| NULL pointer dereference vulnerability in Samsung Open Source Walrus allows an attacker to cause a denial of service via a crafted WebAssembly module containing deeply nested instructions.
This issue affects Walrus: f339b8ee4ea701772e8ae640b3d1b12ac02b1ae9. |
| NULL pointer dereference vulnerability in Samsung Open Source Walrus allows Pointer Manipulation.
This issue affects Walrus: f339b8ee4ea701772e8ae640b3d1b12ac02b1ae9. |
| MapServer is a system for developing web-based GIS applications. From 6.4.0 to before 8.6.3, msSLDParseUserStyle always calls _SLDApplyRuleValues(psRule, psLayer, 1); for any <Rule> carrying <ElseFilter/> — it assumes msSLDParseRule added one class. When the rule has no symbolizer (a structurally valid SLD), msSLDParseRule adds zero, and _SLDApplyRuleValues ends up indexing _class[-1], resulting in a NULL pointer dereference. A 200-byte well-formed SLD via the WMS SLD_BODY= parameter is enough to trigger this, no auth required. This vulnerability is fixed in 8.6.3. |
| Memory Corruption when running a memory copy operation due to invalid writes caused by a null pointer. |
| A security flaw has been discovered in ggml-org whisper.cpp up to 1.8.2. This vulnerability affects the function whisper_model_load of the file ggml/src/ggml.c. The manipulation results in null pointer dereference. Attacking locally is a requirement. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet. |
| In libexpat before 2.7.4, XML_ExternalEntityParserCreate does not copy unknown encoding handler user data. |
| NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it can dereference a null pointer, which may lead to denial of service. |
| A segmentation violation in the gf_media_get_color_info function (/media_tools/isom_tools.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted data file. |
| A segmentation violation in the gf_isom_apple_set_tag_ex function (/isomedia/isom_write.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file. |
| A NULL pointer dereference in the gf_ac4_pres_b_4_back_channels_present function (/media_tools/av_parsers.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted AC4 file. |
| A NULL pointer dereference in the gf_odf_ac4_cfg_dsi_v1 function (/odf/descriptors.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted AC4 file. |
| ROHC protocol dissector crash in Wireshark 4.6.0 to 4.6.5 and 4.4.0 to 4.4.15 allows denial of service |
| cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.44.0, When the server has called Server::set_trusted_proxies() with a non-empty trusted-proxy list, an attacker can send an HTTP request that includes an X-Forwarded-For header whose value parses to no valid IP segments. The code path then executes get_client_ip(), which calls front() on an empty std::vector—undefined behavior in C++. On typical implementations this manifests as abnormal process termination (denial of service). With Sanitizers enabled, you get an explicit runtime diagnostic. This vulnerability is fixed in 0.44.0. |

| In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix NULL deref in ip_vs_add_service error path
When ip_vs_bind_scheduler() succeeds in ip_vs_add_service(), the local
variable sched is set to NULL. If ip_vs_start_estimator() subsequently
fails, the out_err cleanup calls ip_vs_unbind_scheduler(svc, sched)
with sched == NULL. ip_vs_unbind_scheduler() passes the cur_sched NULL
check (because svc->scheduler was set by the successful bind) but then
dereferences the NULL sched parameter at sched->done_service, causing a
kernel panic at offset 0x30 from NULL.
Oops: general protection fault, [..] [#1] PREEMPT SMP KASAN NOPTI
KASAN: null-ptr-deref in range [0x0000000000000030-0x0000000000000037]
RIP: 0010:ip_vs_unbind_scheduler (net/netfilter/ipvs/ip_vs_sched.c:69)

nf_setsockopt (net/netfilter/nf_sockopt.c:102)
[..]
Fix by simply not clearing the local sched variable after a successful
bind. ip_vs_unbind_scheduler() already detects whether a scheduler is
installed via svc->scheduler, and keeping sched non-NULL ensures the
error path passes the correct pointer to both ip_vs_unbind_scheduler()
and ip_vs_scheduler_put().
While the bug is older, the problem popups in more recent kernels (6.2),
when the new error path is taken after the ip_vs_start_estimator() call. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: xscale: Check for PTP support properly
In ixp4xx_get_ts_info() ixp46x_ptp_find() is called
unconditionally despite this feature only existing on
ixp46x, leading to the following splat from tcpdump:

Segmentation fault
Check for ixp46x in ixp46x_ptp_find() before trying to set up
PTP to avoid this.
To avoid altering the returned error code from ixp4xx_hwtstamp_set()
which before this patch was -EOPNOTSUPP, we return -EOPNOTSUPP
from ixp4xx_hwtstamp_set() if ixp46x_ptp_find() fails no matter
the error code. The helper function ixp46x_ptp_find() helper
returns -ENODEV. |
| free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's UDR nudr-dr DELETE /subscription-data/{ueId}/{servingPlmnId}/ee-subscriptions/{subsId}/amf-subscriptions handler contains a nil-pointer dereference reachable from a single authenticated request, after one preparatory authenticated EE-subscription create. The handler checks _, ok = UESubsData.EeSubscriptionCollection[subsId] and sets a 404 problem-details on the miss path, but then continues to UESubsData.EeSubscriptionCollection[subsId].AmfSubscriptionInfos -- dereferencing the same missing entry instead of returning. Gin recovery converts the panic into HTTP 500, but the endpoint remains repeatedly panicable. This vulnerability is fixed in 4.2.2. |
| In the Linux kernel, the following vulnerability has been resolved:
bareudp: fix NULL pointer dereference in bareudp_fill_metadata_dst()
bareudp_fill_metadata_dst() passes bareudp->sock to
udp_tunnel6_dst_lookup() in the IPv6 path without a NULL check.
The socket is only created in bareudp_open() and NULLed in
bareudp_stop(), so calling this function while the device is down
triggers a NULL dereference via sock->sk.
BUG: kernel NULL pointer dereference, address: 0000000000000018
