An oversized packet_len\ncan lead to an out-of-bounds read in skb_put_data().\n\nValidate packet_len to ensure it is non-zero and does not exceed\nBTINTEL_PCIE_BUFFER_SIZE - sizeof(*rfh_hdr), logging an error when\ninvalid.\n\nThis issue was reported by Claude Mythos. It can be simulated either by\nusing customized firmware configured to return an invalid packet_len or\nby modifying rfh_hdr->packet_len in the driver before calling\nbtintel_pcie_submit_rx_work().","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/46884c0f92708f1d218fc94d88800227a19b52f8","tags":[]},{"url":"https://git.kernel.org/stable/c/6436e1b5331b1aebf905c13e0880a37032719b75","tags":[]},{"url":"https://git.kernel.org/stable/c/73a50c636425cb9f7ab647b5a97bd14dd5610076","tags":[]},{"url":"https://git.kernel.org/stable/c/ab0159b1f7214ce9bad9862751e4553e635a21b1","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
