https://notcve.org/view.php?id=CVE-2024-56657
27 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: ALSA: control: Avoid WARN() for symlink errors Using WARN() for showing the error of symlink creations don't give more information than telling that something goes wrong, since the usual code path is a lregister callback from each control element creation. More badly, the use of WARN() rather confuses fuzzer as if it were serious issues. This patch downgrades the warning messages to use the normal dev_err() instead of WARN().

27 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: net: enetc: Do not configure preemptible TCs if SIs do not support Both ENETC PF and VF drivers share enetc_setup_tc_mqprio() to configure MQPRIO. And enetc_setup_tc_mqprio() calls enetc_change_preemptible_tcs() to configure preemptible TCs. However, only PF is able to configure preemptible TCs. Because only PF has related registers, while VF does not have these registers. So for VF, its hw->port pointer is NULL. • https://git.kernel.org/stable/c/827145392a4aad635b93e5235b7d7fecc2fa31c7 •
