CVE-2009-2847 is a local information disclosure vulnerability affecting the Linux kernel (versions 2.4 through 2.4.37 and 2.6 before 2.6.31-rc5) on 64-bit systems. The flaw in the do_sigaltstack function allows local users to expose sensitive data from the kernel stack due to uncleared padding bytes. With a CVSS score of 4.9, this vulnerability has low attack complexity and requires local access, leading to a complete compromise of confidentiality but no integrity or availability impact. While not on the KEV catalog or Hot List, an ExploitDB entry (EDB-9352) exists, indicating public exploit code, though there is no evidence of active exploitation or significant community discussion.
