{"schema":"threatline.record/2","record":{"id":"CVE-2026-98353","aliases":[],"summary":"RDMA/erdma: Use IRQ-safe XArray helpers for QP and CQ tables","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/erdma: Use IRQ-safe XArray helpers for QP and CQ tables\n\nLocked QP and CQ lookups from EQ interrupts can deadlock with\ncreate-path XArray updates. If an interrupt arrives while the create\npath holds the plain xa_lock, the lookup spins forever trying to\nacquire the same lock.\n\nUse IRQ-safe XArray helpers for all QP and CQ create-path updates,\nincluding the GSI QP store and error paths. Initialize both arrays with\nXA_FLAGS_LOCK_IRQ so sleeping allocations preserve interrupt state.","categories":["Operating
