CVE-2024-34658

ASLR bypass via out-of-bounds memory read

Published Sep 4, 2024 · Updated Sep 4, 2024

Out-of-bounds read in Samsung Notes before 4.4.21.62 allows local users to disclose memory layout data and bypass ASLR. Samsung has not disclosed the affected parser or input path, and its bulletin groups this identifier with two stack-based out-of-bounds write issues. Local reachability is required by the CVE record, and the bounded documented effect for this identifier is memory-layout disclosure rather than direct code execution.
