  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrbd: reject data replies with an out-of-range payload size\n\nrecv_dless_read() receives a P_DATA_REPLY from a peer into the bio of an\noutstanding read request. The peer-supplied payload length reaches it as\nthe signed int data_size, and two peer-controlled inputs can make it\nnegative. With a negotiated data-integrity-alg the digest length is\nsubtracted first, so a reply whose payload is smaller than the digest\nunderflows data_size. With no integrity algorithm (the default) data_size\nis assigned from the unsigned h95/h100 wire length and drbdd() never\nbounds it for a payload-carrying command, so a length above INT_MAX casts\nit negative; this path needs no non-default feature. The bio receive loop\nthen computes expect = min_t(int, data_size, bv_len), which is negative,\nand drbd_recv_all_warn(mapped, expect) receives with a size_t of SIZE_MAX\ninto the first mapped page.\n\nThe sibling receive path read_in_block() is not affected: it uses an\nunsigned size and rejects it against DRBD_MAX_BIO_SIZE before receiving.\nReject a data reply whose size is negative after the optional digest\nsubtraction, covering both triggers.\n\nImpact: a malicious or man-in-the-middle DRBD peer copies attacker-chosen\nbytes past a bio page in the receiver, corrupting kernel memory. A node\nthat reads from its peer (a diskless node, or read-balancing to the peer)\nis exposed in the default configuration; data-integrity-alg is not\nrequired.",
