About this tag
CVE-2025-37911 is a Linux kernel vulnerability in the Broadcom NetXtreme-E (bnxt_en) network driver that was fixed in May 2025. The bug involves an out-of-bounds memcpy() operation triggered when administrators use the ethtool -w command to retrieve firmware coredumps. This memory corruption can be detected by KFENCE, a kernel memory error detector. The fix specifically addresses the memory safety issue in the bnxt_en driver, which is commonly used in data-center NICs. Users and administrators should apply the kernel patch to prevent potential system instability or exploitation.
