    net/sched: sch_dualpi2: Do not call qdisc_tree_reduce_backlog during peek before restoring qlen

    In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_dualpi2: Do not call qdisc_tree_reduce_backlog during peek before restoring qlen Whenever dualpi2 drops packets during peek, it calls qdisc_tree_reduce_backlog. An issue arises because it calls qdisc_tree_reduce_backlog before it reincrements the qlen. If qlen drops to zero, but peek returns an skb, the parent's qlen_notify callback will be executed even though dualpi2 still has 1 packet on the queue and, thus, mistakenly deactivates the parent's class which leads to a null-ptr-deref: [ 101.427314][ T599] Oops: general protection fault, probably for non-ca

    net: mana: initialize gdma queue id to INVALID_QUEUE_ID

    In the Linux kernel, the following vulnerability has been resolved: net: mana: initialize gdma queue id to INVALID_QUEUE_ID mana_gd_create_mana_wq_cq() leaves queue->id as 0 (from kzalloc_obj()) until mana_create_wq_obj() assigns the firmware-returned id. If creation fails before that, cleanup calls mana_gd_destroy_cq() with id 0, NULLing gc->cq_table[0] and silently breaking whichever real CQ owns that slot. Initialize queue->id to INVALID_QUEUE_ID right after allocation, matching mana_gd_create_eq(). The existing (id >= max_num_cqs) guard then short-circuits cleanly.

    net: watchdog: fix refcount tracking races

    In the Linux kernel, the following vulnerability has been resolved: net: watchdog: fix refcount tracking races Blamed commit converted the untracked dev_hold()/dev_put() calls in the watchdog code to use the tracked dev_hold_track()/dev_put_track() (which were later renamed/interfaced to netdev_hold() and netdev_put()). By introducing dev->watchdog_dev_tracker to store the reference tracking information without adding synchronization between netdev_watchdog_up() and dev_watchdog(), it enabled the race condition where this pointer could be overwritten or freed concurrently, leading to the list corruption crash syzbot reported: list_del cor

    net: wwan: t7xx: check skb_clone in control TX

    In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: check skb_clone in control TX t7xx_port_ctrl_tx() clones each skb fragment before passing it to the port transmit path. The clone is used immediately to set cloned->len, so an skb_clone() failure results in a NULL pointer dereference. Check the clone before using it. If previous fragments were already queued, preserve the driver's existing partial-write behavior by returning the number of bytes submitted so far.

    kcm: use WRITE_ONCE() when changing lower socket callbacks

    In the Linux kernel, the following vulnerability has been resolved: kcm: use WRITE_ONCE() when changing lower socket callbacks kcm_attach() replaces a live lower TCP socket's sk_data_ready and sk_write_space callbacks with KCM handlers, and kcm_unattach() restores them later. Those callback-pointer updates are still plain stores even though the same fields can be read and invoked concurrently on other CPUs. If another CPU observes an older callback snapshot after the live field has already been restored, callback execution can run with a mismatched target and sk_user_data state, leading to stale or misdirected wakeups. Use WRITE_ONCE() fo

    ALSA: seq: avoid stale FIFO cells during resize

    In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: avoid stale FIFO cells during resize snd_seq_fifo_resize() still needs to publish the replacement pool before it waits for FIFO users. A blocking snd_seq_read() holds f->use_lock while it sleeps, so concurrent senders must be able to queue to the new pool and wake that reader instead of failing against a closing old pool. However, snd_seq_fifo_event_in() duplicates an event before it takes f->lock, and snd_seq_read() can dequeue a cell and later call snd_seq_fifo_cell_putback() if copy_to_user() or snd_seq_expand_var_event() fails. If resize swaps f->pool and de

    netfilter: nf_dup_netdev: add nf_dev_xmit_recursion*() helpers and use them

    In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_dup_netdev: add nf_dev_xmit_recursion*() helpers and use them Update nft_dup and nft_fwd to use the nf_dev_xmit_recursion() helpers. This patch also disables BH when transmitting the skb to address a possible migration to different CPU leading to imbalanced decrementation of the recursion counters. This is modeled after Florian Westphal's dev_xmit_recursion*() API available since commit 97cdcf37b57e ("net: place xmit recursion in softnet data") according to its current state in the tree.

    sockmap: Fix use-after-free in udp_bpf_recvmsg()

    In the Linux kernel, the following vulnerability has been resolved: sockmap: Fix use-after-free in udp_bpf_recvmsg() syzbot reported use-after-free of struct sk_msg in sk_msg_recvmsg(). [0] sk_msg_recvmsg() peeks sk_msg from psock->ingress_msg under a lock, but its processing is lockless. Thus, sk_msg_recvmsg() must be serialised by callers, otherwise multiple threads could touch the same sk_msg. For example, TCP uses lock_sock(), and AF_UNIX uses unix_sk(sk)->iolock. Initially, udp_bpf_recvmsg() had used lock_sock(), but the cited commit removed it. Let's serialise sk_msg_recvmsg() with lock_sock() in udp_bpf_recvmsg(). Note that hol

    tipc: fix UAF in tipc_l2_send_msg()

    In the Linux kernel, the following vulnerability has been resolved: tipc: fix UAF in tipc_l2_send_msg() Syzbot reported a slab-use-after-free in ipvlan_hard_header() when called from tipc_l2_send_msg(). The root cause is that tipc_disable_l2_media() calls synchronize_net() while b->media_ptr is still valid. This allows concurrent RCU readers to obtain the device pointer after synchronize_net() has finished. The pointer is cleared later in bearer_disable(), but without any subsequent synchronization, allowing the device to be freed while still in use by readers. Fix this by clearing b->media_ptr in tipc_disable_l2_media() before calling sy

    tcp: ipv6: clamp default adverting MSS to avoid GSO_BY_FRAGS (0xFFFF)

    In the Linux kernel, the following vulnerability has been resolved: tcp: ipv6: clamp default adverting MSS to avoid GSO_BY_FRAGS (0xFFFF) When MTU is large, ip6_default_advmss() can return IPV6_MAXPLEN (65535). This is interpreted by TCP as mss_clamp, allowing the MSS to reach 65535. However, 0xFFFF is also used as a magic value GSO_BY_FRAGS in the kernel. If a TCP packet with gso_size=0xFFFF is passed to skb_segment(), it will be mistakenly treated as GSO_BY_FRAGS, leading to a NULL pointer dereference because local TCP packets do not use frag_list. Fix this by returning min(IPV6_MAXPLEN, GSO_BY_FRAGS - 1) (65534) from ip6_default_advmss

An earlier patch by Gui-Dong Han <hanguidong02@gmail.com> attempted to fix this by adding the missing memory barriers. Rather than adding the barriers, this patch replaces the waitqueue+flag with a completion, which is designed for this exact purpose.
