CVE-2026-46125 (GCVE-0-2026-46125)

Vulnerability from cvelistv5 – Published: 2026-05-28 09:35 – Updated: 2026-06-19 11:59

Title

wifi: mac80211: remove station if connection prep fails

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: remove station if connection prep fails If connection preparation fails for MLO connections, then the interface is completely reset to non-MLD. In this case, we must not keep the station since it's related to the link of the vif being removed. Delete an existing station. Any "new_sta" is already being removed, so that doesn't need changes. This fixes a use-after-free/double-free in debugfs if that's enabled, because a vif going from MLD (and to MLD, but that's not relevant here) recreates its entire debugfs.

Severity

8.8 (High)

CVE-2026-46135 (GCVE-0-2026-46135)

Vulnerability from cvelistv5 – Published: 2026-05-28 09:35 – Updated: 2026-06-15 08:03

Title

nvmet-tcp: fix race between ICReq handling and queue teardown

Summary

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: fix race between ICReq handling and queue teardown nvmet_tcp_handle_icreq() updates queue->state after sending an Initialization Connection Response (ICResp), but it does so without serializing against target-side queue teardown. If an NVMe/TCP host sends an Initialization Connection Request (ICReq) and immediately closes the connection, target-side teardown may start in softirq context before io_work drains the already buffered ICReq. In that case, nvmet_tcp_schedule_release_queue() sets queue->state to NVMET_TCP_Q_DISCONNECTING and drops the queue reference under state_lock. If io_work later processes that ICReq, nvmet_tcp_handle_icreq() can still overwrite the state back to NVMET_TCP_Q_LIVE. That defeats the DISCONNECTING-state guard in nvmet_tcp_schedule_release_queue() and allows a later socket state change to re-enter teardown and issue a second kref_put() on an already released queue. The ICResp send failure path has the same problem. If teardown has already moved the queue to DISCONNECTING, a send error can still overwrite the state with NVMET_TCP_Q_FAILED, again reopening the window for a second teardown path to drop the queue reference. Fix this by serializing both post-send state transitions with state_lock and bailing out if teardown has already started. Use -ESHUTDOWN as an internal sentinel for that bail-out path rather than propagating it as a transport error like -ECONNRESET. Keep nvmet_tcp_socket_error() setting rcv_state to NVMET_TCP_RECV_ERR before honoring that sentinel so receive-side parsing stays quiesced until the existing release path completes.

In that case, nvmet_tcp_schedule_release_queue()\nsets queue-\u003estate to NVMET_TCP_Q_DISCONNECTING and drops the queue\nreference under state_lock.\n\nIf io_work later processes that ICReq, nvmet_tcp_handle_icreq() can\nstill overwrite the state back to NVMET_TCP_Q_LIVE. That defeats the\nDISCONNECTING-state guard in nvmet_tcp_schedule_release_queue() and\nallows a later socket state change to re-enter teardown and issue a\nsecond kref_put() on an already released queue.\n\nThe ICResp send failure path has the same problem. If teardown has\nalready moved the queue to DISCONNECTING, a send error can still\noverwrite the state with NVMET_TCP_Q_FAILED, again reopening the\nwindow for a second teardown path to drop the queue reference.\n\nFix this by serializing both post-send state transitions with\nstate_lock and bailing out if teardown has already started.\n\nUse -ESHUTDOWN as an internal sentinel for that bail-out path rather\nthan propagating it as a transport error like -ECONNRESET. Keep\nnvmet_tcp_socket_error() setting rcv_state to NVMET_TCP_RECV_ERR before\nhonoring that sentinel so receive-side parsing stays quiesced until the\nexisting release path completes."

CVE-2026-46145 (GCVE-0-2026-46145)

Vulnerability from cvelistv5 – Published: 2026-05-28 09:36 – Updated: 2026-06-14 17:57

Title

RDMA/mana: Validate rx_hash_key_len

Summary

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validate rx_hash_key_len Sashiko points out that rx_hash_key_len comes from a uAPI structure and is blindly passed to memcpy, allowing the userspace to trash kernel memory. Bounds check it so the memcpy cannot overflow.

Severity

7.8 (High)

CVE-2026-46152 (GCVE-0-2026-46152)

Title

wifi: mac80211: drop stray 'static' from fast-RX rx_result

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: drop stray 'static' from fast-RX rx_result ieee80211_invoke_fast_rx() is documented as safe for parallel RX, but its per-invocation rx_result is declared static. Concurrent callers then share one instance and can overwrite each other's result between ieee80211_rx_mesh_data() and the switch on res. That can make a packet that was queued or consumed by ieee80211_rx_mesh_data() fall through into ieee80211_rx_8023(), or make a packet that should continue return as queued. Make res an automatic variable so each invocation keeps its own result.

Severity

8.8 (High)

wifi: mac80211: use safe list iteration in radar detect work

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: use safe list iteration in radar detect work The call to ieee80211_dfs_cac_cancel can cause the iterated chanctx to be freed and removed from the list. Guard against this to avoid a slab-use-after-free error.

CVE-2026-46173 (GCVE-0-2026-46173)

Vulnerability from cvelistv5 – Published: 2026-05-28 09:36 – Updated: 2026-06-17 06:15

Title

exit: prevent preemption of oopsing TASK_DEAD task

Summary

In the Linux kernel, the following vulnerability has been resolved: exit: prevent preemption of oopsing TASK_DEAD task When an already-exiting task oopses, make_task_dead() currently calls do_task_dead() with preemption enabled. That is forbidden: do_task_dead() calls __schedule(), which has a comment saying "WARNING: must be called with preemption disabled!". If an oopsing task is preempted in do_task_dead(), between becoming TASK_DEAD and entering the scheduler explicitly, bad things happen: finish_task_switch() assumes that once the scheduler has switched away from a TASK_DEAD task, the task can never run again and its stack is no longer needed; but that assumption apparently doesn't hold if the dead task was preempted (the SM_PREEMPT case). This means that the scheduler ends up repeatedly dropping references on the dead task's stack, which can lead to use-after-free or double-free of the entire task stack; in other words, two tasks can end up running on the same stack, resulting in various kinds of memory corruption. (This does not just affect "recursively oopsing" tasks; it is enough to oops once during task exit, for example in a file_operations::release handler)

Severity

7.8 (High)

CVE-2026-46331 (GCVE-0-2026-46331)

Vulnerability from cvelistv5 – Published: 2026-06-16 06:26 – Updated: 2026-06-19 12:00

Title

net/sched: fix pedit partial COW leading to page cache corruption

Summary

In the Linux kernel, the following vulnerability has been resolved: net/sched: fix pedit partial COW leading to page cache corruption tcf_pedit_act() computes the COW range for skb_ensure_writable() once before the key loop using tcfp_off_max_hint, but the hint does not account for the runtime header offset added by typed keys. This can leave part of the write region un-COW'd. Fix by moving skb_ensure_writable() inside the per-key loop where the actual write offset is known, and add overflow checking on the offset arithmetic. For negative offsets (e.g. Ethernet header edits at ingress), use skb_cow() to COW the headroom instead. Guard offset_valid() against INT_MIN, where negation is undefined.

This\ncan leave part of the write region un-COW\u0027d.\n\nFix by moving skb_ensure_writable() inside the per-key loop where\nthe actual write offset is known, and add overflow checking on the\noffset arithmetic. For negative offsets (e.g. Ethernet header edits\nat ingress), use skb_cow() to COW the headroom instead. Guard\noffset_valid() against INT_MIN, where negation is undefined."
