CVE-2011-1769

12
FAUCET Score

CVE-2011-1769 describes a denial-of-service vulnerability in SystemTap 1.4 and earlier versions when unprivileged mode is enabled. Local attackers can trigger a divide-by-zero error and system crash (OOPS) by providing a specially crafted ELF program containing DWARF expressions that are mishandled during context variable access. The vulnerability has a low severity score (CVSS 1.2) due to its local attack vector and high access complexity, resulting in only a partial availability impact. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion or media coverage surrounding this CVE.
