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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/00baeade709fb66da647e8327e8398bb532e30f7","tags":[]},{"url":"https://git.kernel.org/stable/c/74d4085221a7ec5440996af199ccadfa75b9eb0e","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
