CVE-2026-23384

5.5 MEDIUM 0.1% exploit odds Fix listed Other OS & kernel

What it is

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