  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hsr: fix potential OOB access in supervision frame handling\n\nEnsure the entire TLV header is linearized before access by adding\nsizeof(struct hsr_sup_tlv) to the pskb_may_pull() calls. Without this,\na truncated frame could cause an out-of-bounds access.",
