CVE-2026-93077: Linux

Описание

Оригинално описание

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.
