ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices
A bogus device can provide a bNumConfigurations value that exceeds the
initial value used in usb_get_configuration for allocating dev->config.
This can lead to out-of-bounds accesses later, e.g. in
usb_destroy_configuration.

No local access to the server is needed.\nAC:L - The attacker fully controls the precondition \u2014 a session with no backchannel connection is produced deterministically by creating a session without SESSION4_BACK_CHAN or by closing the connection that carried it, then poking the callback update path. No unpredictable memory layout or victim state is involved, and the sequence can be repeated at will.\nPR:N - EXCHANGE_ID/CREATE_SESSION/BIND_CONN_TO_SESSION are handled before any credential is actually verified, and the default SP4_NONE state protection makes nfsd4_mach_creds_match() a no-op; under AUTH_SYS/AUTH_NULL a client merely asserts an identity. Any host that can reach the exported NFS service can trigger it.\nUI:N - The whole sequence is issued by the attacking NFS client; no administrator or local user on the server has to mount anything, open a file, or take any action.\nS:U - The fault occurs in the nfsd callback workqueue inside the kernel\u0027s own security authority, and the damage is confined to that kernel instance. No VM, IOMMU, or sandbox boundary is crossed.\nC:N - The bug is a read of a NULL struct nfsd4_session pointer at a small fixed offset; it faults immediately rather than returning data, and no attacker-controlled memory is read back or exposed to the client.\nI:N - There is no write through the NULL pointer and no attacker-influenced offset \u2014 the assignments that follow never execute because the load faults first, so no kernel memory or file data can be modified.\nA:H - The dereference oopses in a workqueue kernel thread, killing the nfsd callback machinery and leaving locks/references stranded, which takes down NFS service and can panic the host on panic_on_oops systems. It is remotely and repeatably triggerable without authentication."

Title
af_packet: avoid erroring out after sock_init_data() in packet_create()
Summary
In the Linux kernel, the following vulnerability has been resolved:
af_packet: avoid erroring out after sock_init_data() in packet_create()
After sock_init_data() the allocated sk object is attached to the provided
sock object. On error, packet_create() frees the sk object leaving the
dangling pointer in the sock object on return. Some other code may try
to use this pointer and cause use-after-free.

Title
nvme-pci: fix freeing of the HMB descriptor table
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix freeing of the HMB descriptor table
The HMB descriptor table is sized to the maximum number of descriptors
that could be used for a given device, but __nvme_alloc_host_mem could
break out of the loop earlier on memory allocation failure and end up
using less descriptors than planned for, which leads to an incorrect
size passed to dma_free_coherent.
In practice this was not showing up because the number of descriptors
tends to be low and the dma coherent allocator always allocates and
frees at least a page.

Title
jffs2: Prevent rtime decompress memory corruption
Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: Prevent rtime decompress memory corruption
The rtime decompression routine does not fully check bounds during the
entirety of the decompression pass and can corrupt memory outside the
decompression buffer if the compressed data is corrupted. This adds the
required check to prevent this failure mode.

Title
KVM: Explicitly verify target vCPU is online in kvm_get_vcpu()
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Explicitly verify target vCPU is online in kvm_get_vcpu()
Explicitly verify the target vCPU is fully online _prior_ to clamping the
index in kvm_get_vcpu(). If the index is "bad", the nospec clamping will
generate '0', i.e. KVM will return vCPU0 instead of NULL.
In practice, the bug is unlikely to cause problems, as it will only come
into play if userspace or the guest is buggy or misbehaving, e.g. KVM may
send interrupts to vCPU0 instead of dropping them on the floor.
However, returning vCPU0 when it shouldn't exist per online_vcpus is
problematic now that KVM uses an xarray for the vCPUs array, as KVM needs
to insert into the xarray before publishing the vCPU to userspace (see
commit c5b077549136 ("KVM: Convert the kvm->vcpus array to a xarray")),
i.e. before vCPU creation is guaranteed to succeed.
As a result, incorrectly providing access to vCPU0 will trigger a
use-after-free if vCPU0 is dereferenced and kvm_vm_ioctl_create_vcpu()
bails out of vCPU creation due to an error and frees vCPU0. Commit
afb2acb2e3a3 ("KVM: Fix vcpu_array[0] races") papered over that issue, but
in doing so introduced an unsolvable teardown conundrum. Preventing
accesses to vCPU0 before it's fully online will allow reverting commit
afb2acb2e3a3, without re-introducing the vcpu_array[0] UAF race.

