Title
smc: Fix use-after-free in __pnet_find_base_ndev().
Summary
In the Linux kernel, the following vulnerability has been resolved:
smc: Fix use-after-free in __pnet_find_base_ndev().
syzbot reported use-after-free of net_device in __pnet_find_base_ndev(),
which was called during connect(). [0]
smc_pnet_find_ism_resource() fetches sk_dst_get(sk)->dev and passes
down to pnet_find_base_ndev(), where RTNL is held. Then, UAF happened
at __pnet_find_base_ndev() when the dev is first used.
This means dev had already been freed before acquiring RTNL in
pnet_find_base_ndev().
While dev is going away, dst->dev could be swapped with blackhole_netdev,
and the dev's refcnt by dst will be released.
We must hold dev's refcnt before calling smc_pnet_find_ism_resource().
Also, smc_pnet_find_roce_resource() has the same problem.
Let's use __sk_dst_get() and dst_dev_rcu() in the two functions.

Title
pps: fix warning in pps_register_cdev when register device fail
Summary
In the Linux kernel, the following vulnerability has been resolved:
pps: fix warning in pps_register_cdev when register device fail
Similar to previous commit 2a934fdb01db ("media: v4l2-dev: fix error
handling in __video_register_device()"), the release hook should be set
before device_register(). Otherwise, when device_register() return error
and put_device() try to callback the release function, the below warning
may happen.

Before commit c79a39dc8d06 ("pps: Fix a use-after-free"),
pps_register_cdev() call device_create() to create pps->dev, which will
init dev->release to device_create_release(). Now the comment is outdated,
just remove it.
Thanks for the reminder from Calvin Owens, 'kfree_pps' should be removed
in pps_register_source() to avoid a double free in the failure case.

No local access is required to reach the vulnerable code.\nAC:L - An attacker can flood fragmented IPv4 datagrams and ICMP-error-provoking packets continuously, keeping `ip_defrag()` and `icmpv4_xrlim_allow()` executing on the unprotected `dst-\u003edev` fetch at very high rates, so the window is sampled constantly rather than once; on the common deployments where the dst-device teardown is routine and attacker-influenceable (PPPoE/L2TP session churn on a BRAS, tunnel and virtual-interface teardown in cloud/container hosts, route-exception churn the attacker drives with ICMP redirect and PMTU messages), the race is repeatable at will rather than dependent on a condition the attacker cannot reach.\nPR:N - ICMP echo replies and IPv4 fragment reassembly are handled before any authentication or authorization step exists, and there is no capability check anywhere on the path from packet receive to the unprotected `dst-\u003edev` dereference. Any unauthenticated host that can send IP packets to the target reaches this code.\nUI:N - The vulnerable code executes entirely in softirq context on packet receive and in the ICMP/multicast transmit paths; no local user or administrator has to open, mount, or click anything.\nS:U - The stale dereference and any resulting corruption stay inside the kernel\u0027s own memory and the network stack, which is a single security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Reading a freed `struct net_device` yields `dev-\u003eflags` and, through `l3mdev_master_ifindex_rcu()`, an rcu-dereferenced walk of the upper-device list and a master ifindex, all taken from reclaimed memory; an attacker who grooms the slab into that allocation gets kernel memory interpreted as device state and used to select fragment-reassembly queues and ICMP peer entries, enabling disclosure of kernel memory.\nI:H - The garbage ifindex derived from the freed device becomes the `vif` key for `ip_find()`, steering fragment reassembly into attacker-chosen queues, and the same freed-object pointer feeds `inet_getpeer_v4()`; a use-after-free of a `net_device` of this class is leverageable via heap spraying into controlled kernel writes and control-flow hijack.\nA:H - Dereferencing a released `net_device` and following its upper-device list pointers into freed memory produces an oops or panic in softirq context, taking down the entire system, and it is triggerable by ordinary remote traffic."

Title
net/sched: sch_qfq: Fix null-deref in agg_dequeue
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_qfq: Fix null-deref in agg_dequeue
To prevent a potential crash in agg_dequeue (net/sched/sch_qfq.c)
when cl->qdisc->ops->peek(cl->qdisc) returns NULL, we check the return
value before using it, similar to the existing approach in sch_hfsc.c.
To avoid code duplication, the following changes are made:
1. Changed qdisc_warn_nonwc(include/net/pkt_sched.h) into a static
inline function.
2. Moved qdisc_peek_len from net/sched/sch_hfsc.c to
include/net/pkt_sched.h so that sch_qfq can reuse it.
3. Applied qdisc_peek_len in agg_dequeue to avoid crashing.

Title
drm/xe: Don't allow evicting of BOs in same VM in array of VM binds
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Don't allow evicting of BOs in same VM in array of VM binds
An array of VM binds can potentially evict other buffer objects (BOs)
within the same VM under certain conditions, which may lead to NULL
pointer dereferences later in the bind pipeline. To prevent this, clear
the allow_res_evict flag in the xe_bo_validate call.
v2:
- Invert polarity of no_res_evict (Thomas)
- Add comment in code explaining issue (Thomas)
(cherry picked from commit 8b9ba8d6d95fe75fed6b0480bb03da4b321bea08)

