CVE-2024-42223: media: dvb-frontends: tda10048: Fix integer overflow

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.

Security readout for executives and security teams

Plain-English summary

This CVE is a Linux kernel bug in a DVB media frontend driver. A calculation can overflow a 32-bit integer, so the kernel fix uses 64-bit arithmetic. The public sources do not show active exploitation, CVSS, or a clear business-impact scenario.

Executive priority

Treat this as a targeted kernel maintenance issue, not an emergency from the current evidence. Patch through normal kernel update processes, with faster handling for systems using DVB media hardware or custom kernels.

Technical view

CVE-2024-42223 affects the Linux kernel tda10048 DVB frontend driver. The source says state->xtal_hz can reach 16M and overflow when multiplied by pll_mfactor. Stable kernel commits fix the calculation by storing it in a 64-bit variable.

Likely exposure

Exposure is most likely limited to Linux systems running affected kernel builds where the tda10048 DVB frontend driver is present and relevant. Exact impact depends on kernel version, vendor backports, module configuration, and hardware use.

Exploitation context

The bundle marks KEV as false and provides no cited evidence of active exploitation. The available public description identifies an integer overflow but does not document exploitability, privilege requirements, or practical attack paths.

Researcher notes

The key technical detail is arithmetic width in the tda10048 driver. Public data lacks CVSS, CWE, exploit status, and concrete impact details, so assessment should stay tied to code reachability and vendor backport evidence.

Mitigation direction

  • Update to a vendor kernel containing the referenced stable fixes.
  • Check Debian LTS and other distributor advisories for backported packages.
  • Prioritize systems using DVB hardware or loading the tda10048 driver.
  • Disable or avoid unnecessary affected driver use where operationally safe.
  • Follow vendor guidance if no fixed kernel is available.

Validation and detection

  • Inventory kernel versions and vendor package build revisions.
  • Check whether the tda10048 driver is built, installed, or loaded.
  • Confirm the kernel source or package includes a referenced fix commit.
  • Review distributor advisories for backport status and affected releases.
  • Regression test DVB/media functionality after kernel update.
