| Dell PowerProtect Data Manager, versions 20.2.0.0 and below, contain an Incorrect Authorization vulnerability in the REST API. A low privileged remote attacker could potentially exploit this vulnerability, leading to Protection mechanism bypass. |
| In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/amdgpu: fix aperture mapping leak"
devres teardown is LIFO. The aperture devres node was registered after
the DRM device node, so devres_release_all() unmaps the aperture before
the DRM device release callback fires amdgpu_device_fini_sw(). IP
sw_fini callbacks (e.g. vcn_v4_0_sw_fini) write to fw_shared through a
pointer derived from aper_base_kaddr, causing a kernel page fault on
probe failure / rollback:
BUG: unable to handle page fault ... PMD 0
RIP: vcn_v4_0_sw_fini+0x7b/0x170 [amdgpu]
Call Trace:

| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Fix crash passing ERR_PTR to kthread_stop()
In test_ringbuffer()'s out_free cleanup loop, the check
`!rb_threads[cpu]` only catches NULL entries and misses entries that
hold an ERR_PTR.
rb_threads[] is static, so unassigned slots are NULL. But when
kthread_run_on_cpu() fails for a cpu, it stores ERR_PTR(-ENOMEM) (or
-EINTR) in rb_threads[cpu] before the creation loop jumps to out_free.
That entry is non-NULL, so the old `!ptr` check does not break, and the
cleanup proceeds to call kthread_stop() on the ERR_PTR. kthread_stop()
then dereferences the bogus pointer, crashing the kernel during the
late_initcall self-test.

Kernel panic - not syncing: Fatal exception |
| In the Linux kernel, the following vulnerability has been resolved:
net: remove CAP_SYS_RAWIO zero-padding in dev_validate_header
dev_validate_header() reads dev->hard_header_len directly when
zero-padding short link layer headers for CAP_SYS_RAWIO holders:
if (capable(CAP_SYS_RAWIO)) {
memset(ll_header + len, 0, dev->hard_header_len - len);
return true;
}
Packet send paths call dev_validate_header() on skbs whose headroom was
allocated from an earlier hard_header_len read. If the device is
reconfigured so that dev->hard_header_len increases before validation,
the memset writes past the reserved buffer, an out-of-bounds write.
This out-of-bounds write is masked in some SOCK_RAW paths today because
the same concurrent increase can first make skb_push() exceed the
reserved headroom and trigger skb_under_panic(). Remove the zero-padding
branch before making those hard_header_len reads consistent, so the
snapshot fixes do not turn a loud panic into a silent overwrite.
This path is only reached for variable length L2 protocols, where
len < hard_header_len but len >= min_header_len. No remaining in-tree
variable length L2 protocol implements header_ops->validate, and the
CAP_SYS_RAWIO bypass that zero-pads and accepts short headers has no
real value beyond allowing testing of intentionally malformed input.
Drop the CAP_SYS_RAWIO branch. The remaining reads of
dev->hard_header_len in dev_validate_header() are comparisons only and
have no memory safety impact. |
| In the Linux kernel, the following vulnerability has been resolved:
net: remove WARN_ON_ONCE() from sk_mc_loop()
sk_mc_loop() can be called for sockets that are neither AF_INET
nor AF_INET6 (e.g. AF_PACKET sockets when sending packets via raw/packet
socket over virtual devices such as VRF or ipvlan).
In such cases, sk_family is not AF_INET/AF_INET6 and sk_mc_loop() falls
through the switch statement and triggers WARN_ON_ONCE(1).
Non-INET sockets do not support IP_MULTICAST_LOOP or IPV6_MULTICAST_LOOP
options, so loopback should default to true without generating a warning. |
| In the Linux kernel, the following vulnerability has been resolved:
af_packet: Don't send zero-byte data in tpacket_snd().
syzbot reported a WARNING in __dev_queue_xmit() triggered via tpacket_snd():
skb_assert_len
WARNING: at include/linux/skbuff.h:2753 skb_assert_len
WARNING: at __dev_queue_xmit+0x21bc/0x4970 net/core/dev.c:4781
Call Trace:
<TASK>

