CVE-2026-3497 5 Canonical, Debian, Openbsd and 2 more 5 Ubuntu Linux, Debian Linux, Openssh and 2 more 2026-10-15 7.5 High
Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration.
CVE-2025-26466 4 Canonical, Debian, Openbsd and 1 more 5 Ubuntu Linux, Debian Linux, Openssh and 2 more 2026-10-15 5.9 Medium
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.
CVE-2023-40283 4 Canonical, Debian, Linux and 1 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2026-10-15 7.8 High
An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled.
CVE-2023-3777 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2026-10-14 7.8 High
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8.
CVE-2015-8126 9 Apple, Canonical, Debian and 6 more 24 Mac Os X, Ubuntu Linux, Debian Linux and 21 more 2026-10-14 N/A
Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image.
CVE-2015-7575 4 Canonical, Mozilla, Opensuse and 1 more 9 Ubuntu Linux, Firefox, Network Security Services and 6 more 2026-10-14 N/A
Mozilla Network Security Services (NSS) before 3.20.2, as used in Mozilla Firefox before 43.0.2 and Firefox ESR 38.x before 38.5.2, does not reject MD5 signatures in Server Key Exchange messages in TLS 1.2 Handshake Protocol traffic, which makes it easier for man-in-the-middle attackers to spoof servers by triggering a collision.
CVE-2015-5351 4 Apache, Canonical, Debian and 1 more 5 Tomcat, Ubuntu Linux, Debian Linux and 2 more 2026-10-14 N/A
The (1) Manager and (2) Host Manager applications in Apache Tomcat 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M2 establish sessions and send CSRF tokens for arbitrary new requests, which allows remote attackers to bypass a CSRF protection mechanism by using a token.
CVE-2015-5346 4 Apache, Canonical, Debian and 1 more 5 Tomcat, Ubuntu Linux, Debian Linux and 2 more 2026-10-14 N/A
Session fixation vulnerability in Apache Tomcat 7.x before 7.0.66, 8.x before 8.0.30, and 9.x before 9.0.0.M2, when different session settings are used for deployments of multiple versions of the same web application, might allow remote attackers to hijack web sessions by leveraging use of a requestedSessionSSL field for an unintended request, related to CoyoteAdapter.java and Request.java.
CVE-2015-5345 4 Apache, Canonical, Debian and 1 more 5 Tomcat, Ubuntu Linux, Debian Linux and 2 more 2026-10-14 5.3 Medium
The Mapper component in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.30, and 9.x before 9.0.0.M2 processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character.
CVE-2015-5174 4 Apache, Canonical, Debian and 1 more 6 Tomcat, Ubuntu Linux, Debian Linux and 3 more 2026-10-14 N/A
Directory traversal vulnerability in RequestUtil.java in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.65, and 8.x before 8.0.27 allows remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /.. (slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call, as demonstrated by the $CATALINA_BASE/webapps directory.
CVE-2015-0254 3 Apache, Canonical, Redhat 5 Standard Taglibs, Ubuntu Linux, Enterprise Linux and 2 more 2026-10-14 N/A
Apache Standard Taglibs before 1.2.3 allows remote attackers to execute arbitrary code or conduct external XML entity (XXE) attacks via a crafted XSLT extension in a (1) <x:parse> or (2) <x:transform> JSTL XML tag.
CVE-2023-3389 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2026-10-14 7.8 High
A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and 0e388fce7aec40992eadee654193cad345d62663 for 5.15 stable).
CVE-2022-2586 5 Canonical, Linux, Redhat and 2 more 15 Ubuntu Linux, Linux Kernel, Enterprise Linux and 12 more 2026-10-14 5.3 Medium
It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted.
CVE-2022-41222 5 Canonical, Debian, Linux and 2 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2026-10-14 7 High
mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is not held during a PUD move.
CVE-2022-34918 5 Canonical, Debian, Linux and 2 more 14 Ubuntu Linux, Debian Linux, Linux Kernel and 11 more 2026-10-14 7.8 High
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.
CVE-2014-9323 4 Canonical, Debian, Firebirdsql and 1 more 4 Ubuntu Linux, Debian Linux, Firebird and 1 more 2026-10-14 N/A
The xdr_status_vector function in Firebird before 2.1.7 and 2.5.x before 2.5.3 SU1 allows remote attackers to cause a denial of service (NULL pointer dereference, segmentation fault, and crash) via an op_response action with a non-empty status.
CVE-2014-0459 4 Canonical, Debian, Oracle and 1 more 7 Ubuntu Linux, Debian Linux, Jdk and 4 more 2026-10-14 N/A
Unspecified vulnerability in Oracle Java SE 7u51 and 8, and Java SE Embedded 7u51, allows remote attackers to affect availability via unknown vectors related to 2D.

CVE-2022-2588 3 Canonical, Linux, Redhat 9 Ubuntu Linux, Linux Kernel, Enterprise Linux and 6 more 2026-10-14 5.3 Medium
It was discovered that the cls_route filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0.
CVE-2022-1184 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2026-10-14 5.5 Medium
A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel’s filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service.
