Description
In the Linux kernel, the following vulnerability has been resolved:
staging: wfx: fix an error handling in wfx_init_common()
One error handler of wfx_init_common() return without calling ieee80211_free_hw(hw), which may result in memory leak. And I add one err label to unify the error handler, which is useful for the subsequent changes.
Statement
This vulnerability is rated as Moderate severity because triggering the resource leak requires local access to induce hardware initialization failures, limiting the blast radius to a localized denial of service. The affected staging driver for Silicon Labs wireless hardware is not enabled in supported Red Hat Enterprise Linux kernels. Consequently, default Red Hat deployments are not exposed to this flaw.
