skips pwq_dec_nr_active(), so an emptypwq can remain on pending_pwqs when its refcnt reaches zero.pwq_release_workfn() currently puts the pool before removing that pwq.If this drops the last pool reference, the pool can be RCU-freed whilethe pwq remains reachable, and node_activate_pending_pwq() may trylockthe freed pool-&gt;lock.\nRemove the pwq from pending_pwqs before putting the pool.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99103https://git.kernel.org/stable/c/6741dd3fd38e47c08bc39d11ef5fa141fa6d0441https://git.kernel.org/stable/c/9f5d5aef3072a33c6f9bfb954bb0cba1c2541849https://git.kernel.org/stable/c/f320b85c90fe5fc9d4d06badd450518323a94a7fhttps://git.kernel.org/stable/c/3d2ef2b9f4c084ab498494d26495a82f7e15407bhttps://git.kernel.org/stable/c/cf9c8aaea0d47410df8708bec195889f3a85cd3c#kernel
