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.

Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2022-49267)

Note that Nessus relies on the presence of the package as reported by the vendor.
