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.
AI Analysis
Technical Summary
The Linux kernel contained a vulnerability in the cxl_cancel_auto_attach() function where cxled->pos was assumed to be a valid index for the p->targets[] array. However, cxled->pos could be set to a negative error code if cxl_calc_interleave_pos() failed, causing an out-of-bounds array access. This was resolved by modifying the code to walk through p->targets[] safely instead of using the potentially negative index directly.
Potential Impact
The vulnerability could lead to out-of-bounds memory access within the kernel, which may cause system instability or potentially allow an attacker to influence kernel memory. No specific exploitation details or active exploits are reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
