CVSS v3.1 |
| json-smart through 2.6.0 contains an input validation bypass vulnerability that allows attackers to evade strict-mode trailing-data checks by inserting a literal 0x1A character. Attackers can append 0x1A and malformed content to pass JSONValue.parseStrict or isValidJsonStrict validation, creating parser differentials with downstream parsers like Jackson or Gson. |
| A service account with user-management permissions in one organization can read, modify, disable or delete users belonging to other organizations on the same Grafana instance through the SCIM API (insecure direct object reference). Only Grafana Enterprise instances with SCIM enabled are affected. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: fix WKS SAP hijacking via prefix match in nfc_llcp_wks_sap()
nfc_llcp_wks_sap() compares only service_name_len bytes, so a short
service_name like "u" matches longer WKS strings like "urn:nfc:sn:snep".
Fix by requiring exact length match before strncmp(). |
| In the Linux kernel, the following vulnerability has been resolved:
eth: fbnic: Avoid rounding zero ring sizes
roundup_pow_of_two() is undefined for zero. ethtool permits a zero ring
size to reach the driver, where the minimum-size check should reject it.
Leave zero unchanged while rounding nonzero ring sizes. The minimum-size
check then rejects zero deterministically without changing the established
behavior for other values. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Reject max_entries > INT_MAX in sock_map_alloc
sock_map_alloc() only rejects max_entries == 0 and otherwise allows any
u32 value. sock_map_free() then walks the sks[] array with a signed int
iterator:
int i;
for (i = 0; i < stab->map.max_entries; i++)
struct sock **psk = &stab->sks[i];
When a SOCKMAP is created with max_entries = 0xffffffff (UINT_MAX), the
allocation of 32 GiB can succeed on large-memory hosts. During free the
counter reaches 0x80000000, wraps to INT_MIN, is sign-extended by movslq
and turned into a ~16 GiB negative offset from stab->sks, pointing far
below the allocation.
The faulting access is an xchg() write in sock_map_free(). Without
KASAN, the same out-of-bounds write can fault on an unmapped vmalloc page
or corrupt an unrelated allocation if that vmalloc address is populated.
On a KASAN kernel with CONFIG_KASAN_VMALLOC=y, the shadow check for that
address hits an unmapped shadow page and oopses first:
BUG: unable to handle page fault for address: fffff521b59c5a00
RIP: 0010:kasan_check_range+0x107/0x190
Call Trace:
sock_map_free+0x93/0x190
map_create+0x68d/0xb30
__sys_bpf+0x21e/0x2e70
Vmcore confirmed stab->map.max_entries == 0xffffffff, stab->sks ==
0xffffc911ace2d000, and the faulting address sks + (s64)INT_MIN * 8
exactly at 0xffffc90dace2d000. The same buggy path is reached on the
normal close()/bpf_map_free_deferred() path whenever such a map is
destroyed.
sock_map_alloc() used to bound its allocation size through
bpf_map_charge_init(), but the bound was dropped when rlimit-based memory
accounting was removed. Reject max_entries > INT_MAX at creation time so
the signed iterator in sock_map_free() never sees a value that would
overflow.
Triggered by syzkaller and reproduced on both a 6.6-based KASAN kernel
and the upstream v7.3-rc2 kernel. |
| A stack overflow was addressed with improved input validation. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, visionOS 27. An attacker with a paired Bluetooth device may be able to execute arbitrary code. |
| Integer overflow or wraparound in Microsoft Office Outlook allows an unauthorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
af_packet: fix integer overflow in prb_calc_retire_blk_tmo()
prb_calc_retire_blk_tmo() computes in 32-bit int arithmetic:
mbits = (blk_size_in_bytes * 8) / (1024 * 1024);
If I'm reading the validation right, tp_block_size is user
controlled and packet_set_ring() only rejects values that are <= 0
as int or not page aligned, so a 256MiB block goes right through
(and alloc_one_pg_vec_page() even has a vzalloc fallback for it).
0x10000000 * 8 wraps to INT_MIN, and on a NIC reporting 1 Gbps
(div == 1) the function ends up returning -2047.
The condition is actually (8 * size) mod 2^32 >= 2^31 && div == 1,
so the trigger set is [256,512), [768,1024), [1280,1536) and
[1792,2048) MiB. Other sizes wrap to non-negative values and faster
links divide the unsigned value back below 2^31, which is why this
doesn't blow up for everyone.
What makes it fatal is what happens next in init_prb_bdqc():
p1->interval_ktime = ms_to_ktime(prb_calc_retire_blk_tmo(...));
hrtimer_start(&p1->retire_blk_timer, p1->interval_ktime,
HRTIMER_MODE_REL_SOFT);
A negative relative timeout expires immediately. The callback
unconditionally returns HRTIMER_RESTART, and hrtimer_forward() turns
the negative interval into hrtimer_resolution:
if (interval < hrtimer_resolution)
interval = hrtimer_resolution;
So the SOFT timer re-fires at the maximum rate forever, holding
sk_receive_queue.lock each pass. One CPU spins in softirq until the
socket is closed. Repeat with more rings and the machine is gone.
The overflow itself is ancient - it was introduced together with
TPACKET_V3 in f6fb8f100b80 ("af-packet: TPACKET_V3 flexible buffer
implementation."). Its effect prior to f7460d2989fa ("net:
af_packet: Use hrtimer to do the retire operation", v6.18) was not
as clear-cut, though: the return value was stored into an unsigned
short retire_blk_tov, so a negative result was truncated, and a
0-jiffy delay loop could be programmed as well. Neither is nearly
as detrimental as the immediate maximum-rate spin the hrtimer
conversion turned it into.
(Unrelated to CVE-2019-20812 - that one was the ethtool failure path
returning 0, which now returns DEFAULT_PRB_RETIRE_TOV.)
