ixgbe: do not configure xps for XDP queues
netif_set_xps_queue() should not be called for an XDP Tx queue, since such
queues are not netdev-exposed. On systems with number of CPUs >=64, on E610
adapter, netdev is configured with maximum number queue pairs being 63
(due to MSI-X assignment), but configuring XDP results in 64 XDP queues.
So, during XDP program load, when netif_set_xps_queue() is called for the
last XDP queue, we get a WARNING with a call trace and KASAN report
afterwards (if enabled).

| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local attacker to execute arbitrary code due to an out-of-bounds write. |
| Exposed methods allow authenticated users to create and execute arbitrary JavaScript code on the server. The scripts execute with full access, enabling complete system compromise as commands are executed as root. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix out-of-bounds clear_bit in ath12k_mac_dp_peer_cleanup()
ath12k_mac_dp_peer_cleanup() clears the ML peer ID slot on the
free_ml_peer_id_map bitmap by indexing it with dp_peer->peer_id. That is
wrong: dp_peer->peer_id for an MLO peer always carries the
ATH12K_PEER_ML_ID_VALID bit (BIT(13)), so clear_bit() is invoked with
index >= 0x2000, which is far outside the bitmap of ATH12K_MAX_MLO_PEERS
(256) bits and corrupts memory adjacent to ah->free_ml_peer_id_map. The
intended bitmap entry also never gets cleared, so subsequent
ath12k_peer_ml_alloc() calls eventually run out of IDs.
The ID without the VALID bit is what ath12k_peer_ml_alloc() returned and
is stored in ahsta->ml_peer_id. Use that instead.
While there, also reset ahsta->ml_peer_id to ATH12K_MLO_PEER_ID_INVALID so
the bitmap and ahsta->ml_peer_id stay in sync.

| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary code due to a buffer overflow. |
| IBM i 7.6, 7.5, 7.4, and 7.3 s vulnerable to a buffer overflow from improperly validating client data. By sending malformed requests to one of the host servers, a remote attacker could leverage this vulnerability to cause a denial-of-server (DoS) for that server. |
| In Roundcube Webmail before 1.6.18 and 1.7.x before 1.7.3, the cmd_learn driver of the markasjunk plugin is subject to remote code execution via crafted placeholder replacement values. This issue only affects Roundcube instances using the markasjunk plugin with its cmd_learn driver. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci: validate codec capability element length
Read Local Codec Capabilities returns a sequence of capability elements.
Each element starts with a one-byte length followed by that many payload
bytes.
hci_read_codec_capabilities() checks that the skb contains the length
byte, but then validates only caps->len against the remaining skb
length. A malformed controller response with one remaining byte and
caps->len set to one passes that check even though the element needs two
bytes. The parser then records a two-byte capability and copies one
byte beyond the advertised response payload into the codec list.
Validate the full element size, including the length byte, before adding
it to the accumulated capability length. This preserves all well-formed
capability elements and drops only truncated controller responses. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to execute arbitrary code due to a stack-based buffer overflow. |
| IBM i 7.6, 7.5, 7.4, and 7.3 is vulnerable to privilege escalation via Navigator for i. An authenticated user could elevate privileges to a root user to execute commands. |
| A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.
A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().
We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: fix OOB access from firmware tx status queue ID
ath_tx_edma_tasklet() accesses sc->tx.txq[ts.qid] where ts.qid is a
4-bit hardware field (0-15), but the txq array only has
ATH9K_NUM_TX_QUEUES (10) entries. A qid >= 10 causes an OOB array
access.
Add a bounds check on ts.qid before using it as an array index. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix KASAN slab-out-of-bounds in amdgpu_coredump ring dump
The ring content dump in amdgpu_coredump() uses two separate loops over
adev->rings[]: the first counts rings with unsignalled fences to size
the allocation, and the second copies ring data into the allocated
buffers.
Both loops use the same condition to skip rings:
atomic_read(&ring->fence_drv.last_seq) == ring->fence_drv.sync_seq
Because last_seq is an atomic that is updated concurrently by the fence
signalling path, additional rings may appear unsignalled in the second
loop that were signalled during the first. When this happens, idx
exceeds the allocated ring_count and the store to coredump->rings[idx]
writes past the end of the kcalloc-ed buffer.
This was found during IGT stressful test amd_queue_reset which
triggers random GPU resets. The OVERSIZE subtest
(CMD_STREAM_EXEC_INVALID_PACKET_LENGTH_OVERSIZE on GFX ring) provokes
a ring timeout and subsequent coredump, which hits the race between
the counting and copying loops. The failure is non-deterministic and
depends on fence signalling timing during the reset.

The buggy address belongs to the object at ffff888106154200
which belongs to the cache kmalloc-rnd-09-96 of size 96
The buggy address is located 16 bytes to the right of
allocated 72-byte region [ffff888106154200, ffff888106154248)
72 bytes = 3 * sizeof(struct amdgpu_coredump_ring), so ring_count was 3
but idx reached 3+, writing ring_index (at struct offset 16) 16 bytes
past the allocation.
Fix by adding an idx < ring_count guard to the copy loop so it cannot
exceed the allocated count even when the fence state changes between
the two passes. |

Fix this by accounting for the entry about to be written to, in addition to
the entries that are already allocated. |
| Nozomi Networks Labs identified a CWE-787: Out-of-bounds Write vulnerability in the process-image management functionality of KUNBUS piControl in version 2.6.2 that allows a local authenticated attacker with device configuration access to write attacker-controlled data outside the bounds of the process-image buffer and corrupt adjacent kernel memory, resulting in kernel memory corruption and denial of service, by supplying crafted device configuration data and crafted input through the piControl character device. |
| VP8L decoding in golang.org/x/image/vp8l can allocate an excessive amount of memory when processing a crafted VP8L image containing many unused Huffman tree groups. This allows a remote attacker to cause a denial of service via memory exhaustion. |
