Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Linux/Linux.
  2. 2Review the reported fix. Update Linux/Linux to 4e0a67fbe3d9e2e1d6f81dfc607184c6b0abd3dd; Linux/Linux to 0ec1d14cf302ae7c23ec218527b2849a1fced3f4; Linux/Linux to 5f47c9bc4a62e61f932a83680a796bc09ae48dd3; Linux/Linux to 62f8c28a0fb08611e1278ab2af964550e22aac3c if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: clean up color-change beacon data on errors nl80211_color_change() calls nl80211_parse_beacon() for the beacon_next template, which can allocate params.beacon_next.mbssid_ies and .rnr_ies. A parsing failure returned directly instead of using the out: cleanup, leaking any allocations completed before the error. Allocate the nested attribute table before parsing beacon_next. Its allocation failure can then return before beacon data exists, while a later parsing failure uses out: to release the parsed data.
