CVE-2005-2553

12
FAUCET Score

CVE-2005-2553 describes a denial-of-service vulnerability in the Linux kernel versions 2.4.x prior to 2.4.29. Specifically, the find_target function in ptrace32.c fails to properly handle a NULL return, allowing a local attacker to crash the kernel (kernel oops) by executing a 32-bit ltrace program with the -i option against a 64-bit executable. This vulnerability has a low CVSS score of 2.1 (AV:L/AC:L/Au:N/C:N/I:N/A:P), indicating it requires local access and has a low impact of only causing a denial of service. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this decade-old vulnerability.
