Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to memory management within the vidtv driver. Specifically, local pointers are not initialized to NULL after memory ownership is transferred during the processing of Program Association Table (PAT), Service Description Table (SDT), and Event Information Table (EIT) data. This can lead to a use-after-free and double-free condition when the
vidtv psi pmt create sec for each pat entry() function fails and memory is subsequently freed by vidtv psi * table destroy() and then accessed and freed again by vidtv psi * event destroy(). The vulnerable function is vidtv channel si init().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
