  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: compress: Fix task creation error unwind\n\nsnd_compr_task_new() allocates the driver task before validating the\nreturned DMA buffers and reserving file descriptors. When either of\nthose later steps fails, the core frees its task wrapper and DMA-buffer\nreferences without calling the driver's task_free() callback. Any\ndriver resources allocated by task_create() are therefore leaked.\n\nThe dual-fd allocation path also jumps to cleanup without storing the\nnegative get_unused_fd_flags() result in retval. Since retval still\ncontains the successful task_create() return value, TASK_CREATE can\nincorrectly report success although the task was discarded.\n\nPreserve the fd allocation errors and call task_free() when failure\noccurs after a successful task_create() callback.",
