Privilege escalation via invalid pointer dereference in Mozilla Firefox's Graphics component allows a remote attacker to gain elevated privileges within the browser context. Affected versions are all Firefox releases prior to 154 and all Firefox ESR releases prior to 153.1, with patches confirmed in Mozilla advisories mfsa2026-74 and mfsa2026-77. No public exploit identified at time of analysis, and CISA's SSVC framework rates exploitation status as none with the attack not automatable, though technical impact is assessed as total.
Information disclosure in Mozilla Firefox via CWE-763 (Release of Invalid Pointer or Reference) allows network-based attackers to read limited memory contents from affected browser instances. All Firefox versions prior to 152.0.6 are affected. Publicly available exploit code exists, though Mozilla reports no confirmed attacks in the wild; user interaction is required to trigger the flaw, moderately reducing real-world exposure.
Memory-corruption crash (and potential code execution) in Foxit PDF Reader and Foxit PDF Editor occurs when a PDF's embedded JavaScript writes annotation attributes without sufficient object-type and argument validation, corrupting the internal annotation structure so the application faults during subsequent object release (CWE-763). Local exploitation requires a user to open a crafted PDF; there is no public exploit identified at time of analysis and the flaw is not in CISA KEV. The vendor rates full confidentiality, integrity, and availability impact (CVSS 7.8), though Foxit tags it as Denial of Service.
Local privilege escalation / memory corruption in the Linux kernel's netfilter NAT subsystem (introduced in v5.14) arises because nf_nat_register_fn() freed nf_hook_ops structures immediately rather than deferring the release via RCU. Because the v5.14-era nfnetlink_hook feature lets userspace dump active netfilter hooks by peeking into the ops blob, a concurrent dump racing the NAT (un)register error path can access ops memory after it is freed. No public exploit has been identified at time of analysis and EPSS is low (0.17%), but the high-impact CVSS vector reflects a use-after-free class flaw in a core kernel subsystem.
Memory corruption in the Linux kernel's TIPC (Transparent Inter-Process Communication) protocol stack allows remote attackers to trigger a double-free in tipc_buf_append() during message reassembly, where tipc_msg_validate() may reallocate and free the working skb while the error path frees a now-stale pointer. Affected systems are those running a vulnerable kernel (introduced around 4.15-era code, present across 5.10-7.0 branches) with the TIPC subsystem in use; successful exploitation can crash the kernel and, depending on heap conditions, potentially lead to privilege escalation. There is no public exploit identified at time of analysis, EPSS risk is low (0.18%, 7th percentile), and it is not listed in CISA KEV.
Denial of service in the Cpanel::JSON::XS Perl module before version 4.41 allows remote attackers to crash any caller that decodes a UTF-8 BOM prefixed JSON document with a throwing filter callback. The flaw arises from a missed pointer restoration when decode_json aborts via a Perl exception, leaving the input scalar with a corrupted SvPVX pointer that fatally aborts the interpreter on later free. No public exploit identified at time of analysis, and EPSS is very low (0.02%), but CISA SSVC marks the issue as automatable with partial technical impact.
Denial-of-service via invalid pointer dereference in Samsung Open Source Escargot JavaScript engine affects the specific commit 590345cc6258317c5da850d846ce6baaf2afc2d3, allowing a locally-present attacker to crash the runtime through crafted JavaScript. The root cause (CWE-763) involves unconditional dereference of a potentially invalid or null error pointer in the resultOrErrorToString path, triggerable via nested eval/throw/finally patterns that induce GC allocation during exception handling. No public exploit code exists and no CISA KEV listing is present at time of analysis.
Buffer overflow in Hitachi JP1/IT Desktop Management suite and Job Management Partner 1 software on Windows allows local authenticated users to cause denial of service by triggering memory corruption in affected manager and client components. The vulnerability spans multiple product lines and versions, with CVSS 5.5 indicating moderate local attack surface; active exploitation status not confirmed.
Microsoft FastTube 1.0.1.0 contains a denial of service vulnerability that allows local attackers to crash the application by submitting an excessively long string to the search functionality. Rated medium severity (CVSS 6.9), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
ImageMagick versions prior to 7.1.2-13 fail to properly initialize buffer elements in the BilateralBlurImage method, leading to invalid pointer dereference and potential denial of service when memory allocation fails. An attacker can exploit this through network vectors to crash affected applications or trigger undefined behavior with high complexity requirements. A patch is available in version 7.1.2-13 and later.
