A race condition was found in the Linux kernel’s media/dvb-core in
dvbdmx_write() function. This can result in a null pointer dereference
issue, possibly leading to a kernel panic or denial of service issue.

Notes

Author Note
Priority reason: The supposed race condition is hard to replicate and even so, there’s an existing lock in one of the caller functions. Lowering priority.
