page_pool_recycle_in_ring ptr_ring_produce spin_lock(&r->producer_lock);
WRITE_ONCE(r->queue[r->producer++], ptr) //recycle last page to pool page_pool_release page_pool_scrub
page_pool_empty_ring ptr_ring_consume page_pool_return_page //release all page __page_pool_destroy
free_percpu(pool->recycle_stats); free(pool) //free spin_unlock(&r->producer_lock); //pool->ring uaf read
recycle_stat_inc(pool, ring); page_pool can be free while page pool recycle the last page in ring. Add
producer-lock barrier to page_pool_release to prevent the page pool from being free before all pages have
been recycled. recycle_stat_inc() is empty when CONFIG_PAGE_POOL_STATS is not enabled, which will trigger
Wempty-body build warning. Add definition for pool stat macro to fix warning. (CVE-2025-38129)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.521.74 or later.
