A race condition flaw leading to a use-after-free issue was found in the Linux kernel media subsystem in the DVB core device driver. It could occur in the dvb_register_device() function due to the file_operations structure (fops) being dynamically allocated and later kfreed. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.
Mitigation
To mitigate this issue, it is possible to prevent the affected code from being loaded by blacklisting the dvb-core kernel module. For instructions on how to blacklist a kernel module, please see <https://access.redhat.com/solutions/41278>.
