CVE-2026-93077 in Linux
Tóm tắt
Bởi MITRE • 17/09/2026
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.
