JSON

A use-after-free flaw was found in the Linux kernel’s dvb-core subsystem (DVB API used by Digital TV devices) in how a user physically removed a USB device (such as a DVB demultiplexer device) while running malicious code. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Mitigation

To mitigate this issue, prevent the module dvb-core from being loaded. Please see <https://access.redhat.com/solutions/41278> for information on how to blacklist a kernel module to prevent it from loading automatically.
