ksmbd: fix signededness bug in smb_direct_prepare_negotiation()
smb_direct_prepare_negotiation() casts an unsigned __u32 value
from sp->max_recv_size and req->preferred_send_size to a signed
int before computing min_t(int, ...). A maliciously provided
preferred_send_size of 0x80000000 will return as smaller than
max_recv_size, and then be used to set the maximum allowed
alowed receive size for the next message.
By sending a second message with a large value (>1420 bytes)
the attacker can then achieve a heap buffer overflow.
This fix replaces min_t(int, ...) with min_t(u32) |
| In the Linux kernel, the following vulnerability has been resolved:
drm/ioc32: stop speculation on the drm_compat_ioctl path
The drm compat ioctl path takes a user controlled pointer, and then
dereferences it into a table of function pointers, the signature method
of spectre problems. Fix this up by calling array_index_nospec() on the
index to the function pointer list. |

drm/amd/display: Adjust PHY FSM transition to TX_EN-to-PLL_ON for TMDS on DCN35
[Why]
A backport of the change made for DCN401 that addresses an issue where
we turn off the PHY PLL when disabling TMDS output, which causes the
OTG to remain stuck.
The OTG being stuck can lead to a hang in the DCHVM's ability to ACK
invalidations when it thinks the HUBP is still on but it's not receiving
global sync.
The transition to PLL_ON needs to be atomic as there's no guarantee
that the thread isn't pre-empted or is able to complete before the
IOMMU watchdog times out.
[How]
Backport the implementation from dcn401 back to dcn35.
There's a functional difference in when the eDP output is disabled in
dcn401 code so we don't want to utilize it directly. |

netfilter: xt_tcpmss: check remaining length before reading optlen
Quoting reporter:
In net/netfilter/xt_tcpmss.c (lines 53-68), the TCP option parser reads
op[i+1] directly without validating the remaining option length.
If the last byte of the option field is not EOL/NOP (0/1), the code attempts
to index op[i+1]. In the case where i + 1 == optlen, this causes an
out-of-bounds read, accessing memory past the optlen boundary
(either reading beyond the stack buffer _opt or the
following payload). |
| In the Linux kernel, the following vulnerability has been resolved:
perf/x86: Fix potential bad container_of in intel_pmu_hw_config
Auto counter reload may have a group of events with software events
present within it. The software event PMU isn't the x86_hybrid_pmu and
a container_of operation in intel_pmu_set_acr_caused_constr (via the
hybrid helper) could cause out of bound memory reads. Avoid this by
guarding the call to intel_pmu_set_acr_caused_constr with an
is_x86_event check. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: caiaq: fix stack out-of-bounds read in init_card
The loop creates a whitespace-stripped copy of the card shortname
where `len < sizeof(card->id)` is used for the bounds check. Since
sizeof(card->id) is 16 and the local id buffer is also 16 bytes,
writing 16 non-space characters fills the entire buffer,
overwriting the terminating nullbyte.
When this non-null-terminated string is later passed to
snd_card_set_id() -> copy_valid_id_string(), the function scans
forward with `while (*nid && ...)` and reads past the end of the
stack buffer, reading the contents of the stack.
A USB device with a product name containing many non-ASCII, non-space
characters (e.g. multibyte UTF-8) will reliably trigger this as follows:
BUG: KASAN: stack-out-of-bounds in copy_valid_id_string
sound/core/init.c:696 [inline]
BUG: KASAN: stack-out-of-bounds in snd_card_set_id_no_lock+0x698/0x74c
sound/core/init.c:718
The off-by-one has been present since commit bafeee5b1f8d ("ALSA:
snd_usb_caiaq: give better shortname") from June 2009 (v2.6.31-rc1),
which first introduced this whitespace-stripping loop. The original
code never accounted for the null terminator when bounding the copy.
Fix this by changing the loop bound to `sizeof(card->id) - 1`,
ensuring at least one byte remains as the null terminator. |

| Due to not validating the organization context when executing adaptive authentication flows, the WSO2 Identity Server allows adaptive authentication logic to be triggered on unintended organizations. A malicious actor with privileges to configure adaptive authentication within one organization can leverage this functionality to execute authentication logic on other organizations and sub-organizations.
This flaw allows bypassing authorization boundaries between organizations, leading to unauthorized access to critical operations and user accounts in other organizations. When adaptive authentication is enabled in a multi-organization deployment, a malicious actor with privileges to configure adaptive authentication in one organization could exploit this feature to perform critical operations in other organizations without authorization. This may result in privilege escalation, unauthorized access to resources, and potential account takeover across organizations. |

