Threats
Impact
Moderate
A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.

1 product, the same list as for
CVE-2025-5222
Threats
Impact
Important
A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file.

Fixed
1 product, the same list as for
CVE-2025-5222
Threats
Impact
Moderate
A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install it into the local trust store without proper verification. An attacker with the ability to intercept or redirect network traffic could exploit this behavior to supply a malicious certificate authority certificate, potentially allowing interception or spoofing of trusted communications.
8.0 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2025-5222
Threats
Impact
Important
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
6.5 (Medium)
Affected products
Fixed
1 product, the same list as for
CVE-2025-5222
Threats
Impact
Moderate
A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service.
9.0 (Critical)
Affected products
Fixed
1 product, the same list as for
CVE-2025-5222
Threats
Impact
Important
A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior.

A flaw was found in SQLite's FTS5 full-text search extension. This vulnerability involves memory corruption, specifically an out-of-bounds read and a heap buffer overflow, which can be triggered by supplying a crafted database with malformed FTS5 page data. When an FTS5 MATCH query is executed against such a database, an attacker can cause process crashes, memory exhaustion, or achieve arbitrary code execution, potentially compromising the system.

1 product, the same list as for
CVE-2025-5222
Threats
Impact
Important
A flaw was found in SQLite, specifically within its FTS5 full-text search extension. Attackers can exploit a heap-based buffer overflow by providing a specially crafted database. This crafted database contains malicious metadata that triggers an integer underflow during FTS5 MATCH query processing. Successful exploitation of this vulnerability can lead to a crash of the application or allow for arbitrary code execution.

CVE-2025-5222
Threats
Impact
Important
A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.

1 product, the same list as for
CVE-2025-5222
Threats
Impact
Moderate
A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2025-5222
Threats
Impact
Important
A flaw was found in systemd, a system and service manager. An unprivileged user can exploit this vulnerability by making an Inter-Process Communication (IPC) API call with spurious data. In older versions (v249 and earlier), this can lead to stack overwriting with attacker-controlled content, potentially enabling arbitrary code execution or privilege escalation. In newer versions (v250 and later), the flaw causes systemd to assert and freeze, resulting in a Denial of Service (DoS).

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2025-5222
Threats
Impact
Important
A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.

CVE-2025-5222
Threats
Impact
Important
A flaw was found in Vim, an open-source command-line text editor. This command injection vulnerability occurs during tag file processing. A local user could craft a malicious tags file containing backtick syntax in the filename field. When Vim resolves a tag from this file, it executes the embedded command via the system shell, leading to arbitrary code execution with the privileges of the running user.
7.3 (High)

Fixed
1 product, the same list as for
CVE-2025-5222
Threats
Impact
Moderate
A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service.

Impact
Important
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.

A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

"text": "Red Hat Product Security has assessed this CVE as 7.5 CVSS with Moderate security Impact. This assessment reflects the library\u0027s typical deployment within enterprise software, where libarchive is frequently embedded into automated, network-accessible services that receive and process archives originating from remote sources. In these environments, a specially crafted RAR5 archive may be delivered and processed automatically without requiring direct user interaction, allowing a remote attacker to trigger the vulnerability and cause the affected application or service processing the archive to terminate unexpectedly, resulting in a denial of service.\n\nFrom a standalone library perspective, however, the vulnerable code is only reached when an application opens and processes a crafted RAR5 archive. Evaluating libarchive in isolation, without considering downstream deployment models, the vulnerability more closely aligns with a CVSS score of 5.5-CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H (Moderate), reflecting an Attack Vector of Local (AV:L) and User Interaction Required (UI:R). This is because the crafted archive must first be delivered to and processed by a local application before the vulnerable parsing logic is executed. \n\nRed Hat\u0027s assigned score instead reflects the operational deployment of libarchive in automated, network-facing workloads in downstream environment models rather than the standalone library in isolation.\n\n```\n\nThis vulnerability only affects libarchive releases that include support for the RAR5 archive format. RAR5 support was first introduced upstream in libarchive 3.4.0 (https://github.com/libarchive/libarchive/wiki/ReleaseNotes#libarchive-340). Earlier libarchive releases do not contain the vulnerable RAR5 parsing code and are therefore not affected.\n\nRed Hat Enterprise Linux 6, 7, and 8 ship Libarchive versions prior to v3.4.0 that do not include RAR5 support and are therefore not affected.\n\n```",

The vulnerability can be triggered by an unauthenticated attacker sending crafted DTLS handshake fragments, requiring no prior access or interaction. It leads to an out-of-bounds read caused by an integer underflow in fragment reassembly, operating entirely on attacker-controlled input. Such flaws in low-level protocol parsing are particularly serious, as they may result in disclosure of sensitive process memory, including cryptographic or session-related data, and can also cause reliable application crashes leading to denial of service. Given that DTLS is commonly used in network-facing services such as VPNs and real-time communication systems, the exposure surface is broad. The combination of unauthenticated remote exploitation, memory safety violation, and potential confidentiality and availability impact justifies classifying this issue as high severity rather than moderate.",

"text": "A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.",

"text": "This vulnerability should be classified as an important flaw rather than moderate because it exposes a pre-authentication, remotely reachable heap buffer overflow in the DTLS handshake processing path, which is part of the core protocol handling logic and commonly exposed in network-facing services. The flaw enables an attacker to inject controlled data at attacker-chosen offsets and sizes beyond allocated heap boundaries by exploiting inconsistent message_length handling across fragments, effectively creating a constrained but meaningful heap write primitive. Unlike benign memory safety bugs, this condition is deterministically triggerable with a small number of crafted packets and no environmental dependencies for denial-of-service, and it targets a long-lived parsing state where memory corruption can affect adjacent heap structures. Even if reliable code execution requires additional heap manipulation or layout knowledge, the combination of remote reachability, lack of authentication, controlled memory corruption capability, and trivial crashability significantly elevates the risk profile beyond moderate severity. In real-world deployments, such primitives are often sufficient to enable heap grooming and exploitation chains, particularly in services that repeatedly process attacker-controlled input, making this a materially important security flaw.",
