NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
