PYSEC-2026-852 OpenStack Neutron Intended MAC-spoofing protection mechanism bypass

The IPTables firewall in OpenStack Neutron up to 7.0.4 and 8.x before 8.1.0 allows remote attackers to bypass an intended MAC-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via 1 a crafted DHCP discovery message or 2 crafted non-IP traffic...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

Oracle Linux 10 / 9 : Unbreakable Enterprise kernel (ELSA-2026-50372)

The remote Oracle Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-50372 advisory. - net/sched: fix pedit partial COW leading to page cache corruption Rajat Gupta CVE-2026-46331 - eventpoll: fix epremove struct eventpoll / struc...

SUSE CVE-2026-53362

In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In ip6appenddata, when the paged-allocation branch is taken MSGMORE / NETIFFSG / large fraglen, alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen;...

CVE-2026-56015

CVE-2026-56015 affects Net::IP::LPM v1.10 and earlier for Perl, enabling a heap out-of-bounds read when adding prefixes with unbounded lengths. The bug arises in addPrefixToTrie() which walks the prefix buffer by prefix_length bits without verifying it against the address width (4 bytes IPv4, 16 ...

EUVD-2026-41541

Net::IP::LPM versions through 1.10 for Perl allow a heap out-of-bounds read via an unbounded prefix length. add passes the prefix string to the trie builder addPrefixToTrie without checking it against the address width. addPrefixToTrie then walks the prefix buffer by prefixlength bits, reading...

ROS-20260703-73-0018

The vulnerability in the kernel-lt is related to the failure to release resources after their useful period has ended. Exploiting this vulnerability allows a remote attacker to cause service interruptions through specially created IPv6 traffic...

PT-2026-55535

Name of the Vulnerable Software and Affected Versions Net::IP::LPM versions prior to 1.11 Description An issue exists where a heap out-of-bounds read can occur due to an unbounded prefix length. The add function passes a prefix string to the addPrefixToTrie function without verifying it against t...

kernel: ipv4: account for fraggap on the paged allocation path

A flaw was found in the Linux kernel's handling of IPv4 network packets. An error in how the kernel accounts for fragmented data during memory allocation can lead to an undersized memory buffer. This memory handling issue could potentially be exploited by a remote attacker to cause a system crash...

kernel: netfilter: nft_inner: Fix IPv6 inner_thoff desync

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftinner module. This vulnerability arises from an incorrect handling of IPv6 inner packet processing, where the transport header offset innerthoff becomes desynchronized from the Layer 4 protocol l4proto. A remot...

foreman: Foreman: Information disclosure via improper validation of nested request parameters

A flaw was found in Foreman. An authenticated user with host-edit permissions could exploit a cross-tenant information disclosure vulnerability. This flaw occurs because the taxonomyscope controller method does not properly validate organization and location IDs from nested request parameters,...
