CVE-2022-50640

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel's mmc core component related to handling non-standard SDIO cards. Specifically, the issue arises from an incorrect reference counter management when a non-standard SDIO card is removed. The SDIO tuple is allocated only for standard SDIO cards, leading to memory corruption and potentially a kernel panic when a non-standard card is removed because the card device's reference counter is not properly incremented during initialization but is decremented during release.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
