Title
sctp: prevent possible shift-out-of-bounds in sctp_transport_update_rto
Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: prevent possible shift-out-of-bounds in sctp_transport_update_rto
syzbot reported a possible shift-out-of-bounds [1]
Blamed commit added rto_alpha_max and rto_beta_max set to 1000.
It is unclear if some sctp users are setting very large rto_alpha
and/or rto_beta.
In order to prevent user regression, perform the test at run time.
Also add READ_ONCE() annotations as sysctl values can change under us.

Title
Bluetooth: 6lowpan: reset link-local header on ipv6 recv path
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: 6lowpan: reset link-local header on ipv6 recv path
Bluetooth 6lowpan.c netdev has header_ops, so it must set link-local
header for RX skb, otherwise things crash, eg. with AF_PACKET SOCK_RAW
Add missing skb_reset_mac_header() for uncompressed ipv6 RX path.
For the compressed one, it is done in lowpan_header_decompress().
Log: (BlueZ 6lowpan-tester Client Recv Raw - Success)

Title
Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF
There is a KASAN: slab-use-after-free read in btusb_disconnect().
Calling "usb_driver_release_interface(&btusb_driver, data->intf)" will
free the btusb data associated with the interface. The same data is
then used later in the function, hence the UAF.
Fix by moving the accesses to btusb data to before the data is free'd.
Severity
7.8 (High)

Title
Bluetooth: MGMT: cancel mesh send timer when hdev removed
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: cancel mesh send timer when hdev removed
mesh_send_done timer is not canceled when hdev is removed, which causes
crash if the timer triggers after hdev is gone.
Cancel the timer when MGMT removes the hdev, like other MGMT timers.
Should fix the BUG: sporadically seen by BlueZ test bot
(in "Mesh - Send cancel - 1" test).

Failed attempts are harmless and can be retried indefinitely.\nPR:N - smb2_check_user_session() explicitly bypasses session validation for SMB2_SESSION_SETUP, and the session is registered in conn-\u003esessions before any credential check, so the leaking lookup is reached with zero credentials. On the common guest-mapped ksmbd share, ntlm_authenticate() skips password verification for user_guest(), so the LOGOFF that flips the connection to NEED_RECONNECT is also available unauthenticated.\nUI:N - The attacker opens its own connections and issues every request itself; no legitimate user or administrator action is involved.\nS:U - The leaked session object and its pinned file references are kernel resources within the same security authority as the ksmbd server; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - Nothing is read out of bounds and nothing is transmitted back to the client on this error path \u2014 the only effect is that a reference count is never decremented, so no kernel data is disclosed.\nI:N - No memory is written out of bounds or freed early; the object simply outlives its intended lifetime, so no kernel data or control flow is modified.\nA:H - Each won race permanently leaks a struct ksmbd_session plus its entire file table, so open struct file/inode/dentry references are pinned forever (also blocking unmount), and the attack is replayable without limit over surviving connections, driving unbounded kernel memory and handle exhaustion to OOM and system hang."

Title
drm/amdgpu: Fix NULL pointer dereference in VRAM logic for APU devices
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix NULL pointer dereference in VRAM logic for APU devices
Previously, APU platforms (and other scenarios with uninitialized VRAM managers)
triggered a NULL pointer dereference in `ttm_resource_manager_usage()`. The root
cause is not that the `struct ttm_resource_manager *man` pointer itself is NULL,
but that `man->bdev` (the backing device pointer within the manager) remains
uninitialized (NULL) on APUs—since APUs lack dedicated VRAM and do not fully
set up VRAM manager structures. When `ttm_resource_manager_usage()` attempts to
acquire `man->bdev->lru_lock`, it dereferences the NULL `man->bdev`, leading to
a kernel OOPS.
1. **amdgpu_cs.c**: Extend the existing bandwidth control check in
`amdgpu_cs_get_threshold_for_moves()` to include a check for
`ttm_resource_manager_used()`. If the manager is not used (uninitialized
`bdev`), return 0 for migration thresholds immediately—skipping VRAM-specific
logic that would trigger the NULL dereference.
2. **amdgpu_kms.c**: Update the `AMDGPU_INFO_VRAM_USAGE` ioctl and memory info
reporting to use a conditional: if the manager is used, return the real VRAM
usage; otherwise, return 0. This avoids accessing `man->bdev` when it is
NULL.
3. **amdgpu_virt.c**: Modify the vf2pf (virtual function to physical function)
data write path. Use `ttm_resource_manager_used()` to check validity: if the
manager is usable, calculate `fb_usage` from VRAM usage; otherwise, set
`fb_usage` to 0 (APUs have no discrete framebuffer to report).
This approach is more robust than APU-specific checks because it:
- Works for all scenarios where the VRAM manager is uninitialized (not just APUs),
- Aligns with TTM's design by using its native helper function,
- Preserves correct behavior for discrete GPUs (which have fully initialized
`man->bdev` and pass the `ttm_resource_manager_used()` check).
v4: use ttm_resource_manager_used(&adev->mman.vram_mgr.manager) instead of checking the adev->gmc.is_app_apu flag (Christian)

