In the Linux kernel, the following vulnerability has been resolved: nvme: fix FDP fdpcidx bounds check The fdpcidx bounds check sets n = NUMFDPC + 1… (CVE-2026-74361)
A vulnerability in the Linux kernel's NVMe driver involved an incorrect bounds check on the fdpcidx value. The check used a greater-than operator instead of greater-than-or-equal, allowing an out-of-bounds index equal to NUMFDPC + 1. This flaw has been resolved in the Linux kernel.
AI Analysis
Technical Summary
The Linux kernel NVMe driver contained a vulnerability in the fdpcidx bounds check logic. Specifically, the code set n = NUMFDPC + 1 but used a > operator instead of >=, which incorrectly allowed the fdpcidx value to equal n, resulting in an out-of-bounds condition. This vulnerability has been fixed by correcting the bounds check to properly reject fdpcidx values equal to n.
Potential Impact
The vulnerability could allow improper handling of an out-of-bounds index in the NVMe driver, potentially leading to memory safety issues. However, no specific impact details or exploitation scenarios are provided in the available data.
Mitigation Recommendations
A fix has been applied in the Linux kernel to correct the bounds check in the NVMe driver. Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed in the data; check the Linux kernel vendor advisory for the exact fixed version and remediation guidance.
