Lexbor is a web browser engine library. Prior to 2.7.0, a type‑confusion vulnerability exists in Lexbor’s HTML fragment parser. When ns = UNDEF, a comment is created using the “unknown element” constructor. The comment’s data are written into the element’s fields via an unsafe cast, corrupting the qualified_name field. That corrupted value is later used as a pointer and dereferenced near the zero page. This vulnerability is fixed in 2.7.0.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-c4d1ca4f16 advisory.

  - In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6,
    when SoapServer is configured with SOAP_PERSISTENCE_SESSION, the handler object is persisted across
    requests via session storage. However, in the case SOAP requests results in an error, the persistance is
    handled incorrectly, resulting in freeing the object while keeping a pointer to it, which may lead to use-
    after-free. This may lead to memory corruption, information disclosure, or process crashes, with
    confidentiality, integrity, and availability impact on the vulnerable system. (CVE-2026-7261)

  - In PHP versions 8.4.* before 8.4.21 and 8.5.* before 8.5.6, when an encoding name containing an embedded
    NUL byte is passed to mb_convert_encoding() or related mbstring functions, the code incorrectly assumes
    that when strncasecmp() returns 0 it means the strings have the same length. This can lead to out-of-
    bounds read of global memory, potentially causing a crash or information disclosure or crash. Affected
    functions include mb_convert_encoding(), mb_detect_encoding(), mb_convert_variables(), and
    mb_detect_order(), as well as the mbstring.detect_order and mbstring.http_output INI settings.
    (CVE-2026-6104)

  - In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the
    SOAP extension's object deduplication mechanism stores pointers to PHP objects in a global map without
    incrementing their reference counts. When an apache:Map node contains duplicate keys, processing the
    second entry overwrites the first in the temporary result map, freeing the original PHP object while its
    stale pointer remains in the map. A subsequent href reference to the freed node can copy the dangling
    pointer into the result. As PHP string allocations can reclaim the freed memory region, an attacker with
    control over the SOAP request body can exploit this use-after-free to achieve remote code execution.
    (CVE-2026-6722)

  - In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, 8.5.* before 8.5.6, due to
    improper sanitation of user data, it allows an attacker to compose an URL, which will cause the target to
    execute arbitrary JavaScript code (XSS) on the target's machine when the target is viewing the PHP-FPM
    status page. (CVE-2026-6735)

  - In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6,
    some functions, including urldecode(), pass signed char to ctype functions (like isxdigit()). On the
    systems with default signed char and optimized table-lookup ctype functions - such as NetBSD - this can
    lead to accessing array with negative offset, which can trigger a denial of service. (CVE-2026-7258)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Lexbor is a web browser engine library. Prior to 2.7.0, a typeconfusion vulnerability exists in Lexbor's     HTML fragment parser. When ns = UNDEF, a comment is created using the unknown element constructor. The     comment's data are written into the element's fields via an unsafe cast, corrupting the qualified_name     field. That corrupted value is later used as a pointer and dereferenced near the zero page. This     vulnerability is fixed in 2.7.0. (CVE-2026-29079)

Note that Nessus relies on the presence of the package as reported by the vendor.
