Description

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Bound VP index against VP_CTRL IOCB bitmap size The VP control IOCB selects its target virtual port by setting one bit in vp_idx_map, a fixed 16-byte (128-bit) array in both vp_ctrl_entry_24xx and vp_ctrl_entry_24xx_ext. qla25xx_ctrlvp_iocb() computes map = (vp_index - 1) / 8 and writes vce->vp_idx_map[map] without checking that map stays within the array. max_npiv_vports is taken from firmware and only sanitized to a MIN_MULTI_ID_FABRIC-aligned boundary, so it can legitimately be 191 or 255, and qla24xx_control_vp() only rejects vp_index >= max_npiv_vports. A vp_index above 128 therefore yields map >= 16 and an out-of-bounds write of up to 16 bytes past vp_idx_map, corrupting the trailing IOCB fields (or the adjacent request-ring slot on the 64-byte layout). Reject a vp_index that cannot be represented in the IOCB bitmap in qla24xx_control_vp(), and add a defensive ARRAY_SIZE() guard in qla25xx_ctrlvp_iocb() before the write. Adapters that report the usual 63 or 127 NPIV vports are unaffected.
