Linux Kernel up to 6.1.1 mmc_add_host return value

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability marked as critical has been reported in Linux Kernel up to 6.1.1. This impacts the function mmc_add_host. This manipulation causes return value. This vulnerability is registered as CVE-2022-50353. No exploit is available. It is suggested to upgrade the affected component.

Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.1.1. Affected by this vulnerability is the function mmc_add_host. The manipulation with an unknown input leads to a return value vulnerability. The CWE definition for the vulnerability is CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: mmc: wmt-sdmmc: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path. So fix this by checking the return value and goto error path which will call mmc_free_host(), besides, clk_disable_unprepare() also needs be called.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2022-50353 since 09/16/2025. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/23/2025).

The vulnerability scanner Nessus provides a plugin with the ID 265666 (Linux Distros Unpatched Vulnerability : CVE-2022-50353), which helps to determine the existence of the flaw in a target environment.
