Description OSIDB Bzimport 2024-07-30 09:09:09 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: dvb-frontends: tda10048: Fix integer overflow

state->xtal_hz can be up to 16M, so it can overflow a 32 bit integer
when multiplied by pll_mfactor.

Create a new 64 bit variable to hold the calculations.
