CVSS v3.1 |
| A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.
The security update addresses the vulnerability by modifying how the scripting engine handles objects in memory. |
| An elevation of privilege vulnerability exists when the Windows Runtime improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in an elevated context.
An attacker could exploit this vulnerability by running a specially crafted application on the victim system.
The update addresses the vulnerability by correcting the way the Windows Runtime handles objects in memory. |
| An elevation of privilege vulnerability exists when Windows Error Reporting manager improperly handles file and folder links. An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status.

| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix auth_chunk_list capacity check in sctp_auth_ep_add_chunkid
sctp_auth_ep_add_chunkid() uses SCTP_NUM_CHUNK_TYPES (20) as the
capacity limit for ep->auth_chunk_list, allowing it to hold up to
20 chunk entries (param_hdr.length up to 24). However, the copy
destination asoc->c.auth_chunks in struct sctp_cookie is only
SCTP_AUTH_MAX_CHUNKS (16) entries (20 bytes). When more than 16
chunks are added, sctp_association_init() memcpy overflows the
destination by up to 4 bytes.
Fix by using SCTP_AUTH_MAX_CHUNKS as the capacity limit, matching
the destination capacity. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: validate stream count in sctp_process_strreset_inreq()
When processing a RESET_IN_REQUEST from a peer,
sctp_process_strreset_inreq() derives the stream count from the
parameter length but does not check whether the resulting
RESET_OUT_REQUEST would exceed SCTP_MAX_CHUNK_LEN.
The OUT request header (sctp_strreset_outreq, 16 bytes) is 8 bytes
larger than the IN request header (sctp_strreset_inreq, 8 bytes).
Generally, the IP payload is bounded to 65535 bytes, so the stream
list cannot be large enough to trigger the overflow. However, on
interfaces with MTU > 65535 (e.g., loopback with IPv6 jumbograms), a
stream list that fits within the incoming IN parameter can cause a
__u16 overflow in sctp_make_strreset_req() when computing the OUT
request size, leading to an undersized skb allocation and a kernel
BUG:
net/core/skbuff.c:207 skb_panic
net/core/skbuff.c:2625 skb_put
net/sctp/sm_make_chunk.c:1535 sctp_addto_chunk
net/sctp/sm_make_chunk.c:3695 sctp_make_strreset_req
net/sctp/stream.c:655 sctp_process_strreset_inreq
The local setsockopt path validates the generated reset request size.
However, for an incoming-only reset, it accounts for the smaller IN
request even though the peer must generate an OUT request with the same
stream list. Such a request cannot be completed successfully by the
peer.
Reject peer IN requests whose corresponding OUT request would exceed
SCTP_MAX_CHUNK_LEN. Also tighten the local check so it does not send an
IN request that would require an oversized OUT request from the peer. |
| GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.1.4 and 19.2 before 19.2.2 that under certain conditions could have allowed an authenticated user to cause AI usage to be attributed to another namespace, due to improper authorization of identity information supplied in requests. |
| In the Linux kernel, the following vulnerability has been resolved:
vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets
vmxnet3_get_hdr_len() assumes gdesc->rcd.v4/v6/tcp always describe the
outer header, but for a Geneve-encapsulated packet the device can set
them based on the inner header instead, signalled by the
VMXNET3_RCD_HDR_INNER_SHIFT bit in the completion descriptor. Since the
function never skips the outer encapsulation, this mismatch triggers:
- BUG_ON(hdr.ipv4->protocol != IPPROTO_TCP), because the outer
protocol is UDP (Geneve), not TCP.
- BUG_ON(hdr.eth->h_proto != ...), when the tunnel's outer and inner
IP versions differ (e.g. outer IPv6/inner IPv4 or vice versa).
Check VMXNET3_RCD_HDR_INNER_SHIFT up front and bail out, since the
function cannot locate the inner header it would need to parse. Also
convert the remaining BUG_ON()s in this function to return 0
defensively. |
| In the Linux kernel, the following vulnerability has been resolved:
tipc: fix u16 MTU truncation in media and bearer MTU validation
Both TIPC_NL_MEDIA_SET and TIPC_NL_BEARER_SET accept user-supplied
MTU values but only enforce a minimum bound, not a maximum. When a user
sets the MTU to a value exceeding U16_MAX (65535), it passes validation
but is silently truncated when assigned to u16 fields l->mtu and
l->advertised_mtu in tipc_link_create(). Values like 65536 (0x10000)
truncate to 0, causing a division by zero in tipc_link_set_queue_limits()
which computes TIPC_MAX_PUBL / (l->mtu / ITEM_SIZE). Other overflowing
values (e.g. 65537-131071) produce small incorrect MTU values, resulting
in link malfunction behaviors.
