Title
hwrng: ks-sa - fix division by zero in ks_sa_rng_init
Summary
In the Linux kernel, the following vulnerability has been resolved:
hwrng: ks-sa - fix division by zero in ks_sa_rng_init
Fix division by zero in ks_sa_rng_init caused by missing clock
pointer initialization. The clk_get_rate() call is performed on
an uninitialized clk pointer, resulting in division by zero when
calculating delay values.
Add clock initialization code before using the clock.

Title
dm: fix NULL pointer dereference in __dm_suspend()
Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: fix NULL pointer dereference in __dm_suspend()
There is a race condition between dm device suspend and table load that
can lead to null pointer dereference. The issue occurs when suspend is
invoked before table load completes:
BUG: kernel NULL pointer dereference, address: 0000000000000054
Oops: 0000 [#1] PREEMPT SMP PTI
CPU: 6 PID: 6798 Comm: dmsetup Not tainted 6.6.0-g7e52f5f0ca9b #62
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.1-2.fc37 04/01/2014
RIP: 0010:blk_mq_wait_quiesce_done+0x0/0x50
Call Trace:

The issue can be triggered as below:
T1 T2
dm_suspend table_load
__dm_suspend dm_setup_md_queue
dm_mq_init_request_queue
blk_mq_init_allocated_queue
=> q->mq_ops = set->ops; (1)
dm_stop_queue / dm_wait_for_completion
=> q->tag_set NULL pointer! (2)
=> q->tag_set = set; (3)
Fix this by checking if a valid table (map) exists before performing
request-based suspend and waiting for target I/O. When map is NULL,
skip these table-dependent suspend steps.
Even when map is NULL, no I/O can reach any target because there is
no table loaded; I/O submitted in this state will fail early in the
DM layer. Skipping the table-dependent suspend logic in this case
is safe and avoids NULL pointer dereferences.

Title
net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast
syzbot reported WARNING in rtl8150_start_xmit/usb_submit_urb.
This is the sequence of events that leads to the warning:
rtl8150_start_xmit() {
netif_stop_queue();
usb_submit_urb(dev->tx_urb);
}
rtl8150_set_multicast() {
netif_stop_queue();
netif_wake_queue(); <-- wakes up TX queue before URB is done
}
rtl8150_start_xmit() {
netif_stop_queue();
usb_submit_urb(dev->tx_urb); <-- double submission
}
rtl8150_set_multicast being the ndo_set_rx_mode callback should not be
calling netif_stop_queue and notif_start_queue as these handle
TX queue synchronization.
The net core function dev_set_rx_mode handles the synchronization
for rtl8150_set_multicast making it safe to remove these locks.

RAs are link-local and non-routable, so Adjacent rather than Network; the vector is the network stack, not the USB bus.\nAC:L - The attacker controls both sides of the race \u2014 they generate the TX load that guarantees an in-flight URB and drive rx_mode changes at an arbitrary rate \u2014 and the attempt is freely repeatable. The window between `urb-\u003ehcpriv = NULL` and `urb-\u003ecomplete()` in `__usb_hcd_giveback_urb()` is widened further by bulk giveback being deferred to a BH workqueue.\nPR:N - IPv6 Router Advertisement processing is unauthenticated by design and `accept_ra=1` is the default on non-forwarding hosts, so no credentials of any kind are needed on the adjacent path. Even the purely local path requires only an unprivileged `setsockopt(IP_ADD_MEMBERSHIP)` loop with no capabilities.\nUI:N - The kernel processes Router Advertisements and performs the resulting solicited-node multicast joins automatically in softirq on packet receive. No victim action is required at any point.\nS:U - The corruption is confined to kernel memory of the affected host, within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free leaves the HCD DMA-ing from a freed sk_buff data buffer and transmitting its contents onto the attacker\u0027s network segment, directly leaking reallocated kernel heap memory. Per guidance, a UAF also generically warrants C:H because it gives the attacker control over freed-object contents.\nI:H - The double free of an sk_buff corrupts the `skbuff_head_cache` slab freelist, a well-known heap-shaping and arbitrary-write primitive, and the still-queued URB writes/reads memory that can be reallocated to other kernel users mid-transfer.\nA:H - The reported `WARN_ONCE(\"URB submitted while active\")` is a kernel oops and a full panic under `panic_on_warn=1`, which is set in many hardened and production configurations. The UAF and double free crash the kernel outright, and the TX path is additionally left leaking sk_buffs."