tpacket_snd net/packet/af_packet.c:2907 [inline]
packet_sendmsg+0x28d6/0x4eb0 net/packet/af_packet.c:3134
When sending 0-byte packets via TPACKET ring buffer on devices with no
hard header (e.g. dev->hard_header_len == 0), tpacket_fill_skb()
populates an skb with skb->len == 0 and returns 0. tpacket_snd() then
forwards this empty skb to packet_xmit(), causing __dev_queue_xmit() to
hit skb_assert_len(skb).
Similar checks exist in packet_snd() via commit dc633700f00f
("net/af_packet: check len when min_header_len equals to 0") and in
packet_sendmsg_spkt() via commit 6a341729fb31 ("af_packet: Don't send
zero-byte data in packet_sendmsg_spkt().").
Return -EINVAL in tpacket_fill_skb() when skb->len is zero to reject
zero-length packets in tpacket_snd(). |
| In the Linux kernel, the following vulnerability has been resolved:
pmdomain: mediatek: fix remaining %pOF after of_node_put()
scpsys_get_bus_protection_legacy() looks up several legacy bus
protection regmaps from device-tree nodes.
Two error paths put the device node before checking whether the regmap
lookup failed, but still pass that node to dev_err_probe() with %pOF on
failure. If of_node_put() drops the last reference, the later %pOF
formatting can dereference a freed device node.
Keep the node reference until after the error message has been emitted in
the infracfg and SMI lookup paths. Also drop the SMI node before
returning when the SMI phandle is missing. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: psxpad-spi - set driver data before use
psxpad_spi_suspend() retrieves the controller state with
spi_get_drvdata(), but probe never stores it, so suspend dereferences a
NULL pointer. Store it during probe. |
| A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation. |
| A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network access to the VNC WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client authentication. |
| In Stapler 2107.v8dfcb_e8ed317 and earlier, except 2088.2093.vd7c3e58008a_6, included in Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, form data binding allows setting public static fields of the bound configuration object, allowing attackers who can submit configuration forms to modify public static fields of the configuration objects those forms are bound to, resulting in changes that apply globally to the Jenkins instance. |
| Jenkins 2.579 and earlier, LTS 2.568.2 and earlier does not escape map keys when serializing objects as JSON and Python through its REST API, allowing attackers able to control map property names to inject arbitrary fields into JSON and Python API responses. |
| Incorrect Permission Assignment for Critical Resource (CWE-732) in Elastic Agent can lead to local privilege escalation via Replace Binaries (CAPEC-642). On Windows systems where Elastic Agent is installed in unprivileged mode, resources used by the agent service are created with access controls broader than required. A local user could take advantage of this to cause the service to execute code of their choosing, ultimately obtaining SYSTEM-level privileges on the host. |
| Incorrect Authorization (CWE-863) in the Kibana machine learning feature can lead to unauthorized resource consumption via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180). An authenticated user could invoke machine learning functionality beyond their authorization scope, consuming cluster resources they should not be able to reach. |
| An integer overflow vulnerability was found in gfs2-utils. The resource group allocation size computation on 32-bit platforms causes an undersized buffer allocation followed by heap out-of-bounds writes when processing crafted GFS2 filesystem images. This vulnerability does not affect 64-bit builds. |
| A vulnerability has been found in NousResearch hermes-agent 0.18.0. This affects the function fetchLinkTitle of the file apps/desktop/src/app/artifacts/index.tsx of the component Link Title Fetch. Such manipulation of the argument url leads to server-side request forgery. The attack can be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way. |
| A Pre-authentication SSRF vulnerability exists in the SMA1000 Appliance Work Place interface due to an unintended alternate access path. A remote unauthenticated attacker could potentially exploit this vulnerability to gain unauthorized access to sensitive functionality and perform unauthorized operations. |
| Vulnerability in Drupal Gammu SMS Daemon. This issue affects Gammu SMS Daemon versions: *.*. |
| A missing permission check in Jenkins 2.579 and earlier, LTS 2.568.2 and earlier allows attackers with Item/Read permission on at least one job to read build parameter names and values of jobs they have no access to. |
| In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the build CLI command does not check the Item/Cancel permission when using the -s flag to cancel a build triggered to wait for completion, allowing attackers with Item/Build permission to cancel builds started by other users. |
