Overview
CVE-2026-93077 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
cxl/features: Clamp Get Feature output size to the remaining buffer
cxl_get_feature() reads a feature in a loop but passes a fixed size_out
as the output capacity every iteration. On the last partial iteration
the buffer has less room left, so a device that returns more than asked
can overflow feat_out.
Use the per-iter size data_to_rd_size, which already tracks the
remaining room, as the output capacity.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
