CVE-2026-97619

The Linux kernel contains a vulnerability in the io_uring subsystem regarding write accounting. Specifically, moving write accounting out of the kiocb completion handler and into io_req_rw_complete() task work creates a risk where dropping SB_FREEZE_WRITE protection depends on a task that may be ...

CVE-2026-97618

The Linux kernel contains a vulnerability in the io_uring/net subsystem where a recv/recvmsg operation using MSG_TRUNC causes the system to overconsume buffers. Specifically, if an incoming packet exceeds the provided buffer size, the net layer returns the full packet length instead of the number...

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Check resizedisabled before publishing the new subbuf order ringbuffersubbuforderset stores the new order and only then walks the CPUs, returning -EBUSY if any of them has resizing disabled. A user mapped buffer has...

CVE-2026-97617

A vulnerability exists in the Linux kernel 's ring-buffer mechanism. The ring_buffer_subbuf_order_set() function incorrectly stores a new order before checking if any CPUs have resizing disabled. Because __rb_map_vma() reads buffer->subbuf_order without holding the buffer->mutex, a race con...

CVE-2026-97617 ring-buffer: Check resize_disabled before publishing the new subbuf order

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Check resizedisabled before publishing the new subbuf order ringbuffersubbuforderset stores the new order and only then walks the CPUs, returning -EBUSY if any of them has resizing disabled. A user mapped buffer has...

CVE-2026-97616

The Linux kernel contains a memory leak vulnerability within the net/sched: act_api component. During a batched RTM_NEWACTION request, tcf_idr_check_alloc() takes a temporary reference on an action. If a subsequent action fails to initialize, tcf_action_destroy() uses strict release semantics tha...

CVE-2026-97616 net/sched: act_api: release all action references on NEWACTION failure

In the Linux kernel, the following vulnerability has been resolved: net/sched: actapi: release all action references on NEWACTION failure When a batched RTMNEWACTION request replaces an existing action, tcfidrcheckalloc takes a temporary reference on it. If a later action fails to initialize,...

CVE-2026-97615

The Linux kernel contains a vulnerability in the net: bridge component related to how CFM and MRP frame handlers are registered. Because these protocols registered a global br_frame_type whose hlist_node is linked into the per-bridge frame_type_list , enabling the protocol on multiple bridges ins...

CVE-2026-97613 net: mana: Reserve extra CQ slot for the fence completion CQE

In the Linux kernel, the following vulnerability has been resolved: net: mana: Reserve extra CQ slot for the fence completion CQE The RX completion queue is sized to hold exactly one CQE per posted RX WQE. MANAFENCERQ makes hardware post an additional CQERXOBJECTFENCE after the packet CQEs. The...

CVE-2026-97613

A vulnerability in the Linux kernel network subsystem involves improper sizing of the RX completion queue for MANA hardware. The current sizing fails to reserve an extra slot for the CQE_RX_OBJECT_FENCE posted by MANA_FENCE_RQ , which can cause the driver to drop the fence completion while holdin...

CVE-2026-97614

The Linux kernel contains a vulnerability in the net: dsa: tag_brcm component where the legacy FCS tagger fails to declare required tailroom. When a nonlinear skb reaches the tagger, it calculates the CRC over bytes starting at skb->data, causing it to read past the linear head into unrelated ...
