CVE-2007-4308

11
FAUCET Score

CVE-2007-4308 describes a vulnerability in the aac_cfg_open and aac_compat_ioctl functions within the SCSI layer ioctl path of the aacraid driver in the Linux kernel before version 2.6.23-rc2. This flaw allows local users to potentially cause a denial of service or escalate privileges due to a lack of permission checks for ioctl operations. With a CVSS score of 1.9 (AV:L/AC:M/Au:N/C:N/I:N/A:P), it is considered low severity, requiring local access and moderate attack complexity to achieve a partial impact on availability. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
