    fs/ntfs3: resize log->one_page_buf when adopting on-disk page size

    In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: resize log->one_page_buf when adopting on-disk page size log_replay() allocates log->one_page_buf using the page size that was chosen from the host PAGE_SIZE: log->one_page_buf = kmalloc(log->page_size, GFP_NOFS); Later, when a restart area is found, the log page size recorded on disk is adopted: t32 = le32_to_cpu(log->rst_info.r_page->sys_page_size); if (log->page_size != t32) { log->l_size = log->orig_file_size; log->page_size = norm_file_page(t32, &log->l_size, t32 == DefaultLogPageSize); } If the on-disk page size is larger than the size used

    xprtrdma: Fix ep kref imbalance on ADDR_CHANGE

    In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Fix ep kref imbalance on ADDR_CHANGE rpcrdma_cm_event_handler() falls through to the disconnected: label on RDMA_CM_EVENT_ADDR_CHANGE and calls rpcrdma_ep_put() with no matching get when the event arrives before RDMA_CM_EVENT_ESTABLISHED. The kref then underflows during connect teardown and rpcrdma_xprt_disconnect() operates on a freed ep. Reference counts across a normal connection lifecycle: rpcrdma_ep_create() kref_init ->1 rpcrdma_xprt_connect() ep_get ->2 (before post_recvs) RDMA_CM_EVENT_ESTABLISHED ep_get

    xprtrdma: Initialize re_id before removal registration

    In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Initialize re_id before removal registration rpcrdma_create_id() registers ep->re_rn with the rpcrdma ib_client before returning the new rdma_cm_id to rpcrdma_ep_create(). However rpcrdma_ep_create() currently stores that pointer in ep->re_id only after rpcrdma_create_id() returns. A local administrator can race an NFS/RDMA mount against RDMA device removal. If rpcrdma_remove_one() observes the just-registered notification before rpcrdma_ep_create() assigns ep->re_id, rpcrdma_ep_removal_done() calls trace_xprtrdma_device_removal(NULL). The tracepoint dereferences

    xprtrdma: Check frwr_wp_create() during connect

    In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Check frwr_wp_create() during connect frwr_wp_create() creates the singleton Memory Region used to encode padding for Write chunks whose payload length is not XDR-aligned. Its failure paths return a negative errno and leave ep->re_write_pad_mr set to NULL. rpcrdma_xprt_connect() currently ignores that return value. If frwr_wp_create() fails after the rest of the connection setup succeeds, xprt_rdma_connect_worker() treats the connection attempt as successful and sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned receive page length reaches rpcrd

    xprtrdma: Fix bcall rep leak and unbounded peek

    In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Fix bcall rep leak and unbounded peek rpcrdma_is_bcall() decodes a reply's first words to decide whether the frame is a backchannel call. Two issues in that decode path let a short or malformed reply leak the receive buffer and drain the Receive queue. First, the speculative peek p = xdr_inline_decode(xdr, 0); /* five p++ reads follow */ asks xdr_inline_decode() for zero bytes, which returns xdr->p without consulting xdr->end. The five subsequent __be32 reads can then walk up to 20 bytes past the wire payload into stale regbuf contents and misclassify t

    xprtrdma: Repost Receive buffers for malformed replies

    In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Repost Receive buffers for malformed replies rpcrdma_wc_receive() decrements the transport's Receive count for every completion before it dispatches a successful Receive to rpcrdma_reply_handler(). The handler must post a replacement Receive WR before returning unless ownership of the rep has moved elsewhere, as on the backchannel path. Commit 2ae50ad68cd7 ("xprtrdma: Close window between waking RPC senders and posting Receives") moved the Receive refill out of rpcrdma_wc_receive(), where it had run ahead of every reply, into rpcrdma_reply_handler() so that the r

    apparmor: fix race in unix socket mediation when peer_path is used

    In the Linux kernel, the following vulnerability has been resolved: apparmor: fix race in unix socket mediation when peer_path is used The holding a reference to the peer_sk is not enough to ensure access to the peer sk path. Accessing the path outside of the state lock allows for a race with unix_release_sock(). Fix this by taking the state lock and getting a reference to the path under lock. Ideally for connected sockets we would cache this information so we don't have to take the lock here. But for now just fix the race.

