CVE-2010-2955: The cfg80211_wext_giwessid function in net/wireless/wext-compat.c in the Linux kernel before 2.6.36-rc3-nex...

Security readout for executives and security teams

CVE-2010-2955 is an old Linux kernel information leak. A local user could cause the wireless compatibility code to return data from kernel heap memory. This is not described as remote code execution, but kernel memory disclosure can expose sensitive data and support later attacks on shared systems. Exposure is most likely on older Linux systems with affected kernel builds, especially Ubuntu, Red Hat, and SUSE systems covered by the cited advisories. The source bundle does not provide exact package versions or CPEs, so validate against vendor advisories and running kernel packages. Treat this as a patch-management item with elevated priority for legacy or shared Linux systems. It is lower urgency than a remotely exploitable kernel bug, but kernel memory disclosure can still weaken system isolation and increase breach impact. Mitigation focus: Apply the relevant vendor kernel update for affected Linux distributions.; Reboot systems so the patched kernel is actually running.; Prioritize shared, multi-user, and untrusted shell environments..
