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...

kernel: tcp: fix potential race in tcp_v6_syn_recv_sock()

A flaw was found in the Linux kernel. A race condition exists in the TCP Transmission Control Protocol IPv6 Internet Protocol version 6 socket handling, specifically within the tcpv6synrecvsock function. This occurs because a child socket becomes visible in the TCP hash table before its...

CVE-2026-10540

CVE-2026-10540 affects Control-M/Enterprise Manager (unsupported versions 9.0.20.x and potentially earlier). The vulnerability stems from weak protections for stored password hashes, potentially allowing offline password recovery if credential data is obtained. The CVSS metrics indicate a Local a...

CVE-2026-56016

CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources. The generateid method builds the session id from a MD5 digest of the process id, the epoch time, and the built-in rand function. All three are predictable, low-entropy sources: the PID i...

CVE-2026-54901

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, Oj::Parser in usual mode does not mark arrayclass and hashclass references during garbage collection, leading to Use-After-Free. If GC runs after the class is assigned but before a parse,...

CVE-2026-54902

CVE-2026-54902 affects the Ruby gem Oj (Optimized JSON). In SAJ mode prior to 3.17.2, the parser’s key caching can be GC’d while the C parser still references it, causing a Use-After-Free and a segfault when a freed VALUE is accessed. The issue is fixed in version 3.17.2. Exploitation details are...

CVE-2026-54902 Oj: Use-After-Free in Oj::Parser SAJ Long Key Callback

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. Prior to version 3.17.2, is vulnerable to Use-After-Free when in SAJ mode. The Oj::Parser does not protect cached object keys ≥ 35 bytes from garbage collection, and a Ruby callback that triggers GC inside hashend ca...

CVE-2026-54901 Oj: Use-After-Free in Oj::Parser array_class/hash_class GC Marking

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, Oj::Parser in usual mode does not mark arrayclass and hashclass references during garbage collection, leading to Use-After-Free. If GC runs after the class is assigned but before a parse,...

CVE-2026-54901

Oj (Optimized JSON) Ruby gem contains a Use-After-Free in Oj::Parser in normal mode prior to 3.17.2: during GC, array_class/hash_class refs may be reclaimed, leaving a dangling VALUE for the next parse and causing a segfault. Fixed in version 3.17.2. Affected: Oj::Parser parsing flow; trigger is ...

CVE-2026-13455

A flaw was found in PostgreSQL Anonymizer. Unprivileged masked users can repeatedly call the anon.hash function to collect seed and hash output pairs. This allows an attacker to perform an offline brute-force attack to deduce the salt, potentially leading to information disclosure. Mitigation...

CVE-2026-13455

PostgreSQL Anonymizer contains a vulnerability that allows unprivileged masked users to repeatedly call the anon.hash function and collects seed, hashoutput pairs to perform an offline brute-force attack and deduce the salt. The problem is resolved in PostgreSQL Anonymizer 3.1.2 and later version...

CVE-2026-58015 Glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive

A flaw was found in GLib. The D-Bus client-side implementation of the DBUSCOOKIESHA1 SASL authentication mechanism does not validate the cookiecontext parameter received from the server. A malicious D-Bus server can supply a cookiecontext containing path traversal sequences, causing the client to...

CVE-2026-53692

Redeight CMS version 1.0 uses the MD5 algorithm without a salt to store user passwords. Because MD5 is a cryptographically broken algorithm and lacks salting, attackers who obtain the password hashes can trivially reverse them using rainbow tables, leading to the exposure of plaintext credentials...
