SUNRPC: Fix UAF in svc_tcp_listen_data_ready()
Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Fix UAF in svc_tcp_listen_data_ready()
After the listener svc_sock is freed, and before invoking svc_tcp_accept()
for the established child sock, there is a window that the newsock
retaining a freed listener svc_sock in sk_user_data which cloning from
parent. In the race window, if data is received on the newsock, we will
observe use-after-free report in svc_tcp_listen_data_ready().
Reproduce by two tasks:
1. while :; do rpc.nfsd 0 ; rpc.nfsd; done
2. while :; do echo "" | ncat -4 127.0.0.1 2049 ; done

Fix the UAF by simply doing nothing in svc_tcp_listen_data_ready()
if state != TCP_LISTEN, that will avoid dereferencing svsk for all
child socket.

Title
ALSA: firewire-lib: Avoid division by zero in apply_constraint_to_size()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-lib: Avoid division by zero in apply_constraint_to_size()
The step variable is initialized to zero. It is changed in the loop,
but if it's not changed it will remain zero. Add a variable check
before the division.
The observed behavior was introduced by commit 826b5de90c0b
("ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size"),
and it is difficult to show that any of the interval parameters will
satisfy the snd_interval_test() condition with data from the
amdtp_rate_table[] table.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

This matches the AV:L used for the analogous device-supplied-config OOB in CVE-2024-53092.\nAC:L - The device simply advertises rss_max_key_size \u003e 40 and the overflow is deterministic on every probe \u2014 no race, no timing window, and the attacker picks the exact overflow length and (via ethtool set_rxfh) the exact bytes written past the array.\nPR:N - The out-of-bounds write and the BUG_ON panic occur automatically inside virtnet_probe()/virtnet_init_default_rss() during driver binding, and virtnet_commit_rss_command() DMAs the out-of-bounds key bytes back to the device on link-up, all with no guest account or credentials required.\nUI:N - Device probe, hotplug, and interface bring-up are driven automatically by the driver core and normal network configuration; no victim action is needed.\nS:U - The out-of-bounds read and write are confined to the guest kernel\u0027s own heap and security authority, with no IOMMU, hypervisor, or sandbox boundary crossed by the impact itself.\nC:H - virtnet_get_rxfh() memcpy\u0027s vi-\u003erss_key_size bytes from the 40-byte key array to userspace and virtnet_commit_rss_command() hands the same over-long buffer to the device, leaking adjacent virtnet_info heap contents including the indirection_table kernel pointer; once that pointer is overwritten via set_rxfh, get_rxfh reads back arbitrary kernel addresses.\nI:H - netdev_rss_key_fill() writes past key[] at probe and virtnet_set_rxfh()\u0027s memcpy(vi-\u003erss.key, rxfh-\u003ekey, vi-\u003erss_key_size) writes attacker-chosen bytes over the adjacent indirection_table pointer, after which vi-\u003erss.indirection_table[i] = rxfh-\u003eindir[i] is an arbitrary kernel write suitable for control-flow hijacking; on 6.1/6.6 key[] is the last struct member so the overflow lands directly on subsequent virtnet_info fields.\nA:H - netdev_rss_key_fill() contains BUG_ON(len \u003e 52), so any device advertising rss_max_key_size of 53\u2013255 panics the guest kernel outright during probe, and the corrupted indirection_table pointer additionally trips sg_set_buf()\u0027s virt_addr_valid BUG_ON and wild dereferences."

In 'hci_conn_del_sysfs()', 'device_unregister()' may be called when
an underlying (kobject) reference counter is greater than 1. This
means that reparenting (happened when the device is actually freed)
is delayed and, during that delay, parent controller device (hciX)
may be deleted. Since the latter may create a dangling pointer to
freed parent, avoid that scenario by reparenting to NULL explicitly.

Per kernel scoring guidance and repo precedent for BNEP/HIDP lifetime UAFs, Bluetooth reachability is Adjacent.\nAC:L - The attacker drives both halves of the lifetime race by repeatedly connecting and abruptly disconnecting, and connection teardown reliably reaches `hci_conn_del_sysfs()` with a non-rfcomm child still attached, leaving the dangling grandparent pointer every time. No condition depends on memory layout or state the attacker cannot influence.\nPR:N - The attacker is an unauthenticated adjacent Bluetooth device with no local account; the `capable(CAP_NET_ADMIN)` gate on `BNEPCONNADD` is satisfied by bluetoothd acting on the peer\u0027s behalf during normal PAN/HID service handling. This matches how the kernel CNA scored the comparable bnep/HIDP UAFs.\nUI:N - No victim action is needed \u2014 session teardown is triggered by the attacker\u0027s own disconnect, and controller unregistration occurs routinely via suspend/resume, USB dongle reset, firmware error recovery, or driver reload.\nS:U - The corrupted `hci_dev` object and the faulting code both live in the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - `device_for_each_child()` dereferences `dev-\u003ep` and walks `klist_children` inside the freed `hci_dev` slab, so an attacker who reclaims and sprays that large kmalloc allocation can steer the traversal to read arbitrary kernel memory.\nI:H - The traversal is not read-only \u2014 `klist_iter_init()` takes `spin_lock(\u0026k-\u003ek_lock)` and `kref_get()` increments refcounts through pointers taken from the freed object, yielding attacker-influenced writes and a classic UAF heap-corruption primitive suitable for control-flow hijack.\nA:H - Confirmed by the syzbot KASAN slab-use-after-free report; dereferencing the freed `hci_dev` and walking a stale klist produces a kernel oops or lockup, remotely inducible by an adjacent peer."

Since an invalid (without '\0' byte at all) byte sequence may be passed
from userspace, add an extra check to ensure that such a sequence is
rejected as possible ID and so never passed to 'kstrdup()' and further.

Title
BlueZ HID over GATT Profile Improper Access Control Remote Code Execution Vulnerability
Summary
BlueZ HID over GATT Profile Improper Access Control Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the implementation of the HID over GATT Profile. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-25177.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the implementation of the HID over GATT Profile. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of the current user.
