CVE-2026-48183: Improper permission handling during buffer operations allows untrusted applications to create memory mappings with inappropriate permissions

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Samsung Semiconductor Exynos 1480 October 2026; Samsung Semiconductor Exynos 1580 October 2026; Samsung Semiconductor Exynos 1680 October 2026.

Low priority for now. Upgrade to Samsung Semiconductor Exynos 1480 October 2026; Samsung Semiconductor Exynos 1580 October 2026; Samsung Semiconductor Exynos 1680 October 2026 or later.
