CVE-2025-37866: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: mlxbf-bootctl: use sysfs_emit_at() in secure_boot_fuse_state_show() A warning is seen when running the latest kernel on a BlueField SOC: [251.512704] ------------[ cut here ]------------ [251.512711] invalid sysfs_emit: buf:0000000003aa32ae [251.512720] WARNING: CPU: 1 PID: 705264 at fs/sysfs/file.c:767 sysfs_emit+0xac/0xc8 The warning is triggered because the mlxbf-bootctl driver invokes "sysfs_emit()" with a buffer pointer that is not aligned to the start of the page. The driver should instead use "sysfs_emit_at()" to support non-zero offsets into the destination buffer.

Affected products

• Linux Linux Kernel: from 6.14, before 6.14.4 (fixed in 6.14.4); version 6.15 only
