| In the Linux kernel, the following vulnerability has been resolved:
ipv6: rpl: fix hdrlen overflow in ipv6_rpl_srh_decompress()
ipv6_rpl_srh_decompress() computes:
outhdr->hdrlen = (((n + 1) * sizeof(struct in6_addr)) >> 3);
hdrlen is __u8. For n >= 127 the result exceeds 255 and silently
truncates. With n=127 (cmpri=15, cmpre=15, pad=0, hdrlen=16):
(128 * 16) >> 3 = 256, truncated to 0 as __u8
The caller in ipv6_rpl_srh_rcv() then places the compressed header
at buf + ((ohdr->hdrlen + 1) << 3). With hdrlen=0 this is buf + 8,
but the decompressed region occupies buf[0..2055] (8-byte header
plus 128 full addresses). The compressed header overlaps the
decompressed data, and ipv6_rpl_srh_compress() writes into this
overlap, corrupting the routing header of the forwarded packet.
The existing guard at exthdrs.c:546 checks (n + 1) > 255, which
prevents n+1 from overflowing unsigned char (the segments_left
field), but does not prevent the computed hdrlen from overflowing
__u8. n=127 passes because 128 <= 255, yet hdrlen=256 does not
fit.
Tighten the bound to (n + 1) > 127. This caps n at 126, giving
hdrlen = (127 * 16) >> 3 = 254, which fits in __u8. The compressed
header then lands at buf + ((254 + 1) << 3) = buf + 2040, exactly
past the decompressed region (buf[0..2039]). No overlap. 127
segments is well beyond any realistic RPL deployment. |
| In the Linux kernel, the following vulnerability has been resolved:
ethtool: coalesce: cap profile updates at NET_DIM_PARAMS_NUM_PROFILES
ethnl_update_profile() walks the ETHTOOL_A_PROFILE_IRQ_MODERATION
nest list with an index 'i' and writes new_profile[i++] without
bounding i. The destination is kmemdup()'d at NET_DIM_PARAMS_NUM_PROFILES
entries (5), but the Netlink nest count is entirely user-controlled.
Netlink policies do not have support for constraining the number
of nested entries (or number of multi-attr entries). |
| In the Linux kernel, the following vulnerability has been resolved:
ethtool: cmis: validate start_cmd_payload_size from module
The CMIS firmware update code reads start_cmd_payload_size from
the module's FW Management Features CDB reply and uses it directly
as the byte count for memcpy. The destination buffer is 112 bytes
(ETHTOOL_CMIS_CDB_LPL_MAX_PL_LENGTH - 8). So a malicious
module (or corrupted response) can cause a OOB write later on in
cmis_fw_update_start_download().
Let's error out. If modules that expect longer LPL writes actually
exist we should revisit.
struct cmis_cdb_start_fw_download_pl's definition has to move,
no change there. |
| In the Linux kernel, the following vulnerability has been resolved:
ethtool: module: call ethnl_ops_complete() on module flash errors
When validate() fails we are skipping over ethnl_ops_complete()
even tho we already called ethnl_ops_begin(). |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: synproxy: refresh tcphdr after skb_ensure_writable
synproxy_tstamp_adjust() rewrites the TCP timestamp option in place
and then patches the TCP checksum via inet_proto_csum_replace4() on
the caller-supplied tcphdr pointer. Both ipv4_synproxy_hook() and
ipv6_synproxy_hook() obtain that pointer with skb_header_pointer()
before calling in, so it may either alias skb->head directly or
point at the caller's on-stack _tcph buffer.
Between obtaining the pointer and using it, the function calls
skb_ensure_writable(skb, optend), which on a cloned or non-linear
skb invokes pskb_expand_head() and frees the old skb->head. After
that point the cached th is stale:
caller (ipv[46]_synproxy_hook)
th = skb_header_pointer(skb, ..., &_tcph)
synproxy_tstamp_adjust(skb, protoff, th, ...)
skb_ensure_writable(skb, optend)
pskb_expand_head() /* kfree(old skb->head) */
...
inet_proto_csum_replace4(&th->check, ...)
