"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/ionic: Fix kernel stack leak in ionic_create_cq()\n\nstruct ionic_cq_resp resp {\n __u32 cqid[2]; // offset 0 - PARTIALLY SET (see below)\n __u8 udma_mask; // offset 8 - SET (resp.udma_mask = vcq->udma_mask)\n __u8 rsvd[7]; // offset 9 - NEVER SET <- LEAK\n};\n\nrsvd[7]: 7 bytes of stack memory leaked unconditionally.\n\ncqid[2]: The loop at line 1256 iterates over udma_idx but skips indices\nwhere !(vcq->udma_mask & BIT(udma_idx)). The array has 2 entries but\nudma_count could be 1, meaning cqid[1] might never be written via\nionic_create_cq_common(). If udma_mask only has bit 0 set, cqid[1] (4\nbytes) is also leaked. So potentially 11 bytes leaked."
