Description

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