      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nieee802154: ca8210: fix cas_ctl leak on spi_async failure\n\nca8210_spi_transfer() allocates cas_ctl with kzalloc_obj(GFP_ATOMIC)\nand relies entirely on the SPI completion callback\nca8210_spi_transfer_complete() to free it.\n\nThe spi_async() API only invokes the completion callback on successful\nsubmission.  On failure it returns a negative error code without ever\nqueuing the callback, which leaves cas_ctl and its embedded spi_message\nand spi_transfer orphaned.  Every kfree(cas_ctl) in the driver is\ninside the completion callback, so there is no other reclamation path.\n\nca8210_spi_transfer() is called from ca8210_spi_exchange(), the\ninterrupt handler ca8210_interrupt_handler(), and from the retry path\ninside the completion callback itself.  The exchange and interrupt\nhandler paths loop on -EBUSY, so under sustained SPI bus contention\nevery retry iteration leaks a fresh cas_ctl (~600 bytes per\noccurrence).\n\nFix it by freeing cas_ctl on the spi_async() error path.  While here,\ncorrect the misleading error string: the function calls spi_async(),\nnot spi_sync().",