Title
virtio-net: fix received length check in big packets
Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-net: fix received length check in big packets
Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length
for big packets"), when guest gso is off, the allocated size for big
packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends on
negotiated MTU. The number of allocated frags for big packets is stored
in vi->big_packets_num_skbfrags.
Because the host announced buffer length can be malicious (e.g. the host
vhost_net driver's get_rx_bufs is modified to announce incorrect
length), we need a check in virtio_net receive path. Currently, the
check is not adapted to the new change which can lead to NULL page
pointer dereference in the below while loop when receiving length that
is larger than the allocated one.
This commit fixes the received length check corresponding to the new
change.

This matches the CNA\u0027s treatment of comparable malicious-virtio-device bugs (CVE-2026-64456, CVE-2026-64490, CVE-2026-46123).\nAC:L - The same backend that announces the bogus length also controls feature negotiation and the advertised MTU, so it can deterministically create the vulnerable configuration (no MRG_RXBUF, no guest GSO, MTU \u003e 1500) and then announce any length up to MAX_SKB_FRAGS * PAGE_SIZE. No race, no memory-layout luck, and it can be repeated on every received packet.\nPR:N - The attacker acts from outside the guest\u0027s privilege model entirely \u2014 a compromised host/vhost_net or hostile virtio device holds no guest credentials and needs none, and the RX path runs unconditionally once the interface is up. Consistent with PR:N on the analogous virtio device-to-guest CVEs.\nUI:N - The corrupted length is consumed automatically in the NAPI receive path as soon as the backend completes a buffer; no guest user action is needed beyond the NIC being up.\nS:U - The vulnerable component and the impacted component are both the guest kernel \u2014 memory corruption stays within the guest\u0027s virtio-net driver and skb allocations. No IOMMU, VM, or sandbox boundary is crossed by the impact itself.\nC:H - An inflated length builds an skb whose fragments cover recycled driver pages that were never written by the device, disclosing stale kernel page contents (prior packet data) up the RX stack to guest userspace or back onto the wire, and the out-of-bounds frag-array write is memory corruption leverageable for further disclosure.\nI:H - With a backend-advertised MTU \u2265 61441, `big_packets_num_skbfrags` reaches 16 and the loop writes `skb_shinfo(skb)-\u003efrags[17]`, an out-of-bounds write of an attacker-influenced frag descriptor (size field) past the fixed `frags[MAX_SKB_FRAGS]` array into adjacent heap memory, plus corruption of `nr_frags`/`skb-\u003elen` \u2014 exactly the OOB write called out in the follow-up fix e6b8463b7d79.\nA:H - Once the page chain is exhausted, `skb_add_rx_frag()` dereferences a NULL `struct page` (`compound_head`/`page_is_pfmemalloc`) and the loop then reads `NULL-\u003eprivate`, causing a guest kernel oops in softirq context; it is trivially repeatable on every packet."

Title
iommufd: Don't overflow during division for dirty tracking
Summary
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Don't overflow during division for dirty tracking
If pgshift is 63 then BITS_PER_TYPE(*bitmap->bitmap) * pgsize will overflow
to 0 and this triggers divide by 0.
In this case the index should just be 0, so reorganize things to divide
by shift and avoid hitting any overflows.
Severity
No CVSS data available.

Title
Bluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()
In the parse_adv_monitor_pattern() function, the value of
the 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).
The size of the 'value' array in the mgmt_adv_pattern structure is 31.
If the value of 'pattern[i].length' is set in the user space
and exceeds 31, the 'patterns[i].value' array can be accessed
out of bound when copied.
Increasing the size of the 'value' array in
the 'mgmt_adv_pattern' structure will break the userspace.
Considering this, and to avoid OOB access revert the limits for 'offset'
and 'length' back to the value of HCI_MAX_AD_LENGTH.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.