Per CNA guidance Bluetooth-reachable code is Adjacent, and an attacker-controlled LE Audio device can drive the CIS/BIS setup and teardown events that complete the race.\nAC:L - The attacker controls both sides of the race directly \u2014 one thread calls `listen()` (which drops the socket lock across `iso_listen_bis()`, leaving `sk_state == BT_BOUND` while `conn-\u003esk` is set) while another calls `close()`, hitting the `default:` arm of `__iso_sock_close()` that zaps the socket without clearing `conn-\u003esk`. The window can be retried indefinitely, and the delayed conn put gives a long, tunable reallocation window.\nPR:L - `iso_sock_create()` performs no capability check, so any unprivileged local user can open a `BTPROTO_ISO` `SOCK_SEQPACKET` socket and drive the listen/close race; no CAP_NET_ADMIN or root is required.\nUI:N - The race is driven entirely by the attacker\u0027s own threads plus asynchronous HCI events; no action by a legitimate user or administrator is needed.\nS:U - The corruption is confined to kernel slab memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free on a freed `struct iso_pinfo` lets the attacker reoccupy the slab slot with a chosen object, and the stale `conn-\u003esk` plus the `iso_sock_hold()` read of freed memory can be leveraged into kernel memory disclosure.\nI:H - `iso_conn_free()` performs an 8-byte write at a fixed offset into the freed socket object; after heap spraying this becomes a targeted write into an attacker-chosen kernel structure, enabling pointer/refcount corruption and control-flow hijack.\nA:H - The use-after-free reliably corrupts slab memory and causes kernel oops/panic (as demonstrated by the KASAN slab-use-after-free report in the sibling SCO fix), and it can be triggered repeatedly."

mm: hugetlb: avoid soft lockup when mprotect to large memory area
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: hugetlb: avoid soft lockup when mprotect to large memory area
When calling mprotect() to a large hugetlb memory area in our customer's
workload (~300GB hugetlb memory), soft lockup was observed:

Soft lockup is not triggered with THP or base page because there is
cond_resched() called for each PMD size.
Although the soft lockup was triggered by MTE, it should be not MTE
specific. The other processing which takes long time in the loop may
trigger soft lockup too.
So add cond_resched() for hugetlb to avoid soft lockup.

No CVSS data available.

Title
ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping
Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping
When an invalid value is passed via quirk option, currently
bytcr_rt5640 driver only shows an error message but leaves as is.
This may lead to unepxected results like OOB access.
This patch corrects the input mapping to the certain default value if
an invalid value is passed.

Title
ext4: detect invalid INLINE_DATA + EXTENTS flag combination
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: detect invalid INLINE_DATA + EXTENTS flag combination
syzbot reported a BUG_ON in ext4_es_cache_extent() when opening a verity
file on a corrupted ext4 filesystem mounted without a journal.
The issue is that the filesystem has an inode with both the INLINE_DATA
and EXTENTS flags set:
EXT4-fs error (device loop0): ext4_cache_extents:545: inode #15:
comm syz.0.17: corrupted extent tree: lblk 0 < prev 66
Investigation revealed that the inode has both flags set:
DEBUG: inode 15 - flag=1, i_inline_off=164, has_inline=1, extents_flag=1
This is an invalid combination since an inode should have either:
- INLINE_DATA: data stored directly in the inode
- EXTENTS: data stored in extent-mapped blocks
Having both flags causes ext4_has_inline_data() to return true, skipping
extent tree validation in __ext4_iget(). The unvalidated out-of-order
extents then trigger a BUG_ON in ext4_es_cache_extent() due to integer
underflow when calculating hole sizes.
Fix this by detecting this invalid flag combination early in ext4_iget()
and rejecting the corrupted inode.

nvmet-fc: move lsop put work to nvmet_fc_ls_req_op
It’s possible for more than one async command to be in flight from
__nvmet_fc_send_ls_req. For each command, a tgtport reference is taken.
In the current code, only one put work item is queued at a time, which
results in a leaked reference.
To fix this, move the work item to the nvmet_fc_ls_req_op struct, which
already tracks all resources related to the command.

