CVE-2011-4604: The bat_socket_read function in net/batman-adv/icmp_socket.c in the Linux kernel before 3.3 allows remote a...

Security readout for executives and security teams

This flaw is in an old Linux kernel networking component for batman-adv. A crafted batman-adv ICMP packet could corrupt memory, causing denial of service and possibly other unspecified impact. The public record identifies Linux kernels before 3.3, but does not provide CVSS scoring or confirmed exploitation. Exposure is most plausible on legacy Linux systems before kernel 3.3 that use or expose batman-adv packet handling. General servers not using this kernel feature are less likely to be reachable, but the supplied data does not define exact package or distribution scope. Treat this as a targeted legacy-kernel risk, not a broad modern Linux emergency. Prioritize asset discovery and remediation for older systems using batman-adv, especially where network disruption would affect operations. Mitigation focus: Upgrade affected Linux kernels to 3.3 or a vendor-fixed kernel build.; Apply distribution security updates where legacy kernels are still maintained.; Use the upstream commit reference to confirm whether backported kernels contain the fix..
