CVSS v3.1 |
| A vulnerability exists in the interaction between a Endpoint Privilege Management (Windows Deployment) support utility and the agent's tamper protection controls. Under certain conditions, the protections applied to the utility process may not be enforced as intended. |
| A weakness has been identified in Open Asset Import Library Assimp 17c12da. The affected element is the function Assimp::MDLImporter::ReadFaces_3DGS_MDL7 in the library code/AssetLib/LWO/LWOLoader.h of the component 3DGS MDL7 Model Parser. Executing a manipulation can lead to heap-based buffer overflow. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. This patch is called ee77bb09a42a49843ac85ef64c14d2328b251df1. Applying a patch is advised to resolve this issue. |

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: reject undersized DACLs before parsing ACEs
parse_dacl() limits the attacker-controlled ACE count by comparing it
with the number of minimal ACEs that fit in the DACL size. The DACL size
field is 16 bits, but the expression subtracts sizeof(struct smb_acl).
Because sizeof() is unsigned, a DACL size smaller than the ACL header
underflows to a large size_t.
A malicious client can reach this with:
SMB2_SET_INFO (InfoType=SMB2_O_INFO_SECURITY)
-> smb2_set_info_sec()
-> set_info_sec()
-> parse_sec_desc()
-> parse_dacl()
-> init_acl_state(..., 0xffff)
-> init_acl_state(..., 0xffff)
-> kmalloc_objs(..., 0xffff)
Thus a malformed security descriptor can make num_aces pass the guard
and drive large temporary ACL state and pointer-array allocations.
Reject DACLs smaller than struct smb_acl before doing the subtraction,
so the ACE count check cannot be bypassed by the underflow. |

| In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix out-of-bounds access in nvme_setup_descriptor_pools
nvme_setup_descriptor_pools() indexes dev->descriptor_pools[] using the
numa_node forwarded from hctx->numa_node by its single caller,
nvme_init_hctx_common(). On a non-NUMA kernel hctx->numa_node is
NUMA_NO_NODE (-1). Because the parameter was declared 'unsigned', the
value becomes UINT_MAX and the index walks off the array (sized to
nr_node_ids), faulting during nvme_alloc_ns() and leaving the namespace
without a /dev node.
Reproduces on any NVMe controller probed by a CONFIG_NUMA=n kernel:
BUG: unable to handle page fault for address: ffff889101603d38
RIP: 0010:nvme_init_hctx_common+0x5a/0x190 [nvme]
Call Trace:
nvme_init_hctx+0x10/0x20 [nvme]
nvme_alloc_ns+0x9e/0xa10 [nvme_core]
nvme_scan_ns+0x301/0x3b0 [nvme_core]
nvme_scan_ns_async+0x23/0x30 [nvme_core]
Switch the parameter to int and fall back to node 0 when it is
NUMA_NO_NODE; node 0 is always present. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: fix wrong pci_get_drvdata type in AER handlers
rtw89 stores an ieee80211_hw pointer via pci_set_drvdata() at probe
time, but io_error_detected() and io_resume() retrieve it as a
net_device pointer. This causes netif_device_detach/attach to
operate on an ieee80211_hw struct, reading and writing at wrong
offsets. The adjacent io_slot_reset() already does it correctly.
Use ieee80211_stop_queues/wake_queues instead, consistent with
every other queue stop/start path in the driver.
Tested on RTL8852CE by calling the handlers from a test module
before and after the fix. |
| Improper isolation of shared resources within the CPU operation cache on Zen 2-based products could allow an attacker to corrupt instructions executed at a different privilege level, potentially resulting in privilege escalation. |
| In the Linux kernel, the following vulnerability has been resolved:
veth: convert frag_list skbs before running XDP
A frag_list skb can reach veth with data_len set but nr_frags zero.
veth_convert_skb_to_xdp_buff() only converts skbs that are shared,
locked, have frags[], or do not have enough headroom. It later uses
skb_is_nonlinear() to decide whether to set XDP_FLAGS_HAS_FRAGS and
xdp_frags_size.
That exposes frag_list data to XDP as if it were stored in frags[], but
frags[] is empty. AF_XDP copy mode can then trust the bogus XDP fragment
metadata, walk an empty fragment entry, and crash in memcpy() from
__xsk_rcv().
Route non-linear skbs through skb_pp_cow_data() before exposing them to
XDP, and only advertise XDP frags when the resulting skb has frags[].
skb_copy_bits() already handles frag_list input, and skb_pp_cow_data()
builds frags[] output with skb_add_rx_frag(), which is the
representation XDP multi-buffer expects. |
