CVE-2006-0096

High
Published: Translated: NVD NIST

Summary

In Linux kernel versions 2.6.x before 2.6.11 and 2.4.x before 2.4.29, the wan/sdla.c function does not require the CAP_SYS_RAWIO privilege for SDLA firmware upgrades. Although further investigation suggests that exploitation requires root privileges (protected by CAP_NET_ADMIN), the lack of precise privilege distinction may pose a risk.

Risk Assessment

The organization may be exposed to unauthorized modification of SDLA firmware by a local user with limited privileges, potentially leading to system integrity compromise.

Recommendation

It is recommended to update the Linux kernel to version 2.6.11 or later (for 2.6.x series) and 2.4.29 or later (for 2.4.x series) to ensure proper privilege requirements.

Original NVD description (English source)

wan/sdla.c in Linux kernel 2.6.x before 2.6.11 and 2.4.x before 2.4.29 does not require the CAP_SYS_RAWIO privilege for an SDLA firmware upgrade, with unknown impact and local attack vectors. NOTE: further investigation suggests that this issue requires root privileges to exploit, since it is protected by CAP_NET_ADMIN; thus it might not be a vulnerability, although capabilities provide finer distinctions between privilege levels.
