The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.
CVE-2021-36222 5 Debian, Mit, Netapp and 2 more 8 Debian Linux, Kerberos 5, Active Iq Unified Manager and 5 more 2026-10-14 7.5 High
ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash. This occurs because a return value is not properly managed in a certain situation.
CVE-2021-4209 3 Gnu, Netapp, Redhat 6 Gnutls, Active Iq Unified Manager, Hci Bootstrap Os and 3 more 2026-10-14 6.5 Medium
A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances.

A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability.
CVE-2020-35525 2 Redhat, Sqlite 2 Enterprise Linux, Sqlite 2026-10-14 7.5 High
In SQlite 3.31.1, a potential null pointer derreference was found in the INTERSEC query processing.
CVE-2020-25692 3 Netapp, Openldap, Redhat 6 Cloud Backup, Solidfire Baseboard Management Controller, Solidfire Baseboard Management Controller Firmware and 3 more 2026-10-14 7.5 High
A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs. An unauthenticated attacker could remotely crash the slapd process by sending a specially crafted request, causing a Denial of Service.
CVE-2020-24659 5 Canonical, Fedoraproject, Gnu and 2 more 5 Ubuntu Linux, Fedora, Gnutls and 2 more 2026-10-14 7.5 High
An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.
CVE-2020-13632 9 Broadcom, Canonical, Debian and 6 more 14 Fabric Operating System, Ubuntu Linux, Debian Linux and 11 more 2026-10-14 5.5 Medium
ext/fts3/fts3_snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo() query.
CVE-2020-13435 3 Fedoraproject, Redhat, Sqlite 3 Fedora, Enterprise Linux, Sqlite 2026-10-14 5.5 Medium
SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.
CVE-2020-9327 6 Canonical, Netapp, Oracle and 3 more 12 Ubuntu Linux, Cloud Backup, Communications Messaging Server and 9 more 2026-10-14 7.5 High
In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and segmentation fault because of generated column optimizations.
CVE-2019-19926 8 Debian, Netapp, Opensuse and 5 more 13 Debian Linux, Cloud Backup, Backports Sle and 10 more 2026-10-14 7.5 High
multiSelect in select.c in SQLite 3.30.1 mishandles certain errors during parsing, as demonstrated by errors from sqlite3WindowRewrite() calls. NOTE: this vulnerability exists because of an incomplete fix for CVE-2019-19880.
CVE-2019-19923 8 Debian, Netapp, Opensuse and 5 more 14 Debian Linux, Cloud Backup, Backports Sle and 11 more 2026-10-14 7.5 High
flattenSubquery in select.c in SQLite 3.30.1 mishandles certain uses of SELECT DISTINCT involving a LEFT JOIN in which the right-hand side is a view. This can cause a NULL pointer dereference (or incorrect results).
CVE-2019-19880 8 Debian, Netapp, Opensuse and 5 more 13 Debian Linux, Cloud Backup, Backports Sle and 10 more 2026-10-14 7.5 High
exprListAppendList in window.c in SQLite 3.30.1 allows attackers to trigger an invalid pointer dereference because constant integer values in ORDER BY clauses of window definitions are mishandled.
CVE-2019-9937 1 Sqlite 1 Sqlite 2026-10-14 N/A
In SQLite 3.27.2, interleaving reads and writes in a single transaction with an fts5 virtual table will lead to a NULL Pointer Dereference in fts5ChunkIterate in sqlite3.c. This is related to ext/fts5/fts5_hash.c and ext/fts5/fts5_index.c.
CVE-2019-9923 2 Gnu, Opensuse 2 Tar, Leap 2026-10-14 7.5 High
pax_decode_header in sparse.c in GNU Tar before 1.32 had a NULL pointer dereference when parsing certain archives that have malformed extended headers.
CVE-2019-19242 5 Canonical, Oracle, Redhat and 2 more 5 Ubuntu Linux, Mysql Workbench, Enterprise Linux and 2 more 2026-10-14 5.9 Medium
SQLite 3.30.1 mishandles pExpr->y.pTab, as demonstrated by the TK_COLUMN case in sqlite3ExprCodeTarget in expr.c.
CVE-2018-14404 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Ansible Tower and 3 more 2026-10-14 6.5 Medium
A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application.
CVE-2026-107733 1 Sumatrapdfreader 1 Sumatrapdf 2026-10-14 N/A
SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, FrameOnCommand() handles CmdExec by passing a null current-tab pointer to RunWithExe(), which dereferences WindowTab::filePath. A local process in the same interactive Windows session, at an integrity level greater than or equal to SumatraPDF's under Windows UIPI, can dispatch CmdExec over DDE or WM_COPYDATA while no document tab is open, causing abrupt process termination and loss of unsaved state. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.