Title
sched: sch_cake: add bounds checks to host bulk flow fairness counts
Summary
In the Linux kernel, the following vulnerability has been resolved:
sched: sch_cake: add bounds checks to host bulk flow fairness counts
Even though we fixed a logic error in the commit cited below, syzbot
still managed to trigger an underflow of the per-host bulk flow
counters, leading to an out of bounds memory access.
To avoid any such logic errors causing out of bounds memory accesses,
this commit factors out all accesses to the per-host bulk flow counters
to a series of helpers that perform bounds-checking before any
increments and decrements. This also has the benefit of improving
readability by moving the conditional checks for the flow mode into
these helpers, instead of having them spread out throughout the
code (which was the cause of the original logic error).
As part of this change, the flow quantum calculation is consolidated
into a helper function, which means that the dithering applied to the
ost load scaling is now applied both in the DRR rotation and when a
sparse flow's quantum is first initiated. The only user-visible effect
of this is that the maximum packet size that can be sent while a flow
stays sparse will now vary with +/- one byte in some cases. This should
not make a noticeable difference in practice, and thus it's not worth
complicating the code to preserve the old behaviour.

Although cake also processes remotely-originated traffic on routers, the reliable and primary attack path is local, consistent with tc/qdisc classification.\nAC:L - The vulnerable host-fairness accounting is active in cake\u0027s default `triple-isolate` flow mode, and the attacker fully controls the packet 5-tuples used for the set-associative hash, so filling an 8-way set and forcing the mis-targeted decrement is deterministic and repeatable.\nPR:L - Qdisc installation is gated by `netlink_net_capable(skb, CAP_NET_ADMIN)`, which is evaluated against the netns user namespace, so any unprivileged user can obtain it with `unshare -Urn` and then attach cake to a loopback/veth device.\nUI:N - The attacker performs the qdisc setup and generates the triggering traffic entirely on their own; no action by any other user or administrator is needed.\nS:U - The out-of-bounds read and the counter corruption are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The u16 underflow makes `quantum_div[host_load]` read up to ~128 KB beyond a 1025-entry static array, and the value is folded into `flow-\u003edeficit`, which is exported via `TCA_CAKE_STATS_DEFICIT` \u2014 repeated samples defeat the random dithering and recover out-of-bounds kernel data, with the index steerable by additional spurious decrements.\nI:L - The bug persistently corrupts the per-host bulk-flow counters and injects out-of-bounds data into the scheduler\u0027s deficit state, modifying kernel data the attacker should not be able to touch, but there is no out-of-bounds write and no control over the written values.\nA:H - The wild index trips `WARN_ON(host_load \u003e CAKE_QUEUES)` (a panic under `panic_on_warn`) and reads far past the module\u0027s `.bss` into potentially unmapped vmalloc space, causing an oops; the qdisc state stays corrupted so the condition recurs on every dequeue."

Title
usb: cdc-acm: Check control transfer buffer size before access
Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: cdc-acm: Check control transfer buffer size before access
If the first fragment is shorter than struct usb_cdc_notification, we can't
calculate an expected_size. Log an error and discard the notification
instead of reading lengths from memory outside the received data, which can
lead to memory corruption when the expected_size decreases between
fragments, causing `expected_size - acm->nb_index` to wrap.
This issue has been present since the beginning of git history; however,
it only leads to memory corruption since commit ea2583529cd1
("cdc-acm: reassemble fragmented notifications").
A mitigating factor is that acm_ctrl_irq() can only execute after userspace
has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will
do that automatically depending on the USB device's vendor/product IDs and
its other interfaces.
Severity
No CVSS data available.
