CVE-2026-98353 Details
Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/erdma: Use IRQ-safe XArray helpers for QP and CQ tables Locked QP and CQ lookups from EQ interrupts can deadlock with create-path XArray updates. If an interrupt arrives while the create path holds the plain xa_lock, the lookup spins forever trying to acquire the same lock. Use IRQ-safe XArray helpers for all QP and CQ create-path updates, including the GSI QP store and error paths. Initialize both arrays with XA_FLAGS_LOCK_IRQ so sleeping allocations preserve interrupt state.
