CyberRota Analysis
AI-GeneratedA critical vulnerability in the Linux kernel affects the handling of supervision frames in the HSR (High-availability Seamless Redundancy) protocol, potentially leading to out-of-bounds access due to improper linearization of the TLV header. This flaw could be exploited to execute arbitrary code or crash the system, posing significant risks to network stability and security. Organizations using Linux-based systems, especially those relying on HSR for network redundancy, should prioritize patching this vulnerability immediately.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: net: hsr: fix potential OOB access in supervision frame handling Ensure the entire TLV header is linearized before access by adding sizeof(struct hsr_sup_tlv) to the pskb_may_pull() calls. Without this, a truncated frame could cause an out-of-bounds access.
