In the Linux kernel, the following vulnerability has been resolved: mm/vmalloc: prevent RCU stalls in kasan_release_vmalloc_node When CONFIG_PAGE_OWNER is enabled, freeing KASAN shadow pages during vmalloc cleanup triggers expensive stack unwinding that acquires RCU read locks. Processing a large purge_list without rescheduling can cause the task to hold CPU for extended periods (10+ seconds), leading to RCU stalls and potential OOM conditions. The issue manifests in purge_vmap_node() -> kasan_release_vmalloc_node() where iterating through hundreds or thousands of vmap_area entries and freeing their associated shadow pages causes: rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: rcu: Tasks blocked on level-0 rcu_node (CPUs 0-1): P6229/1:b..l ... task:kworker/0:17 state:R running task stack:28840 pid:6229 ... kasan_release_vmalloc_node+0x1ba/0xad0 mm/vmalloc.c:2299 purge_vmap_node+0x1ba/0xad0 mm/vmalloc.c:2299 Each call to kasan_release_vmalloc() can free many pages, and with page_owner tracking, each free triggers save_stack() which performs stack unwinding under RCU read lock. Without yielding, this creates an unbounded RCU critical section. Add periodic cond_resched() calls within the loop to allow: - RCU grace periods to complete - Other tasks to run - Scheduler to preempt when needed The fix uses need_resched() for immediate response under load, with a batch count of 32 as a guaranteed upper bound to prevent worst-case stalls even under light load.

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - mm/vmalloc: prevent RCU stalls in kasan_release_vmalloc_node When CONFIG_PAGE_OWNER is enabled, freeing     KASAN shadow pages during vmalloc cleanup triggers expensive stack unwinding that acquires RCU read locks.
    Processing a large purge_list without rescheduling can cause the task to hold CPU for extended periods     (10+ seconds), leading to RCU stalls and potential OOM conditions. The issue manifests in     purge_vmap_node() -> kasan_release_vmalloc_node() where iterating through hundreds or thousands of     vmap_area entries and freeing their associated shadow pages causes: rcu: INFO: rcu_preempt detected stalls     on CPUs/tasks: rcu: Tasks blocked on level-0 rcu_node (CPUs 0-1): P6229/1:b..l ... task:kworker/0:17     state:R running task stack:28840 pid:6229 ... kasan_release_vmalloc_node+0x1ba/0xad0 mm/vmalloc.c:2299     purge_vmap_node+0x1ba/0xad0 mm/vmalloc.c:2299 Each call to kasan_release_vmalloc() can free many pages,     and with page_owner tracking, each free triggers save_stack() which performs stack unwinding under RCU     read lock. Without yielding, this creates an unbounded RCU critical section. Add periodic cond_resched()     calls within the loop to allow: - RCU grace periods to complete - Other tasks to run - Scheduler to     preempt when needed The fix uses need_resched() for immediate response under load, with a batch count of     32 as a guaranteed upper bound to prevent worst-case stalls even under light load. (CVE-2026-43292)

Note that Nessus relies on the presence of the package as reported by the vendor.
