| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: avoid double drm_exec_fini() in userq validate
When new_addition is true, amdgpu_userq_vm_validate() calls
drm_exec_fini(&exec) before iterating over the collected HMM ranges and
calling amdgpu_ttm_tt_get_user_pages().
If amdgpu_ttm_tt_get_user_pages() fails in that path, the code jumps to
unlock_all and calls drm_exec_fini(&exec) a second time on the same
exec object. drm_exec_fini() is not idempotent: it frees exec->objects
and may also drop exec->contended and finalize the ww acquire context.
Route that error path directly to the range cleanup once exec has
already been finalized.
Issue found using a prototype static analysis tool
and confirmed by code review.

| In the Linux kernel, the following vulnerability has been resolved:
virt: sev-guest: Do not use host-controlled page order in cleanup path
When issuing an extended guest request (SVM_VMGEXIT_EXT_GUEST_REQUEST),
get_ext_report() allocates a buffer to retrieve a certificate blob from the
host, keeping track of its size in report_req->certs_len.
However, the host may return SNP_GUEST_VMM_ERR_INVALID_LEN, indicating
an invalid buffer size, as well as the expected length of such buffer.
get_ext_report() subsequently updates report_req->certs_len with the
host-controlled value, and cleans up the buffer by computing a page order
from such value. This is incorrect, as the host-provided length may not
match the page order of the original allocation, potentially resulting
in corruption in the page allocator.
Fix this by using alloc_pages_exact() instead, and reusing @npages to
compute the size passed to free_pages_exact(). For consistency, also
use @npages to compute the size when allocating the pages, even though
this last change has no functional effect. |
| In the Linux kernel, the following vulnerability has been resolved:
batman-adv: tvlv: reject oversized TVLV packets
batadv_tvlv_container_ogm_append() builds a TVLV packet section from
the tvlv.container_list. The total size of this section is computed by
batadv_tvlv_container_list_size(), which sums the sizes of all registered
containers.
The return type and accumulator in batadv_tvlv_container_list_size() were
u16. If the accumulated size exceeds U16_MAX, the value wraps around,
causing the subsequent allocation in batadv_tvlv_container_ogm_append()
to be undersized. The memcpy-style copy that follows would then write
beyond the end of the allocated buffer, corrupting kernel memory.
Fix this by widening the return type of batadv_tvlv_container_list_size()
to size_t. In batadv_tvlv_container_ogm_append(), check the computed length
against U16_MAX before proceeding, and bail out as if the allocation had
failed when the limit is exceeded. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: ipcomp: Free destination pages on acomp errors
Move the out_free_req label up by a couple of lines so that the
allocated dst SG list gets freed on error as well as success. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: scope conn->binding slowpath to bound sessions only
When the binding SESSION_SETUP sets conn->binding = true, the flag stays
set after the call so that the global session lookup in
ksmbd_session_lookup_all() can find the session, which was not added to
conn->sessions. Because the flag is connection-wide, the global lookup
path will also resolve any other session by id if asked.
Tighten the global lookup so that the returned session must have this
connection registered in its channel xarray (sess->ksmbd_chann_list).
The channel entry is installed by the existing binding_session path in
ntlm_authenticate()/krb5_authenticate() when a SESSION_SETUP completes
successfully, so this condition is a strict equivalent of "this
connection has been accepted as a channel of this session". Connections
that have not bound to a given session cannot reach it via the global
table.
The existing conn->binding gate for entering the slowpath is preserved
so that non-binding connections keep the fast-path-only behavior, and
the session->state check is unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: terminate the cached volume label after UTF-8 conversion
ntfs_fill_super() loads the on-disk volume label with utf16s_to_utf8s()
and stores the result in sbi->volume.label. The converted label is later
exposed through ntfs3_label_show() using %s, but utf16s_to_utf8s() only
returns the number of bytes written and does not add a trailing NUL.
If the converted label fills the entire fixed buffer,
ntfs3_label_show() can read past the end of sbi->volume.label while
looking for a terminator.
Terminate the cached label explicitly after a successful conversion and
clamp the exact-full case to the last byte of the buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: fix mismatch between power and frequency
During DPU runtime suspend, calling dev_pm_opp_set_rate(dev, 0) drops
the MMCX rail to MIN_SVS while the core clock frequency remains at its
original (highest) rate. When runtime resume re-enables the clock, this
may result in a mismatch between the rail voltage and the clock rate.
For example, in the DPU bind path, the sequence could be:
cpu0: dev_sync_state -> rpmhpd_sync_state
cpu1: dpu_kms_hw_init
timeline 0 ------------------------------------------------> t
After rpmhpd_sync_state, the voltage performance is no longer guaranteed
to stay at the highest level. During dpu_kms_hw_init, calling
dev_pm_opp_set_rate(dev, 0) drops the voltage, causing the MMCX rail to
fall to MIN_SVS while the core clock is still at its maximum frequency.
When the power is re-enabled, only the clock is enabled, leading to a
situation where the MMCX rail is at MIN_SVS but the core clock is at its
highest rate. In this state, the rail cannot sustain the clock rate,
which may cause instability or system crash.
Remove the call to dev_pm_opp_set_rate(dev, 0) from dpu_runtime_suspend
to ensure the correct vote is restored when DPU resumes.

