CVE-2009-0029

18
FAUCET Score

CVE-2009-0029 describes an ABI vulnerability in Linux kernel versions 2.6.28 and earlier on specific 64-bit architectures (s390, powerpc, sparc64, and mips), affecting products like Debian Linux. This flaw arises from the kernel's inability to verify proper sign extension of 32-bit arguments in 64-bit registers from user-mode applications. With a CVSS score of 7.2, this vulnerability is considered high severity, allowing local users to potentially cause a denial of service (crash) or gain privileges through crafted system calls. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely targeted.