Reproducer, needs CAP_NET_RAW (a --network host container has it by
default) and a 1 Gbps NIC (QEMU e1000 works):
int fd = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
bind(fd, ...);
int v = TPACKET_V3;
setsockopt(fd, SOL_PACKET, PACKET_VERSION, &v, sizeof(v));
struct tpacket_req3 req = {
.tp_block_size = 0x10000000,
.tp_block_nr = 1,
.tp_frame_size = 2048,
.tp_frame_nr = 0x10000000 / 2048,
.tp_retire_blk_tov = 0,
};
setsockopt(fd, SOL_PACKET, PACKET_RX_RING, &req, sizeof(req));
Compute in 64 bits instead. The operands are already bounded by the
existing validation, so nothing else changes. If you'd prefer a
different fix, just say so and I'll respin. |
| In Progress® Kendo® UI for jQuery prior to 2026.3.1015, Model.accept passes server-response keys to kendo.setter without guarding against unsafe object paths containing __proto__, constructor, or prototype. An attacker who can supply data accepted by an affected model can modify object prototype attributes and influence application behavior, potentially compromising the confidentiality and integrity of application data. The impact depends on how the application uses the modified objects, including in server-side JavaScript scenarios. The earliest affected version has not been confirmed. This issue is fixed in version 2026.3.1015. |
| OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to 2.4.20, the cupsdCreateJob option-string builder in scheduler/job.c maps attacker-controlled destination-uri and pre-dial-string values from a configured fax queue to the phone and faxPrefix options. Unlike ordinary IPP job attributes, these mapped fax values bypass the control-character sanitizer and are copied directly into the filter options argument. A user permitted to submit a job can therefore inject control characters into the downstream option stream. The reporter states that a downstream fax filter passing these values to a shell or modem command could execute code as lp, while the maintainer states that CUPS has no confidentiality or integrity impact because the only known code-executing filter is optional Foomatic and addressed separately, leaving possible disruption of the affected queue. This issue is fixed in version 2.4.20. |
| Buffer under-read vulnerability in Apache Tomcat meant that a large non-blocking write could result in the response body being split between the current request and the next request received on that connection leading most likely to failure of the second request and possibly leakage of data from the first response to the second.
This issue affects Apache Tomcat: from 11.0.0-M25 through 11.0.26.
Users are recommended to upgrade to version 11.0.27, which fixes the issue. |
| Out-of-bounds read in DNS Server allows an authorized attacker to disclose information over a network. |
| Improper validation of pod identifier uniqueness in aws-network-policy-agent in Amazon EKS Network Policy Agent before v1.4.0 might allow an authenticated remote user to bypass NetworkPolicy enforcement on co-located pods in other namespaces via crafted pod and namespace names that produce pod identifier collisions.
To remediate this issue, users should upgrade to Amazon EKS Network Policy Agent 1.4.0 or later and Amazon VPC CNI Managed Add-on v1.22.4 or later (which includes Network Policy Agent v1.4.0). |
| Stirling-PDF from 2.13.2 through 3.2.0 contains an incomplete denylist in DatabaseService.validateSqlContent() that allows administrators to bypass H2 import restrictions using CREATE OR REPLACE ALIAS. Authenticated administrators can upload a crafted SQL backup to the import-database endpoint, where RUNSCRIPT defines H2 Java function aliases and restores Java-method execution. |
| Numeric truncation of the buffer length in the MPU buffer authorization check in FreeRTOS-Kernel V11.3.0 and V11.3.1 on the Arm Cortex-R82 (Armv8-R AArch64) MPU port might allow, under certain conditions, an unprivileged task on MPU-enabled builds to read or write privileged kernel memory beyond the validated buffer window, via a stream buffer system call.
To remediate this issue, users should upgrade to version V11.3.2 or later. |
| A vulnerability is in Web Server default connection ports under the process name GeoWebServer.exe . |
| A heap buffer overflow in the gf_odf_ac4_cfg_alternative_info function (/odf/descriptors.c) of GPAC Project/MP4Box 2.5-DEV-rev1593-gfe88c3545-master allows attackers to cause a Denial of Service (DoS) via supplying a crafted AC4 file. |
| A segmentation violation in the dump_isom_saps function (/mp4box/filedump.c) of GPAC MP4Box v2.5-DEV-rev1672-gc9a31d0e1-masterallows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file. |
| In the Linux kernel, the following vulnerability has been resolved:
net: skbuff: fix pull-bound underflow in skb_checksum_setup_ipv6()
skb_maybe_pull_tail() subtracts skb_headlen(skb) from the unsigned max
argument and passes the result to __pskb_pull_tail() as a signed int. The
function does not ensure that max is at least skb_headlen(skb).
This can happen while parsing IPv6 extension headers when an skb already
has a linear area larger than MAX_IPV6_HDR_LEN. Once the parser needs data
beyond the linear area, max - skb_headlen(skb) wraps and is converted to a
negative delta. __pskb_pull_tail() then passes that negative length to
skb_copy_bits(), where it can become a very large copy length.
Pass the requested length itself as the pull bound at the three
extension-header call sites, so the delta can no longer go negative. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: fix slab-out-of-bounds reads when logging service names
nfc_llcp_wks_sap() and nfc_llcp_build_sdreq_tlv() pass non-null-
terminated strings to pr_debug() using the %s format specifier.
The buffers are allocated via kmemdup() or come from netlink
attributes and are not guaranteed to be null-terminated, causing
__dynamic_pr_debug() to read beyond the allocated region:
KASAN: slab-out-of-bounds Read in __dynamic_pr_debug
Fix both call sites by using %.*s with the explicit length to limit
the output to the actual length of the string. |
