| In the Linux kernel, the following vulnerability has been resolved:
inet: frags: drop fraglist conntrack references
Jakub added a warning in nf_conntrack_cleanup_net_list() to make debugging
leaked skbs/conntrack references more obvious.
syzbot reports this as triggering, and I can also reproduce this via
ip_defrag.sh selftest:
conntrack cleanup blocked for 60s
WARNING: net/netfilter/nf_conntrack_core.c:2512
[..]
conntrack clenups gets stuck because there are skbs with still hold nf_conn
references via their frag_list.
net.core.skb_defer_max=0 makes the hang disappear.
Eric Dumazet points out that skb_release_head_state() doesn't follow the
fraglist.
ip_defrag.sh can only reproduce this problem since
commit 6471658dc66c ("udp: use skb_attempt_defer_free()"), but AFAICS this
problem could happen with TCP as well if pmtu discovery is off.
The relevant problem path for udp is:
1. netns emits fragmented packets
2. nf_defrag_v6_hook reassembles them (in output hook)
3. reassembled skb is tracked (skb owns nf_conn reference)
4. ip6_output refragments
5. refragmented packets also own nf_conn reference (ip6_fragment
calls ip6_copy_metadata())
6. on input path, nf_defrag_v6_hook skips defragmentation: the
fragments already have skb->nf_conn attached
7. skbs are reassembled via ipv6_frag_rcv()
8. skb_consume_udp -> skb_attempt_defer_free() -> skb ends up
in pcpu freelist, but still has nf_conn reference.
Possible solutions:
1 let defrag engine drop nf_conn entry, OR
2 export kick_defer_list_purge() and call it from the conntrack
netns exit callback, OR
3 add skb_has_frag_list() check to skb_attempt_defer_free()
2 & 3 also solve ip_defrag.sh hang but share same drawback:
Such reassembled skbs, queued to socket, can prevent conntrack module
removal until userspace has consumed the packet. While both tcp and udp
stack do call nf_reset_ct() before placing skb on socket queue, that
function doesn't iterate frag_list skbs.
Therefore drop nf_conn entries when they are placed in defrag queue.
Keep the nf_conn entry of the first (offset 0) skb so that reassembled
skb retains nf_conn entry for sake of TX path.
Note that fixes tag is incorrect; it points to the commit introducing the
'ip_defrag.sh reproducible problem': no need to backport this patch to
every stable kernel. |
| In the Linux kernel, the following vulnerability has been resolved:
net: phy: intel-xway: fix OF node refcount leakage
Automated review spotted am OF node reference count leakage when
checking if the 'leds' child node exists.
Call of_put_node() to correctly maintain the refcount. |
| n8n is an open source workflow automation platform. Prior to versions 1.123.18 and 2.5.0, a vulnerability in the file access controls allows authenticated users with permission to create or modify workflows to read sensitive files from the n8n host system. This can be exploited to obtain critical configuration data and user credentials, leading to complete account takeover of any user on the instance. This issue has been patched in versions 1.123.18 and 2.5.0. |
| Identity authentication bypass vulnerability in the window module.
Impact: Successful exploitation of this vulnerability may affect service confidentiality. |
| A weakness has been identified in D-Link DIR-605L and DIR-619L 2.06B01/2.13B01. The affected element is an unknown function of the component DHCP Client Information Handler. Executing a manipulation can lead to information disclosure. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. This vulnerability only affects products that are no longer supported by the maintainer. |
| An Incorrect Initialization of Resource vulnerability in the packet forwarding engine (pfe) of Juniper Networks Junos OS on specific EX Series and QFX Series device allows an unauthenticated, network-based attacker to cause an integrity impact to downstream networks.
When the same family inet or inet6 filter is applied on an IRB interface and on a physical interface as egress filter on EX4100, EX4400, EX4650 and QFX5120 devices, only one of the two filters will be applied, which can lead to traffic being sent out one of these interfaces which should have been blocked.
This issue affects Junos OS on EX Series and QFX Series:
* 23.4 version 23.4R2-S6,
* 24.2 version 24.2R2-S3.
No other Junos OS versions are affected. |
| EventSentry versions prior to 6.0.1.20 contain an unverified password change vulnerability in the account management functionality of the Web Reports interface. The password change mechanism does not require validation of the current password before allowing a new password to be set. An attacker who gains temporary access to an authenticated user session can change the account password without knowledge of the original credentials. This enables persistent account takeover and, if administrative accounts are affected, may result in privilege escalation. |
| ActionForm in Apache Software Foundation (ASF) Struts before 1.2.9 with BeanUtils 1.7 allows remote attackers to cause a denial of service via a multipart/form-data encoded form with a parameter name that references the public getMultipartRequestHandler method, which provides further access to elements in the CommonsMultipartRequestHandler implementation and BeanUtils. |
| A weakness has been identified in Qi-ANXIN QAX Virus Removal up to 2025-10-22. The affected element is the function ZwTerminateProcess in the library QKSecureIO_Imp.sys of the component Mini Filter Driver. Executing a manipulation can lead to improper access controls. The attack is restricted to local execution. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. |
| PowerPoint 95 and 97 allows remote attackers to cause an application to be run automatically without prompting the user, possibly through the slide show, when the document is opened in browsers such as Internet Explorer. |
| Buffer overflow in blackd.exe for BlackICE PC Protection 3.6 and other versions before 3.6.ccb, with application protection off, allows local users to gain system privileges by modifying the .INI file to contain a long packetLog.fileprefix value. |
| Stolen credentials from SSH clients via ssh-agent program, allowing other local users to access remote accounts belonging to the ssh-agent user. |
| AAA authentication on Cisco systems allows attackers to execute commands without authorization. |
| root privileges via buffer overflow in ordist command on SGI IRIX systems. |
| Remote attackers can perform a denial of service in Windows machines using malicious ARP packets, forcing a message box display for each packet or filling up log files. |
| Buffer overflow in the conversion utilities for Japanese, Korean and Chinese Word 5 documents allows an attacker to execute commands, aka the "Malformed Conversion Data" vulnerability. |
| Buffer overflow in POP servers based on BSD/Qualcomm's qpopper allows remote attackers to gain root access using a long PASS command. |
| wimpy_trackplays.php in Plaino Wimpy MP3 Player, possibly 5.2 and earlier, allows remote attackers to insert arbitrary strings into trackme.txt via the (1) trackFile, (2) trackArtist, and (3) trackTitle parameters, which can result in providing false information about songs, occupying excessive disk space with very long parameter values, and storing executable code that might be invoked through a different vulnerability. NOTE: since this issue, as described by the original researcher, is entirely dependent on the presence of another vulnerability, it could be argued that Wimpy cannot be responsible for how its data file is processed by applications outside of its control. Since this issue might only be useful as a facilitator manipulation in another vulnerability, perhaps it should not be included in CVE. |
| The campas CGI program provided with some NCSA web servers allows an attacker to execute arbitrary commands via encoded carriage return characters in the query string, as demonstrated by reading the password file. |
| Denial of service in Sendmail 8.8.6 in HPUX. |
