  - mariadb: CONNECT storage engine heap-based buffer overflow (CVE-2022-24052)

  - get_sort_by_table in MariaDB before 10.6.2 allows an application crash via certain subquery uses of ORDER
    BY. (CVE-2021-46657)

  - save_window_function_values in MariaDB before 10.6.3 allows an application crash because of incorrect
    handling of with_window_func=true for a subquery. (CVE-2021-46658)

  - MariaDB before 10.7.2 allows an application crash because it does not recognize that
    SELECT_LEX::nest_level is local to each VIEW. (CVE-2021-46659)

  - MariaDB through 10.5.9 allows an application crash in find_field_in_tables and find_order_in_list via an
    unused common table expression (CTE). (CVE-2021-46661)

  - MariaDB through 10.5.9 allows a set_var.cc application crash via certain uses of an UPDATE statement in
    conjunction with a nested subquery. (CVE-2021-46662)

  - MariaDB through 10.5.13 allows a ha_maria::extra application crash via certain SELECT statements.
    (CVE-2021-46663)

  - MariaDB through 10.5.9 allows an application crash in sub_select_postjoin_aggr for a NULL value of aggr.
    (CVE-2021-46664)

  - MariaDB through 10.5.9 allows a sql_parse.cc application crash because of incorrect used_tables
    expectations. (CVE-2021-46665)

  - MariaDB before 10.6.2 allows an application crash because of mishandling of a pushdown from a HAVING
    clause to a WHERE clause. (CVE-2021-46666)

  - MariaDB before 10.6.5 has a sql_lex.cc integer overflow, leading to an application crash. (CVE-2021-46667)

  - MariaDB through 10.5.9 allows an application crash via certain long SELECT DISTINCT statements that
    improperly interact with storage-engine resource limitations for temporary data structures.
    (CVE-2021-46668)

  - MariaDB through 10.5.9 allows attackers to trigger a convert_const_to_int use-after-free when the BIGINT
    data type is used. (CVE-2021-46669)

  - MariaDB CONNECT Storage Engine Stack-based Buffer Overflow Privilege Escalation Vulnerability. This
    vulnerability allows local attackers to escalate privileges on affected installations of MariaDB.
    Authentication is required to exploit this vulnerability. The specific flaw exists within the processing
    of SQL queries. The issue results from the lack of proper validation of the length of user-supplied data
    prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to
    escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16191.
    (CVE-2022-24048)

  - MariaDB CONNECT Storage Engine Use-After-Free Privilege Escalation Vulnerability. This vulnerability
    allows local attackers to escalate privileges on affected installations of MariaDB. Authentication is
    required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The
    issue results from the lack of validating the existence of an object prior to performing operations on the
    object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in
    the context of the service account. Was ZDI-CAN-16207. (CVE-2022-24050)

  - MariaDB CONNECT Storage Engine Format String Privilege Escalation Vulnerability. This vulnerability allows
    local attackers to escalate privileges on affected installations of MariaDB. Authentication is required to
    exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue
    results from the lack of proper validation of a user-supplied string before using it as a format
    specifier. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code
    in the context of the service account. Was ZDI-CAN-16193. (CVE-2022-24051)

    at /sql/sql_type.cc. (CVE-2022-27456)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2022-27447. Reason: This candidate is a
    reservation duplicate of CVE-2022-27447. Notes: All CVE users should reference CVE-2022-27447 instead of
    this candidate. (CVE-2022-27458)

  - MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_xbstream.cc, when
    an error occurs (stream_ctxt->dest_file == NULL) while executing the method xbstream_open, the held lock
    is not released correctly, which allows local users to trigger a denial of service due to the deadlock.
    Note: The vendor argues this is just an improper locking bug and not a vulnerability with adverse effects.
    (CVE-2022-31621)

  - MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when
    an error occurs (pthread_create returns a nonzero value) while executing the method create_worker_threads,
    the held lock is not released correctly, which allows local users to trigger a denial of service due to
    the deadlock. Note: The vendor argues this is just an improper locking bug and not a vulnerability with
    adverse effects. (CVE-2022-31622)

  - MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when
    an error occurs (i.e., going to the err label) while executing the method create_worker_threads, the held
    lock thd->ctrl_mutex is not released correctly, which allows local users to trigger a denial of service
    due to the deadlock. Note: The vendor argues this is just an improper locking bug and not a vulnerability
    with adverse effects. (CVE-2022-31623)

  - MariaDB Server before 10.7 is vulnerable to Denial of Service. While executing the
    plugin/server_audit/server_audit.c method log_statement_ex, the held lock lock_bigbuffer is not released
    correctly, which allows local users to trigger a denial of service due to the deadlock. (CVE-2022-31624)

  - MariaDB v10.2 to v10.6.1 was discovered to contain a segmentation fault via the component
    Item_subselect::init_expr_cache_tracker. (CVE-2022-32083)

    (CVE-2022-32084)

  - MariaDB v10.2 to v10.7 was discovered to contain a segmentation fault via the component
    Item_func_in::cleanup/Item::cleanup_processor. (CVE-2022-32085)

  - MariaDB v10.2 to v10.7 was discovered to contain a segmentation fault via the component
    Item_args::walk_args. (CVE-2022-32087)

  - MariaDB v10.2 to v10.7 was discovered to contain a segmentation fault via the component
    Exec_time_tracker::get_loops/Filesort_tracker::report_use/filesort. (CVE-2022-32088)

  - MariaDB v10.7 was discovered to contain an use-after-poison in in __interceptor_memset at
    /libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc. (CVE-2022-32091)

  - In MariaDB before 10.9.2, compress_write in extra/mariabackup/ds_compress.cc does not release data_mutex
    upon a stream write failure, which allows local users to trigger a deadlock. (CVE-2022-38791)

  - MariaDB Server before 10.3.34 thru 10.9.3 is vulnerable to Denial of Service. It is possible for function
    spider_db_mbase::print_warnings to dereference a null pointer. (CVE-2022-47015)
