Description OSIDB Bzimport 2025-02-26 03:04:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mmc: core: use sysfs_emit() instead of sprintf()

sprintf() (still used in the MMC core for the sysfs output) is vulnerable
to the buffer overflow.  Use the new-fangled sysfs_emit() instead.

Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