Consistent with other NVMe-oF target CVEs in this tree (including qla2xxx FC), the attacker is a remote peer on the storage fabric, which can itself be extended over routed transports.\nAC:L - The attacker controls both sides of the timing \u2014 issuing several associations and then disconnecting them concurrently reliably puts multiple LS requests in flight, and `queue_work()` deterministically drops every put after the first while one is pending. No memory-layout or victim-state condition is involved.\nPR:N - `nvmet_fc_ls_create_association()` and `nvmet_fc_ls_disconnect()` validate only LS descriptor lengths and tags; there is no host-NQN allow-list check, NVMe Connect, or authentication on this path. Any initiator that can reach the target port exercises it pre-authentication.\nUI:N - The leak is produced entirely by attacker-sent Link Service frames handled asynchronously by the target. No administrator or local user action is required.\nS:U - The leaked reference, stranded allocation, and failed teardown are all confined to the kernel of the target host. No security authority boundary such as a VM or IOMMU domain is crossed.\nC:N - The defect is purely a missed `kref_put()`; nothing is freed early, read out of bounds, or returned to the attacker. Tracing the coalescing shows it can only drop puts, never duplicate them, so no use-after-free read primitive exists.\nI:N - No memory is corrupted or written out of bounds \u2014 the refcount only ever ends too high, so no write or control-flow-hijack primitive arises. lpfc additionally guards its on-stack completion in `lpfc_nvmet_targetport_delete()`, closing the only late-completion write hazard.\nA:H - The tgtport is never freed, so `nvmet_fc_free_ls_iodlist()` and `targetport_delete` never run: `lpfc_nvmet_destroy_targetport()` stalls for `LPFC_NVMET_WAIT_TMO` (5 s) and then aborts with an error, permanently stranding the target port, its HBA DMA mappings, and a `get_device()` reference that no longer can be released without a reboot."

Title
net/ip6_tunnel: Prevent perpetual tunnel growth
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ip6_tunnel: Prevent perpetual tunnel growth
Similarly to ipv4 tunnel, ipv6 version updates dev->needed_headroom, too.
While ipv4 tunnel headroom adjustment growth was limited in
commit 5ae1e9922bbd ("net: ip_tunnel: prevent perpetual headroom growth"),
ipv6 tunnel yet increases the headroom without any ceiling.
Reflect ipv4 tunnel headroom adjustment limit on ipv6 version.
Credits to Francesco Ruggeri, who was originally debugging this issue
and wrote local Arista-specific patch and a reproducer.

{

"value": "AV:L - The unbounded growth is driven by the local transmit path (`ip6_tnl_xmit`) and requires the attacker to establish a two-tunnel routing loop and then push packets into it, which is done via netlink/socket operations on the local system. A purely remote attacker cannot create the required tunnel topology, so the reliable, fully attacker-controlled path is local.\nAC:L - The attacker controls every precondition \u2014 tunnel creation, the looping routes, and the packet stream \u2014 and each transmitted packet deterministically increments `dev-\u003eneeded_headroom` until the u16 header offset wraps; no race, memory-layout luck, or victim state is involved.\nPR:L - Configuring ip6tnl/ip6gre devices and routes needs CAP_NET_ADMIN, but an unprivileged user gains that in their own network namespace with `unshare -Urn`, and the resulting heap corruption is not confined to that namespace.\nUI:N - The attacker creates the tunnels and generates the traffic itself; no action by any other user or administrator is required.\nS:U - The corruption occurs in kernel memory within the same security authority; there is no VM, IOMMU, or hypervisor boundary crossed, making this standard in-kernel privilege escalation.\nC:H - Once `network_header` wraps, `skb-\u003edata` points outside `skb-\u003ehead`, producing out-of-bounds/use-after-free reads \u2014 the IPv4 twin of this bug was reported as a KASAN use-after-free read in `__skb_flow_dissect`, and such reads can disclose arbitrary adjacent kernel heap contents.\nI:H - After the negative `__skb_pull`, `dev_hard_header()` pushes and writes an L2 header at the out-of-bounds `skb-\u003edata`, giving an out-of-bounds write into unrelated kernel heap memory that can be leveraged for control-flow hijacking.\nA:H - The wrapped offsets and out-of-bounds accesses reliably produce kernel oops/panic, and the runaway headroom also forces ever-larger skb head reallocations, exhausting memory and destabilizing the system."
