"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wilc1000: fix dma_buffer leak on bus acquire failure\n\nwilc_wlan_firmware_download() allocates dma_buffer with kmalloc() at\nthe top of the function and uses a 'fail:' label to free it via\nkfree(dma_buffer) on error.\n\nAll later error paths correctly use 'goto fail' to route through this\ncleanup. However, the early failure path after the first acquire_bus()\ncall uses a bare 'return ret;', which leaks dma_buffer whenever the bus\nacquire fails.\n\nReplace the early return with goto fail so the existing cleanup path\nruns.\n\nFound via a custom Coccinelle semantic patch hunting for kmalloc'd\nlocals leaked on early-return error paths in driver firmware-download\ncode."
