CVE-2026-64000
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.