Crash stack (triggered as unprivileged user via user namespace):
tipc_link_set_queue_limits net/tipc/link.c:2531
tipc_link_create net/tipc/link.c:520
tipc_node_check_dest net/tipc/node.c:1279
tipc_disc_rcv net/tipc/discover.c:252
tipc_rcv net/tipc/node.c:2129
tipc_udp_recv net/tipc/udp_media.c:392
Two independent paths lack the upper bound check:
1. tipc_udp_mtu_bad() -- called from __tipc_nl_media_set() (MEDIA_SET)
2. inline check in __tipc_nl_bearer_set() at bearer.c:1160 (BEARER_SET)
Fix both by rejecting MTU values above U16_MAX. |
| GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.1.4 and 19.2 before 19.2.2 that under certain conditions could have allowed an authenticated user to modify project settings restricted to higher-privileged roles, due to missing authorization checks on a project update endpoint. |
| In the Linux kernel, the following vulnerability has been resolved:
media: cedrus: skip invalid H.264 reference list entries
Cedrus consumes H.264 ref_pic_list0/ref_pic_list1 entries from the
stateless slice control and later uses their indices to look up
decode->dpb[] in _cedrus_write_ref_list().
Rejecting such controls in cedrus_try_ctrl() would break existing
userspace, since stateless H.264 reference lists may legitimately carry
out-of-range indices for missing references. Instead, guard the actual
DPB lookup in Cedrus and skip entries whose indices do not fit the fixed
V4L2_H264_NUM_DPB_ENTRIES array.
This keeps the fix local to the driver use site and avoids out-of-bounds
reads from malformed or unsupported reference list entries. |
| In the Linux kernel, the following vulnerability has been resolved:
media: msi2500: Return queued buffers on start_streaming() failure
The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming(). If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.
msi2500_start_streaming() had five error paths that all hit this trap
and were further tangled by ret-overwriting between calls:
- -ENODEV when the USB device was already disconnected
- -ERESTARTSYS when mutex_lock_interruptible() was interrupted
- msi2500_set_usb_adc() failure: ret was silently overwritten by
the next call (msi2500_isoc_init), so the error was lost entirely
- msi2500_isoc_init() failure: cleanup_queued_bufs was called, but
the function then fell through to msi2500_ctrl_msg() and again
masked the original error by overwriting ret
- msi2500_ctrl_msg(CMD_START_STREAMING) failure: no cleanup at all,
leaving isoc URBs submitted with no way for the driver to consume
them
Consolidate the error paths into a small goto chain. Every failure
now stops the function, drains the queued-buffer list, and returns
the real error code. The ctrl_msg failure path also rolls back the
preceding msi2500_isoc_init() via msi2500_isoc_cleanup() before
unlocking and draining.
The cleanup helper takes a vb2_buffer_state argument so that the
start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as
expected by userspace on start_streaming failure) while stop_streaming
keeps its existing VB2_BUF_STATE_ERROR semantics.
This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure"). |

media: rtl2832_sdr: Return queued buffers on start_streaming() failure
The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming(). If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.
rtl2832_sdr_start_streaming() had multiple error paths that hit this
trap: two direct early returns (-ENODEV, -ERESTARTSYS), plus six
`goto err` paths covering subdev s_power, tuner setup, ADC setup,
stream-buffer allocation, urb allocation, and urb submission failures.
None of them returned the queued buffers.
The original function had no distinct success exit and fell straight
through into the err label, which previously only did mutex_unlock and
"return ret". Adding queued-buffer cleanup at err must therefore be
paired with an explicit success return; otherwise every successful
start would also drain the buffer queue and kill streaming. Add that
success return, then add rtl2832_sdr_cleanup_queued_bufs() at the err
label and before each early return.
The cleanup helper takes a vb2_buffer_state argument so that the
start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as
expected by userspace on start_streaming failure) while stop_streaming
keeps its existing VB2_BUF_STATE_ERROR semantics.
This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure").
The err label still does not roll back power_ctrl(), frontend_ctrl(),
the POWER_ON flag, or stream/URB allocations that may have happened
before the failing step. Those are pre-existing leaks of a different
class and are not addressed here. |
