CVE-2026-74275 cxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach()

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix out-of-bounds access in cxlcancelautoattach In cxlcancelautoattach, it assumes cxled-pos is a valid index for accessing p-targets. However, cxled-pos can be set to negative errno in cxlregionsorttargets if...

CVE-2026-74275

The CVE-2026-74275 entry is about the Linux kernel driver cxl/region where cxl_cancel_auto_attach() can access p->targets[] using a potentially negative index cxled->pos. The root cause is that cxled->pos may be set to a negative errno in cxl_region_sort_targets() if cxl_calc_interleave_...

CVE-2026-74273

CVE-2026-74273 affects the Linux kernel’s cxl/region logic. The fix expands the range lock and renames it to a new lock called regions_lock to disable region deletion during two critical windows: between construct_region() and attach_target(), and between device_add() and registering the remove a...
