CVE-2022-50268

A flaw was found in the Linux kernel component mmc: moxart. A local attacker with low privileges could exploit this vulnerability by triggering an improper return value check in the mmc_add_host() function. This oversight can lead to a memory leak, which may ultimately cause a kernel crash, resulting in a Denial of Service (DoS) for the system.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the moxart kernel module from loading. Create a file /etc/modprobe.d/blacklist-moxart.conf with the content blacklist moxart. A system reboot is required for this change to take effect. This may impact systems that rely on the Moxart MMC controller.
