Rebasing 5.87, I think bd8989620ed6 missed one read in parse_media_element() (profiles/audio/avrcp.c): ```c if (!parse_media_name(operands, len, 11, name, &namesize)) return NULL; uid = get_be64(&operands[0]); count = operands[13 + namesize]; ``` parse_media_name() only checks len >= name_len_offset + 2 + namesize, so all we know is len >= 13 + namesize. At len == 13 + namesize, operands[13 + namesize] is operands[len], one byte past the element, and both len and the declared name length come from the peer on the browsing channel. avrcp_list_items_rsp() allows i + len == operand_count, so the read lands at buf[ret] in the g_malloc0(MAX(imtu, omtu)) buffer from avctp.c. Usually that's a leftover byte still inside the allocation,t's only past the buffer when the response fills the MTU and imtu >= omtu. Reproducible: Always Steps to Reproduce: Found by reading the code, not from a crash. Additional Information: Affects 5.87 and any 5.86 carrying bd8989620ed6. Guard I had in mind: ```c if (len <= 13 + namesize) return NULL; ```
Before I post it upstream, do you want to comment on: https://gist.github.com/hadess/88da1bdb4c8e6930d052c8f150b10701 ? I can also put in a longer name credit.