| WWBN AVideo is an open source video platform. In versions up to and including 29.0, two endpoints (plugin/AI/receiveAsync.json.php and objects/EpgParser.php) in AVideo call isSSRFSafeURL() to validate user-supplied URLs, then fetch them using bare file_get_contents() without disabling PHP's automatic redirect following. An attacker can supply a URL pointing to a server they control that returns a 302 redirect to an internal/cloud-metadata address (e.g., http://169.254.169.254/latest/meta-data/). Since isSSRFSafeURL() only validates the initial URL, the redirect target bypasses all SSRF protections. Commit 603e7bf77a835584387327e35560262feb075db3 contains an updated fix. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: fix stack buffer overflow in hci_le_big_create_sync
hci_le_big_create_sync() uses DEFINE_FLEX to allocate a
struct hci_cp_le_big_create_sync on the stack with room for 0x11 (17)
BIS entries. However, conn->num_bis can hold up to HCI_MAX_ISO_BIS (31)
entries — validated against ISO_MAX_NUM_BIS (0x1f) in the caller
hci_conn_big_create_sync(). When conn->num_bis is between 18 and 31,
the memcpy that copies conn->bis into cp->bis writes up to 14 bytes
past the stack buffer, corrupting adjacent stack memory.
This is trivially reproducible: binding an ISO socket with
bc_num_bis = ISO_MAX_NUM_BIS (31) and calling listen() will
eventually trigger hci_le_big_create_sync() from the HCI command
sync worker, causing a KASAN-detectable stack-out-of-bounds write:
BUG: KASAN: stack-out-of-bounds in hci_le_big_create_sync+0x256/0x3b0
Write of size 31 at addr ffffc90000487b48 by task kworker/u9:0/71
Fix this by changing the DEFINE_FLEX count from the incorrect 0x11 to
HCI_MAX_ISO_BIS, which matches the maximum number of BIS entries that
conn->bis can actually carry. |
| WWBN AVideo is an open source video platform. In versions up to and including 29.0, plugin/PayPalYPT/agreementCancel.json.php cancels a PayPal billing agreement using an attacker-supplied agreement parameter without verifying that the authenticated user owns the agreement. A low-privilege authenticated user who learns or obtains another user's PayPal billing agreement ID can silently suspend the victim's recurring subscription, causing revenue loss to the platform and loss of paid service to the victim. Commit 0da3dcff1eda2f497694bf82b559829471c292c2 contains an updated fix. |
| WWBN AVideo is an open source video platform. In versions up to and including 29.0, the unauthenticated plugin/Scheduler/downloadICS.php endpoint passes attacker-controlled title, description, and joinURL parameters into Scheduler::downloadICS(), which builds an ICS calendar file via the ICS helper class. ICS::escape_string() (objects/ICS.php:167-169) only escapes , and ; and does NOT neutralize CR/LF, so attacker CRLF bytes inside a property value break out and inject arbitrary ICS lines — including END:VEVENT / BEGIN:VEVENT pairs that add entire attacker-controlled calendar events. Because the malicious .ics file is served from the victim's trusted AVideo origin, this enables high-credibility calendar phishing: forged meetings with attacker-chosen SUMMARY, URL, LOCATION, and DESCRIPTION landing in the victim's calendar after import. Commit 764db592f99e545aa86bb9a4ad664ffd14c38ba5 contains an updated fix. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: delete attr leaf freemap entries when empty
Back in commit 2a2b5932db6758 ("xfs: fix attr leaf header freemap.size
underflow"), Brian Foster observed that it's possible for a small
freemap at the end of the end of the xattr entries array to experience
a size underflow when subtracting the space consumed by an expansion of
the entries array. There are only three freemap entries, which means
that it is not a complete index of all free space in the leaf block.
This code can leave behind a zero-length freemap entry with a nonzero
base. Subsequent setxattr operations can increase the base up to the
point that it overlaps with another freemap entry. This isn't in and of
itself a problem because the code in _leaf_add that finds free space
ignores any freemap entry with zero size.
However, there's another bug in the freemap update code in _leaf_add,
which is that it fails to update a freemap entry that begins midway
through the xattr entry that was just appended to the array. That can
result in the freemap containing two entries with the same base but
different sizes (0 for the "pushed-up" entry, nonzero for the entry
that's actually tracking free space). A subsequent _leaf_add can then
allocate xattr namevalue entries on top of the entries array, leading to
data loss. But fixing that is for later.
For now, eliminate the possibility of confusion by zeroing out the base
of any freemap entry that has zero size. Because the freemap is not
intended to be a complete index of free space, a subsequent failure to
find any free space for a new xattr will trigger block compaction, which
regenerates the freemap.
It looks like this bug has been in the codebase for quite a long time. |

Bluetooth: SMP: derive legacy responder STK authentication from MITM state
The legacy responder path in smp_random() currently labels the stored
STK as authenticated whenever pending_sec_level is BT_SECURITY_HIGH.
That reflects what the local service requested, not what the pairing
flow actually achieved.
For Just Works/Confirm legacy pairing, SMP_FLAG_MITM_AUTH stays clear
and the resulting STK should remain unauthenticated even if the local
side requested HIGH security. Use the established MITM state when
storing the responder STK so the key metadata matches the pairing result.
This also keeps the legacy path aligned with the Secure Connections code,
which already treats JUST_WORKS/JUST_CFM as unauthenticated. |
