CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
net: enetc: check the number of BDs needed for xdp_frame
The size of xdp_redirect_arr array is ENETC_MAX_SKB_FRAGS. However, the
number of fragments contained in xdp_frame may be greater than or equal
to ENETC_MAX_SKB_FRAGS, which will cause the access to xdp_redirect_arr
to be out of bounds. |
| The Zephyr ADIN2111/ADIN1110 10BASE-T1S/T1L Ethernet driver (drivers/ethernet/eth_adin2111.c) reassembles received Ethernet frames in OPEN Alliance (OA) SPI mode by copying device-supplied 64-byte data chunks into a fixed static buffer ctx->buf of size CONFIG_ETH_ADIN2111_BUFFER_SIZE (default 1524 bytes). In eth_adin2111_oa_data_read(), each valid chunk was memcpy'd into ctx->buf[ctx->scur] and the write cursor scur advanced, with no check that scur + len stayed within the buffer. The number of chunks (up to 255, from the BUFSTS RCA field) and the per-chunk length are taken entirely from the frame data received off the wire; the cursor is only reset on a start-of-frame chunk. An attacker on the single-pair Ethernet segment can therefore send a frame whose reassembled size exceeds the configured buffer, causing the driver's RX offload thread to write attacker-controlled frame bytes past the end of the static buffer into adjacent driver/kernel memory (up to roughly 14.8 KB in the worst case). This is a remotely/adjacently reachable out-of-bounds write (CWE-787) that can corrupt memory and cause denial of service or potentially code execution. The defect was introduced when OA SPI support was added (commit 0ca8b0756b1) and shipped in releases v3.7.0 through v4.4.0. The fix adds a bounds check that drops the oversized frame and resets the cursor before the copy. |
| IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.5 is vulnerable to buffer overflow in the IXF IMPORT parser. |
| In the Linux kernel, the following vulnerability has been resolved:
cifs: validate DFS referral string offsets
parse_dfs_referrals() validates that the response header and referral
array fit in the received buffer, but each referral also contains string
offsets supplied by the server.
Those offsets are used to compute the DfsPath and NetworkAddress string
pointers without checking whether they still point inside the response
buffer. A malformed referral can therefore make the computed pointer
exceed the end of the buffer. The resulting negative max_len is then
passed to cifs_strndup_from_utf16(), and the non-Unicode path forwards it
to kstrndup() as a size_t, allowing strnlen() to read out of bounds.
Validate each string offset before deriving the string pointer. |

| In the Linux kernel, the following vulnerability has been resolved:
gue: validate REMCSUM private option length
GUE private flags can indicate that remote checksum offload metadata is
present. The private flags field itself is accounted for by
guehdr_flags_len(), but guehdr_priv_flags_len() currently returns 0 even
when GUE_PFLAG_REMCSUM is set.
This lets a packet with only the private flags field pass
validate_gue_flags(), after which gue_remcsum() and gue_gro_remcsum()
read the missing REMCSUM start/offset fields from the following bytes.
Account for GUE_PLEN_REMCSUM when GUE_PFLAG_REMCSUM is present so that
malformed packets are rejected during option validation. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: flowtable: fix and simplify IP6IP6 tunnel handling
Fix nf_flow_ip6_tunnel_proto() to use pskb_may_pull() instead of
skb_header_pointer() to ensure the outer IPv6 header is in the skb
headroom, which is required for subsequent packet processing. Move
ctx->offset update inside the IPPROTO_IPV6 conditional block since it
should only be adjusted when an IP6IP6 tunnel is actually detected.
Simplify the rx path by removing ipv6_skip_exthdr() and checking
ip6h->nexthdr directly, as the flowtable fast path only handles simple
IP6IP6 encapsulation without extension headers.
Drop the tunnel encapsulation limit destination option support from the
tx path to match, since the rx path no longer handles extension headers.
Remove the encap_limit parameter from nf_flow_offload_ipv6_forward(),
nf_flow_tunnel_ip6ip6_push() and nf_flow_tunnel_v6_push(), along with
the ipv6_tel_txoption struct and related headroom/MTU adjustments. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: fsl: fsl_audmix: Validate written enum values
fsl_audmix_put_mix_clk_src() and fsl_audmix_put_out_src()
convert the user-provided enum item with snd_soc_enum_item_to_val()
before checking whether the item is within the enum's item count.
The generic snd_soc_put_enum_double() helper performs that
validation, but these callbacks use the converted value first: the
clock-source path tests it with BIT(), and the output-source path
indexes the prms transition table with it.
Reject out-of-range enum items before converting them. |
| A weakness has been identified in Open Asset Import Library Assimp 17c12da. The affected element is the function Assimp::MDLImporter::ReadFaces_3DGS_MDL7 in the library code/AssetLib/LWO/LWOLoader.h of the component 3DGS MDL7 Model Parser. Executing a manipulation can lead to heap-based buffer overflow. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. This patch is called ee77bb09a42a49843ac85ef64c14d2328b251df1. Applying a patch is advised to resolve this issue. |
| A vulnerability was detected in Edimax EW-7478APC 1.04. Affected is the function formWlSiteSurvey of the file /goform/formWlSiteSurvey. Performing a manipulation of the argument selSSID results in buffer overflow. The attack is possible to be carried out remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. |

| In the Linux kernel, the following vulnerability has been resolved:
bpf: fix BPF_PROG_QUERY OOB write and cgroup backward compat
BPF_PROG_QUERY writes back the 'query.revision' field unconditionally to
userspace. If userspace passes a smaller 'bpf_attr' structure (e.g. 40
bytes, which was the layout before the addition of 'query.revision'),
the kernel performs an out-of-bounds write.
Fix this by propagating the user-provided attribute size 'uattr_size'
down to the cgroup query handlers, and conditionally skipping writing
the revision field to userspace when the provided buffer size is
insufficient.
query.revision in bpf_mprog_query is structurally identical to the
cgroup case: a late tail field, written unconditionally.
But the backward-compat hazard is not the same.
The min-historical-size test is per command, and bpf_mprog_query only
serves attach types that were born with revision in the struct:
- tcx_prog_query -> BPF_TCX_INGRESS/EGRESS
- netkit_prog_query -> BPF_NETKIT_PRIMARY/PEER
tcx, netkit, the revision field, and bpf_mprog_query itself all landed in
the same v6.6 merge window (053c8e1f235d added the mprog query API +
revision; tcx in e420bed02507, netkit in 35dfaad7188c). There has never
been a tcx/netkit BPF_PROG_QUERY userspace that doesn't know about
revision. So for these commands the minimum legitimate struct already
covers offset 56-64 — no old binary can be broken here.
Contrast with cgroup: BPF_PROG_QUERY on cgroup attach types shipped in
2017; revision write-back was bolted on years later (120933984460). That
path has a real population of pre-revision callers. |
