In the Linux kernel, the following vulnerability has been resolved:
vduse: check that offset is within bounds in get_config()
This condition checks “len” but it does not check “offset” and that
could result in an out of bounds read if “offset > dev->config_size”.
The problem is that since both variables are unsigned the
“dev->config_size – offset” subtraction would result in a very high
unsigned value.
I think these checks might not be necessary because “len” and “offset”
are supposed to already have been validated using the
vhost_vdpa_config_validate() function. But I do not know the code
perfectly, and I like to be safe.
Severity: 0.0 | NA