/* writes into freed head, or
into the caller's stack copy
leaving the on-wire checksum
stale */
The option bytes are written through skb->data and are fine; only
the checksum update goes through th and so lands in the wrong
place. The result is either a write into freed slab memory or a
packet leaving with a checksum that does not match its payload.
Fix by re-deriving th from skb->data + protoff immediately after
skb_ensure_writable() succeeds, so the subsequent checksum update
targets the linear, writable header. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: Fix use-after-free race in nfc_llcp_recv_cc()
A race condition exists in the NFC LLCP connection state machine where
the connection acceptance packet (CC) can be processed concurrently with
socket release. This can lead to a use-after-free of the socket object.
When nfc_llcp_recv_cc() moves the socket from the connecting_sockets
list to the sockets list, it does so without holding the socket lock.
If llcp_sock_release() is executing concurrently, it might have already
unlinked the socket and dropped its references, which can result in
nfc_llcp_recv_cc() linking a freed socket into the live list.
Fix this by holding lock_sock() during the state transition and list
movement in nfc_llcp_recv_cc(). After acquiring the lock, check if
the socket is still hashed to ensure it hasn't already been unlinked
and marked for destruction by the release path. This aligns the locking
pattern with recv_hdlc() and recv_disc(). |
| In the Linux kernel, the following vulnerability has been resolved:
security/keys: fix missed RCU read section on lookup
Nicholas Carlini reports that the keyring code calls assoc_array_find()
in find_key_to_update() without holding the RCU read lock, while the
assoc_array_gc() code really is designed around removing the node from
the tree and then freeing it after an RCU grace-period.
The regular key handling doesn't see this because holding the keyring
semaphore hides any lifetime issues, but the persistent key handling
uses a different model.
Instead of extending the keyring locking, just do the simple RCU locking
that the assoc_array was designed for. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/oa: Fix exec_queue leak on width check in stream open
In xe_oa_stream_open_ioctl(), when param.exec_q->width > 1 the
function returns -EOPNOTSUPP directly, skipping the existing
err_exec_q cleanup path. The exec_queue reference obtained by
xe_exec_queue_lookup() is leaked.
The exec queue holds a reference on the xe_file, which is only
dropped during queue teardown. The leaked lookup ref is not on
the file's exec_queue xarray, so file close cannot release it.
This keeps both the exec queue and the file private state pinned
indefinitely.
Jump to err_exec_q instead of returning directly so the reference
is released.

| In the Linux kernel, the following vulnerability has been resolved:
gpio: aggregator: remove the software node when deactivating the aggregator
The dynamic software node we create for the aggregator platform device
when using configfs is leaked when the device is deactivated. Destroy it
as the last step in the tear-down path. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: aggregator: fix a potential use-after-free
On error we free aggr->lookups->dev_id before removing the entry from
the lookup table. If a concurrent thread calls gpiod_find() before we
remove the entry, it could iterate over the list and call
gpiod_match_lookup_table() which unconditionally dereferences dev_id
when calling strcmp(). Reverse the order of cleanup. |
| Vulnerability in the Oracle Call Center Technology product of Oracle E-Business Suite (component: RDBMS and UI). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Call Center Technology. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Call Center Technology accessible data as well as unauthorized read access to a subset of Oracle Call Center Technology accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N). |
| A path traversal vulnerability was found in pulpcore. The relative_path_validator function only verifies that content paths do not begin with "/" but fails to block directory traversal sequences such as "../" anywhere in the path. An authenticated administrator can craft a relative_path containing embedded traversal sequences (e.g., "looking/normal/../../../../etc/shadow") that escapes the intended export directory during FilesystemExport operations. Because the file content is also user-controlled (uploaded artifact), this allows arbitrary file write to any location writable by the Pulp service user, potentially leading to service compromise or further system exploitation. |
