Description
A flaw was found in the Linux kernel. The ieee802154: ca8210 driver fails to free allocated memory (cas_ctl) when the spi_async() operation encounters an error. Under sustained Serial Peripheral Interface (SPI) bus contention, this can lead to repeated memory leaks. This continuous resource exhaustion may result in a Denial of Service (DoS) for the system.
