Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved: dmaengine: xilinx: xdma: Fix regmap init error handling devm_regmap_init_mmio returns an ERR_PTR() upon error, not NULL. Fix the error check and also fix the error message. Use the error code from ERR_PTR() instead of the wrong value in ret. A flaw was found in the Linux kernel’s Xilinx DMA (Direct Memory Access) engine. The xdma driver’s regmap initialization incorrectly handled errors, specifically when the devm_regmap_init_mmio function returned an error pointer instead of a null value. This improper error handling could potentially lead to system instability or resource exhaustion under specific error conditions.Details