    In the Linux kernel, the following vulnerability has been resolved: apparmor: fix refcount leak when updating the sk_ctx Currently update_sk_ctx() transfers the plabel reference, unfortunately it is also unconditionally put in the caller. Ideally we would make the caller conditionally put the reference based on whether it was transferred but for now just fix the bug by getting a reference.

    apparmor: check label build before no_new_privs test

    In the Linux kernel, the following vulnerability has been resolved: apparmor: check label build before no_new_privs test aa_change_profile() builds a replacement label with fn_label_build_in_scope() before the no_new_privs subset check. The build helper can fail and return NULL or an ERR_PTR, but the result was passed to aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL() check. Reuse the existing target-label build failure handling immediately after the build. This preserves the current audit handling while preventing the subset helper from dereferencing an invalid label.

    apparmor: aa_label_alloc use aa_label_free on alloc failure

    In the Linux kernel, the following vulnerability has been resolved: apparmor: aa_label_alloc use aa_label_free on alloc failure aa_label_alloc() allocates a secid before allocating or taking the label proxy. If the later proxy step fails, the error path only freed the label memory, leaking any resources initialized by aa_label_init(). Use aa_label_free() on the failure path so partially initialized labels release their secid and other label resources before the backing memory is freed.

    In the Linux kernel, the following vulnerability has been resolved: apparmor: fail policy unpack on accept2 allocation failure unpack_pdb() may need to allocate a missing ACCEPT2 table for older policy data. If that allocation failed, it set an error message but jumped to the success path, returning a policydb with the required table missing. Return -ENOMEM through the normal failure path when the ACCEPT2 allocation fails. Remove the now-unused out label.

    i3c: mipi-i3c-hci: Fix race in i3c_hci_addr_to_dev()

    In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Fix race in i3c_hci_addr_to_dev() i3c_hci_addr_to_dev() walks bus->devs.i3c, which is protected by bus.lock (rwsem). However, it is invoked from the MIPI I3C HCI IRQ handler, which cannot take bus.lock. This allows concurrent device addition/removal in the I3C core to modify the list while it is being traversed, potentially leading to use-after-free or crashes. Remove the dependency on the bus device list and introduce a dedicated lookup table. Add an ibi_devs[] array indexed by DAT entry, maintained under hci->lock. Update the array when IBIs are en

    xfrm: Fix xfrm state cache insertion race

    In the Linux kernel, the following vulnerability has been resolved: xfrm: Fix xfrm state cache insertion race The xfrm input state cache insertion code checks the validity of the state before acquiring the global xfrm_state_lock. Thus it's possible for someone else to kill the state after it passed the validity check, and then the insertion will add the dead state to the cache. Fix this by moving the validity check inside the lock. This entire function is called on the input path, where BH must be off (e.g., the caller of this function xfrm_input acquires its spinlocks without disabling BH). So there is no need to disable BH here or tak

The list head is left pointing at freed kmalloc-96 objects. A second AMDKFD_IOC_CRIU_OP from the same process re-enters: list_empty() reads the dangling ->next (use-after-free), the loop walks freed entries, and each is kfree()'d again (double-free). This is reachable by an unprivileged render-group user via /dev/kfd with no capabilities required. Add list_del()

    sctp: hold socket lock when dumping endpoints in sctp_diag

    In the Linux kernel, the following vulnerability has been resolved: sctp: hold socket lock when dumping endpoints in sctp_diag SCTP_DIAG endpoint dumping was traversing endpoint address lists without holding lock_sock(), while those lists could change concurrently via socket operations (e.g., bindx changes). This creates a race where nla_reserve() counts addresses under RCU protection, but the subsequent copy may see fewer entries, potentially leaking uninitialized memory to userspace. Fix this by: - Taking a reference on each endpoint during hash traversal - Moving socket operations (lock_sock()) outside read_lock_bh() - Serializing addr
