Description OSIDB Bzimport 2025-12-30 13:11:35 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: dvb-usb: m920x: Fix a potential memory leak in m920x_i2c_xfer()

'read' is freed when it is known to be NULL, but not when a read error
occurs.

Revert the logic to avoid a small leak, should a m920x_read() call fail.
