CVE-2026-74275 in Linux
요약
\~에 의해 MITRE • 2026. 08. 15.
In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach()
In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for accessing p->targets[]. However, cxled->pos can be set to negative errno
in cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This causes the driver to use a negative index to access p->targets[],
resulting in out-of-bounds access.
Fix it by walking p->targets[] instead of using cxled->pos directly.
