    KVM: arm64: Fix pin leak and publication ordering in __pkvm_init_vcpu()

    In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix pin leak and publication ordering in __pkvm_init_vcpu() Two bugs exist in the vCPU initialisation path: 1. If a check fails after hyp_pin_shared_mem() succeeds, the cleanup path jumps to 'unlock' without calling unpin_host_vcpu() or unpin_host_sve_state(), permanently leaking pin references on the host vCPU and SVE state pages. Extract a register_hyp_vcpu() helper that performs the checks and the store. When register_hyp_vcpu() returns an error, call unpin_host_vcpu() and unpin_host_sve_state() inline before falling through to the exis

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

    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 un

    RDMA/rxe: Reject unknown opcodes before ICRC processing

    In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Reject unknown opcodes before ICRC processing Even after applying commit 7244491dab34 ("RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv"), a single unauthenticated UDP packet can still trigger panic. That patch handled payload_size() underflow only for valid opcodes with short packets, not for packets carrying an unknown opcode. The unknown-opcode OOB read described below predates that commit and reaches back to the initial Soft RoCE driver. The check added there reads pkt->paylen < header_size(pkt) + bth_pad(pkt) + RXE_ICRC_SIZE where he

    ipmi: Check event message buffer response for bad data

    In the Linux kernel, the following vulnerability has been resolved: ipmi: Check event message buffer response for bad data The event message buffer response data size got checked later when processing, but check it right after the response comes back. It appears some BMCs may return an empty message instead of an error when fetching events. There are apparently some new BMCs that make this error, so we need to compensate.

    In the Linux kernel, the following vulnerability has been resolved: RDMA/ocrdma: Don't NULL deref uctx on errors in ocrdma_copy_pd_uresp() Sashiko points out that pd->uctx isn't initialized until late in the function so all these error flow references are NULL and will crash. Use the uctx that isn't NULL.

    wifi: b43: enforce bounds check on firmware key index in b43_rx()

    In the Linux kernel, the following vulnerability has been resolved: wifi: b43: enforce bounds check on firmware key index in b43_rx() The firmware-controlled key index in b43_rx() can exceed the dev->key[] array size (58 entries). The existing B43_WARN_ON is non-enforcing in production builds, allowing an out-of-bounds read. Make the B43_WARN_ON check enforcing by dropping the frame when the firmware returns an invalid key index.

    ip6_gre: Use cached t->net in ip6erspan_changelink().

    In the Linux kernel, the following vulnerability has been resolved: ip6_gre: Use cached t->net in ip6erspan_changelink(). After commit 5e72ce3e3980 ("net: ipv6: Use link netns in newlink() of rtnl_link_ops"), ip6erspan_newlink() correctly resolves the per-netns ip6gre hash via link_net. ip6erspan_changelink() was not converted in that series and still uses dev_net(dev), which diverges from the device's creation netns after IFLA_NET_NS_FD migration. This re-inserts the tunnel into the wrong per-netns hash. The original netns keeps a stale entry. When that netns is later destroyed, ip6gre_exit_rtnl_net() walks the stale entry, producing a sl

    libceph: Fix slab-out-of-bounds access in auth message processing

    In the Linux kernel, the following vulnerability has been resolved: libceph: Fix slab-out-of-bounds access in auth message processing If a (potentially corrupted) message of type CEPH_MSG_AUTH_REPLY contains a positive value in its result field, it is treated as an error code by ceph_handle_auth_reply() and returned to handle_auth_reply(). Thereafter, an attempt is made to send the preallocated message of type CEPH_MSG_AUTH, where the returned value is interpreted as the size of the front segment to send. If the result value in the message is greater than the size of the memory buffer allocated for the front segment, an out-of-bounds access

    KVM: x86: Fix shadow paging use-after-free due to unexpected GFN

    In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN The shadow MMU computes GFNs for direct shadow pages using sp->gfn plus the SPTE index. This assumption breaks for shadow paging if the guest page tables are modified between VM entries (similar to commit aad885e77496, "KVM: x86/mmu: Drop/zap existing present SPTE even when creating an MMIO SPTE", 2026-03-27). The flow is as follows: - a PDE is installed for a 2MB mapping, and a page in that area is accessed. KVM creates a kvm_mmu_page consisting of 512 4KB pages; the kvm_mmu_page is marked by FNAME(fet

    In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix unlocked call to hns_roce_qp_remove() Sashiko points out that hns_roce_qp_remove() requires the caller to hold locks. The error flow in hns_roce_create_qp_common() doesn't hold those locks for the error unwind so it risks corrupting memory. Grab the same locks the other two callers use.

    dm-thin: fix metadata refcount underflow

    In the Linux kernel, the following vulnerability has been resolved: dm-thin: fix metadata refcount underflow There's a bug in dm-thin in the function rebalance_children. If the internal btree node has one entry, the code tries to copy all btree entries from the node's child to the node itself and then decrement the child's reference count. If the child node is shared (it has reference count > 1), we won't free it, so there would be two pointers to each of the grandchildren nodes. But the reference counts of the grandchildren is not increased, thus the reference count doesn't match the number of pointers that point to the grandchildren. Thi

    can: ucan: fix devres lifetime

    In the Linux kernel, the following vulnerability has been resolved: can: ucan: fix devres lifetime USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers are unbound without their devices being physically disconnected (e.g. on probe deferral or configuration changes). Fix the control message buffer lifetime so that it is released on driver unbind.

    net: strparser: fix skb_head leak in strp_abort_strp()

    In the Linux kernel, the following vulnerability has been resolved: net: strparser: fix skb_head leak in strp_abort_strp() When the stream parser is aborted, for example after a message assembly timeout, it can still hold a reference to a partially assembled message in strp->skb_head. That skb is not released in strp_abort_strp(), which leaks the partially assembled message and can be triggered repeatedly to exhaust memory. Fix this by freeing strp->skb_head and resetting the parser state in the abort path. Leave strp_stop() unchanged so final cleanup still happens in strp_done() after the work and timer have been synchronized.

    net: caif: clear client service pointer on teardown

    In the Linux kernel, the following vulnerability has been resolved: net: caif: clear client service pointer on teardown `caif_connect()` can tear down an existing client after remote shutdown by calling `caif_disconnect_client()` followed by `caif_free_client()`. `caif_free_client()` releases the service layer referenced by `adap_layer->dn`, but leaves that pointer stale. When the socket is later destroyed, `caif_sock_destructor()` calls `caif_free_client()` again and dereferences the freed service pointer. Clear the client/service links before releasing the service object so repeated teardown becomes harmless.
