CVE Summary Severity CVSS EPSS Priority Signals
CVE-2017-5753 Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Rated medium severity (CVSS 5.6). Public exploit code available and EPSS exploitation probability 94.3%. MEDIUM 5.6 94.3% 142
PoC
CVE-2017-5754 Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel. Rated medium severity (CVSS 5.6). Epss exploitation probability 89.7%. MEDIUM 5.6 89.7% 118
PoC
CVE-2018-3639 Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. Public exploit code available and EPSS exploitation probability 46.0%. MEDIUM 5.5 46.0% 94
PoC
CVE-2021-44732 Mbed TLS before 3.0.1 has a double free in certain out-of-memory conditions, as demonstrated by an mbedtls_ssl_set_session() failure. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available. CRITICAL 9.8 1.0% 70
PoC No patch
CVE-2022-35409 An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available. CRITICAL 9.1 2.0% 68
PoC No patch
CVE-2025-10263 Cross-exception-level write access in multiple Arm CPU cores including Cortex-A76 through Cortex-X925, Neoverse N1/N2/V1/V2/V3/V3AE, and C1-Ultra/Premium designs allows a lower-privileged context to modify resources owned by a higher exception level due to a race condition (CWE-362). Tracked also as Xen XSA-493 and EUVD-2025-210084, the issue carries a CVSS of 9.1 reflecting high confidentiality and integrity impact, though there is no public exploit identified at time of analysis and the EPSS score of 0.02% (4th percentile) indicates very low predicted exploitation probability. CRITICAL 9.1 0.0% 66
PoC
CVE-2021-28663 The Arm Mali GPU kernel driver allows privilege escalation or information disclosure because GPU memory operations are mishandled, leading to a use-after-free. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available. HIGH 8.8 12.1% 64
KEV PoC No patch
CVE-2022-38181 The Arm Mali GPU kernel driver allows unprivileged users to access freed memory because GPU memory operations are mishandled. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available. HIGH 8.8 12.6% 64
KEV PoC No patch
CVE-2017-2784 An exploitable free of a stack pointer vulnerability exists in the x509 certificate parsing code of ARM mbed TLS before 1.3.19, 2.x before 2.1.7, and 2.4.x before 2.4.2. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. Public exploit code available and no vendor patch available. HIGH 8.1 3.1% 64
PoC No patch
CVE-2025-52496 Mbed TLS before 3.6.4 has a race condition in AESNI detection if certain compiler optimizations occur. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery. HIGH 7.8 0.0% 59
PoC
CVE-2023-5427 Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user to make. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available. HIGH 7.8 0.3% 59
PoC No patch
CVE-2022-46393 An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available. CRITICAL 9.8 0.9% 50
No patch
CVE-2026-34877 Mbed TLS versions 2.19.0 through 3.6.5 and 4.0.0 allow remote code execution through memory corruption when attackers modify serialized SSL context or session structures. The vulnerability stems from insufficient validation of deserialized data, enabling arbitrary code execution on systems using affected versions. CISA KEV status and active exploitation data not confirmed in provided intelligence. CRITICAL 9.8 0.1% 49
