CVE-2026-68213

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

Description A memory leak occurs in the rtl2832 sdr driver within the media subsystem. The vb2 framework provides buffers to the driver via buf queue() before calling start streaming(). If the rtl2832 sdr start streaming() function returns an error without returning these buffers through vb2 buffer done(), the queued buffers leak. This issue is triggered by multiple error paths, including direct early returns and several goto err paths related to tuner setup, ADC setup, and allocation failures.

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