A user-mode, memory-protected module can thereby write up to nine words, eight of its choosing, or 25 with floating-point state, into memory immediately below any region it may write, and read back what is stored there.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7,"severity":"high","source":"CNA: eclipse","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":7,"severity":"high","source":"NVD: emo@eclipse.org","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"}],"modifiedAt":1793639855760,"publishedAt":1793632218233,"references":[{"source":"CNA: eclipse","tags":[],"url":"https://github.com/eclipse-threadx/threadx/security/advisories/GHSA-c38r-v552-gh5g"},{"source":"CNA: eclipse","tags":[],"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/503"},{"source":"emo@eclipse.org","tags":[],"url":"https://github.com/eclipse-threadx/threadx/security/advisories/GHSA-c38r-v552-gh5g"},{"source":"emo@eclipse.org","tags":[],"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/503"},{"source":"GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/eclipse-threadx/threadx/security/advisories/GHSA-c38r-v552-gh5g"}],"remediation":[{"kind":"fix","source":"GitHub GHSA-c38r-v552-gh5g","text":"ThreadX (eclipse threadx): GitHub reports patched versions 6.5.2.202603b.