Title
ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_get_acpi_mute_state()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_get_acpi_mute_state()
Return value of a function acpi_evaluate_dsm() is dereferenced without
checking for NULL, but it is usually checked for this function.
acpi_evaluate_dsm() may return NULL, when acpi_evaluate_object() returns
acpi_status other than ACPI_SUCCESS, so add a check to prevent the crach.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Title
vfs: Don't leak disconnected dentries on umount
Summary
In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't leak disconnected dentries on umount
When user calls open_by_handle_at() on some inode that is not cached, we
will create disconnected dentry for it. If such dentry is a directory,
exportfs_decode_fh_raw() will then try to connect this dentry to the
dentry tree through reconnect_path(). It may happen for various reasons
(such as corrupted fs or race with rename) that the call to
lookup_one_unlocked() in reconnect_one() will fail to find the dentry we
are trying to reconnect and instead create a new dentry under the
parent. Now this dentry will not be marked as disconnected although the
parent still may well be disconnected (at least in case this
inconsistency happened because the fs is corrupted and .. doesn't point
to the real parent directory). This creates inconsistency in
disconnected flags but AFAICS it was mostly harmless. At least until
commit f1ee616214cb ("VFS: don't keep disconnected dentries on d_anon")
which removed adding of most disconnected dentries to sb->s_anon list.
Thus after this commit cleanup of disconnected dentries implicitely
relies on the fact that dput() will immediately reclaim such dentries.
However when some leaf dentry isn't marked as disconnected, as in the
scenario described above, the reclaim doesn't happen and the dentries
are "leaked". Memory reclaim can eventually reclaim them but otherwise
they stay in memory and if umount comes first, we hit infamous "Busy
inodes after unmount" bug. Make sure all dentries created under a
disconnected parent are marked as disconnected as well.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvfs: Don\u0027t leak disconnected dentries on umount\n\nWhen user calls open_by_handle_at() on some inode that is not cached, we\nwill create disconnected dentry for it. If such dentry is a directory,\nexportfs_decode_fh_raw() will then try to connect this dentry to the\ndentry tree through reconnect_path(). It may happen for various reasons\n(such as corrupted fs or race with rename) that the call to\nlookup_one_unlocked() in reconnect_one() will fail to find the dentry we\nare trying to reconnect and instead create a new dentry under the\nparent. Now this dentry will not be marked as disconnected although the\nparent still may well be disconnected (at least in case this\ninconsistency happened because the fs is corrupted and .. doesn\u0027t point\nto the real parent directory). This creates inconsistency in\ndisconnected flags but AFAICS it was mostly harmless. At least until\ncommit f1ee616214cb (\"VFS: don\u0027t keep disconnected dentries on d_anon\")\nwhich removed adding of most disconnected dentries to sb-\u003es_anon list.\nThus after this commit cleanup of disconnected dentries implicitely\nrelies on the fact that dput() will immediately reclaim such dentries.\nHowever when some leaf dentry isn\u0027t marked as disconnected, as in the\nscenario described above, the reclaim doesn\u0027t happen and the dentries\nare \"leaked\". Memory reclaim can eventually reclaim them but otherwise\nthey stay in memory and if umount comes first, we hit infamous \"Busy\ninodes after unmount\" bug. Make sure all dentries created under a\ndisconnected parent are marked as disconnected as well."

{
"lang": "en",
"value": "AV:L - The vulnerable path is entered through the `open_by_handle_at()` syscall (and the attacker must also drive the `umount` that converts the dentry leak into the busy-inode/superblock use-after-free), both of which require local system access. The nfsd file-handle path reaches the same code remotely but only produces the reclaimable leak, since a remote client cannot trigger the unmount.\nAC:L - With a malicious FUSE server (or a crafted/corrupt filesystem image, as in the syzbot reproducer) the attacker fully controls `get_parent()`, the readdir entry name, and the `lookup()` result, so the `tmp != dentry` mismatch in `reconnect_one()` is produced deterministically with no race to win. Even the alternate rename-race variant is driven by both sides under attacker control.\nPR:L - `may_decode_fh()` accepts `ns_capable(s_user_ns, CAP_SYS_ADMIN)` for `O_DIRECTORY` handles since v6.11, and FUSE is `FS_USERNS_MOUNT` with export ops enabled by a server-supplied flag, so an ordinary unprivileged user can satisfy every gate inside their own user namespace on their own mount. No real root in the initial namespace is needed.\nUI:N - The attacker performs the mount, the `open_by_handle_at()` call, and the unmount entirely themselves within their own user/mount namespace. No victim action is involved.\nS:U - The corruption is confined to kernel memory managed by the same kernel security authority; there is no VM, IOMMU, or hypervisor boundary crossed. This is standard in-kernel impact.\nC:H - The leaked dentries survive `generic_shutdown_super()` with `d_sb` pointing at a freed `super_block`, and the poisoned inodes remain on a torn-down superblock \u2014 a use-after-free that lets an attacker who sprays the freed slab read back kernel memory through subsequent dcache walks. Per UAF scoring this is High.\nI:H - The dangling `d_sb`/`d_op` and `list_lru_destroy()`d LRU heads mean later `__dentry_kill()`/`iput_final()` operate on reallocated memory, including indirect calls through `d_op-\u003ed_release`/`s_op` in a possibly unloaded module \u2014 a controllable write/control-flow primitive. Use-after-free is scored High for integrity.\nA:H - Unmount reliably produces the `VFS: Busy inodes after unmount` `CHECK_DATA_CORRUPTION` WARN \u2014 a `BUG()` with `CONFIG_BUG_ON_DATA_CORRUPTION` and an immediate panic with `panic_on_warn` \u2014 and the deliberately installed `VFS_PTR_POISON` guarantees a later oops when the leaked inodes are reclaimed."