ASoC: qcom: qdsp6: topology: check widget type before accessing data
Check widget type before accessing the private data, as this could a
virtual widget which is no associated with a dsp graph, container and
module. Accessing witout check could lead to incorrect memory access. |

| A flaw in Node.js TLS host verification can cause an attacker to bypass certification validation.
This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**. |
| Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.8.0, the Node.js compatibility TCP path checked the permission against the original hostname string before resolution and then did not re-check after resolution. A caller could therefore pass a numeric alias of an IP address (for example the decimal integer 2130706433 or the hex form 0x7f000001, both of which resolve to 127.0.0.1) and reach the denied destination through node:net.connect or node:http.request's { host, port } options form. This vulnerability is fixed in 2.8.0. |
| Missing SNI/ALPN binding on stateful (session-ID) resumption, which previously skipped the binding check performed for ticket-based resumption. A cached session could be resumed under a different SNI/ALPN than originally negotiated and, where client-authentication policy differs across virtual hosts, carry the cached peer-authentication state into a context it was not established for. Resumption now verifies the SNI/ALPN binding for all paths and declines (falling back to a full handshake) on mismatch. |
| TLS 1.3 post-handshake authentication (PHA) issue where a server could accept a client's Finished message without the client having sent a Certificate and CertificateVerify. The post-handshake-auth exemption that allows an empty/absent peer certificate was only intended for the initial handshake, but it was also being applied while a post-handshake CertificateRequest was still outstanding. The check is now scoped to the initial handshake only: on the server, once a post-handshake CertificateRequest has been sent (certReqCtx is set), a peer certificate and a valid CertificateVerify are required again before the Finished is accepted, with empty-certificate handling following the configured verify mode (FAIL_IF_NO_PEER_CERT) just as during first-handshake client authentication. Only affects TLS 1.3 servers built with post-handshake authentication support (WOLFSSL_POST_HANDSHAKE_AUTH / --enable-postauth, included in --enable-all) that enable WOLFSSL_VERIFY_POST_HANDSHAKE and request a client certificate after the handshake via wolfSSL_request_certificate(). Clients, and servers that do not use post-handshake authentication, are unaffected. |
| When Keycloak is started with `--features-disabled=account,account-api`, the Account REST API is only partially disabled. Five endpoints under the versioned path `/account/v1alpha1` remain fully functional — including both read and write operations — because they lack the `checkAccountApiEnabled()` gate that correctly blocks four other endpoints in the same REST service class. The user needs to have permissions to use the API. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: libertas: don't kill URBs in interrupt context
Serialization for the TX path was enforced by calling
usb_kill_urb()/usb_kill_anchored_urbs(), to prevent transmission before
a previous URB was completed. usb_tx_block() can be called from
interrupt context (e.g. in the HCD giveback path), so we can't always
use it to kill in-flight URBs.
Prevent sleeping during interrupt context by checking the tx_submitted
anchor for existing URBs. We now return -EBUSY, to indicate there's
a pending request. |

| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix abuse of kprobe_write_ctx via freplace
uprobe programs are allowed to modify struct pt_regs.
Since the actual program type of uprobe is KPROBE, it can be abused to
modify struct pt_regs via kprobe+freplace when the kprobe attaches to
kernel functions.
For example,
SEC("?kprobe")
int kprobe(struct pt_regs *regs)
{
return 0;
}
SEC("?freplace")
int freplace_kprobe(struct pt_regs *regs)
{
regs->di = 0;
return 0;
}
freplace_kprobe prog will attach to kprobe prog.
kprobe prog will attach to a kernel function.
Without this patch, when the kernel function runs, its first arg will
always be set as 0 via the freplace_kprobe prog.
To fix the abuse of kprobe_write_ctx=true via kprobe+freplace, disallow
attaching freplace programs on kprobe programs with different
kprobe_write_ctx values. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Switch CONFIG_CFI_CLANG to CONFIG_CFI
This was renamed in commit 23ef9d439769 ("kcfi: Rename CONFIG_CFI_CLANG
to CONFIG_CFI") as it is now a compiler-agnostic option. Using the wrong
name results in the code getting compiled out. Meaning the CFI failures
for btf_dtor_kfunc_t would still trigger. |
| In the Linux kernel, the following vulnerability has been resolved:
tun: zero the whole vnet header in tun_put_user()
tun_put_user() declares an on-stack struct virtio_net_hdr_v1_hash_tunnel
without zeroing it. For a non-tunnel skb, virtio_net_hdr_tnl_from_skb()
only initializes the first 10 bytes (sizeof(struct virtio_net_hdr)),
leaving bytes 10..23 (num_buffers and the hash/tunnel fields) as stack
garbage.
An unprivileged user can set the vnet header size to 24 with
TUNSETVNETHDRSZ, so __tun_vnet_hdr_put() copies all 24 bytes of the
partially-initialized struct to userspace, leaking 14 bytes of kernel
stack on every read of a non-tunnel packet.
Fix it the same way tun_get_user() already does by zeroing the whole
header right after declaration. |
