CVE-2022-50132:
Linux Kernel vulnerability analysis and mitigation
Overview
A vulnerability was discovered in the Linux kernel's USB CDNS3 driver, identified as CVE-2022-50132. The issue involves incorrect placement of 'privep' assignment in cdns3gadgetepdequeue() and cdns3gadgetep_enable() functions. This vulnerability was discovered by the Linux Verification Center (linuxtesting.org) using their SVACE tool (NVD).
Technical details
The vulnerability stems from a NULL pointer dereference issue in the USB CDNS3 driver implementation. The problem occurs specifically in two functions: cdns3gadgetepdequeue() and cdns3gadgetepenable(). When the 'ep' parameter is NULL, the eptocdns3ep(ep) function returns an invalid pointer. The subsequent attempt to dereference this pointer through privep->cdns3_dev leads to a kernel panic (Wiz).
Impact
When exploited, this vulnerability can cause a kernel panic, leading to system instability and potential denial of service. The impact is primarily on system availability, as the NULL pointer dereference results in an immediate kernel crash (Wiz).
