Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-26497 is a memory corruption vulnerability, classified under CWE-787, that affects the Samsung Baseband Modem Chipset in Exynos Modem 5123, Exynos Modem 5300, Exynos 980, Exynos 1080, and Exynos Auto T5125. The flaw occurs during processing of Session Description Negotiation for the Video Configuration Attribute and carries a CVSS 3.1 score of 8.6.
An unauthenticated network attacker can trigger the issue remotely with low attack complexity, resulting in memory corruption that yields limited impacts to confidentiality and integrity alongside a high availability impact.
The listed references point to Samsung's semiconductor product pages and its general quality-support product security updates site, which typically host chipset firmware advisories and patches, though no explicit mitigation steps are detailed in the provided references.
EPSS for the CVE reached a peak of 0.0774 after disclosure before receding to the current value of 0.0313.
