CVSS v3.1 |
| A cached crafted response can cause an out-of-bounds read if custom Lua code calls getDomainListByAddress() or getAddressListByDomain() on a packet cache. |
| A client can trigger excessive memory allocation by generating a lot of errors responses over a single DoQ and DoH3 connection, as some resources were not properly released until the end of the connection. |
| A client can trigger a divide by zero error leading to crash by sending a crafted DNSCrypt query. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: prevent policy_hthresh.work from racing with netns teardown
A XFRM_MSG_NEWSPDINFO request can queue the per-net work item
policy_hthresh.work onto the system workqueue.
The queued callback, xfrm_hash_rebuild(), retrieves the enclosing
struct net via container_of(). If the net namespace is torn down
before that work runs, the associated struct net may already have
been freed, and xfrm_hash_rebuild() may then dereference stale memory.
xfrm_policy_fini() already flushes policy_hash_work during teardown,
but it does not synchronize policy_hthresh.work.
Synchronize policy_hthresh.work in xfrm_policy_fini() as well, so the
queued work cannot outlive the net namespace teardown and access a
freed struct net. |

xfrm: iptfs: fix skb_put() panic on non-linear skb during reassembly
In iptfs_reassem_cont(), IP-TFS attempts to append data to the new inner
packet 'newskb' that is being reassembled. First a zero-copy approach is
tried if it succeeds then newskb becomes non-linear.
When a subsequent fragment in the same datagram does not meet the
fast-path conditions, a memory copy is performed. It calls skb_put() to
append the data and as newskb is non-linear it triggers
SKB_LINEAR_ASSERT check.
Oops: invalid opcode: 0000 [#1] SMP NOPTI

<TASK>
Fix this by checking if the skb is non-linear. If it is, linearize it by
calling skb_linearize(). As the initial allocation of newskb originally
reserved enough tailroom for the entire reassembled packet we do not
need to check if we have enough tailroom or extend it. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix undefined behavior in interpreter sdiv/smod for INT_MIN
The BPF interpreter's signed 32-bit division and modulo handlers use
the kernel abs() macro on s32 operands. The abs() macro documentation
(include/linux/math.h) explicitly states the result is undefined when
the input is the type minimum. When DST contains S32_MIN (0x80000000),
abs((s32)DST) triggers undefined behavior and returns S32_MIN unchanged
on arm64/x86. This value is then sign-extended to u64 as
0xFFFFFFFF80000000, causing do_div() to compute the wrong result.
The verifier's abstract interpretation (scalar32_min_max_sdiv) computes
the mathematically correct result for range tracking, creating a
verifier/interpreter mismatch that can be exploited for out-of-bounds
map value access.
Introduce abs_s32() which handles S32_MIN correctly by casting to u32
before negating, avoiding signed overflow entirely. Replace all 8
abs((s32)...) call sites in the interpreter's sdiv32/smod32 handlers.
s32 is the only affected case -- the s64 division/modulo handlers do
not use abs(). |
| In the Linux kernel, the following vulnerability has been resolved:
perf: Make sure to use pmu_ctx->pmu for groups
Oliver reported that x86_pmu_del() ended up doing an out-of-bound memory access
when group_sched_in() fails and needs to roll back.
This *should* be handled by the transaction callbacks, but he found that when
the group leader is a software event, the transaction handlers of the wrong PMU
are used. Despite the move_group case in perf_event_open() and group_sched_in()
using pmu_ctx->pmu.
Turns out, inherit uses event->pmu to clone the events, effectively undoing the
move_group case for all inherited contexts. Fix this by also making inherit use
pmu_ctx->pmu, ensuring all inherited counters end up in the same pmu context.
Similarly, __perf_event_read() should use equally use pmu_ctx->pmu for the
group case. |
| In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Fix leakage in __construct_region()
Failing the first sysfs_update_group() needs to explicitly
kfree the resource as it is too early for cxl_region_iomem_release()
to do so. |
| An attacker can send a notify request that causes a new secondary domain to be added to the bind backend, but causes said backend to update its configuration to an invalid one, leading to the backend no longer able to run on the next restart, requiring manual operation to fix it. |
| Incomplete escaping of LDAP queries when running with 8bit-dns enabled allows users to perform queries of internal domain subtrees. |
| Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, the GET /api/website/title endpoint accepts an arbitrary URL via the website_url query parameter and makes a server-side HTTP request to it without any validation of the target host or IP address. The endpoint requires no authentication. An attacker can use this to reach internal network services, cloud metadata endpoints (169.254.169.254), and localhost-bound services, with partial response data exfiltrated via the HTML <title> tag extraction This vulnerability is fixed in 4.2.8. |
| Out-of-bounds read in Windows Extensible File Allocation allows an authorized attacker to elevate privileges locally. |
| The MxChat – AI Chatbot for WordPress plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.5.5 via upload filenames. This makes it possible for unauthenticated attackers to extract session values that can subsequently be used to access conversation data. |
| Use after free in Windows Hyper-V allows an authorized attacker to elevate privileges locally. |
| Deserialization of untrusted data in Windows System Image Manager allows an authorized attacker to execute code locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Device Association Service allows an authorized attacker to elevate privileges locally. |
| A improper limitation of a pathname to a restricted directory ('path traversal') vulnerability in Fortinet FortiSandbox 5.0.0 through 5.0.5, FortiSandbox 4.4.0 through 4.4.8, FortiSandbox 4.2 all versions, FortiSandbox Cloud 5.0.4, FortiSandbox PaaS 5.0.4 may allow a privileged attacker with super-admin profile and CLI access to delete an arbitrary directory via HTTP crafted requests. |
| Incorrect permission assignment for critical resource in Windows Accessibility Infrastructure (ATBroker.exe) allows an authorized attacker to elevate privileges locally. |
| HTML injection is possible in system generated emails in Fortra's GoAnywhere MFT prior to 7.10.0.
Note: The title, details, and description of this CVE were corrected post-publishing. |
| External control of file name or path in Windows Kernel allows an authorized attacker to elevate privileges locally. |
