CVE-2024-43879
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: handle 2x996 RU allocation in cfg80211_calculate_bitrate_he() Currently NL80211_RATE_INFO_HE_RU_ALLOC_2x996 is not handled in cfg80211_calculate_bitrate_he(), leading to…
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
