CVE-2026-64485

High

In the Linux kernel, the following vulnerability has been resolved: ALSA: compress: Fix task creation error unwind snd_compr_task_new() allocates the driver task before validating the returned DMA buffers and reserving file descriptors. When either of those later steps fails, the core frees its task wrapper and DMA-buffer references without calling the driver's task_free() callback. Any driver resources allocated by task_create() are therefore leaked. The dual-fd allocation path also jumps to cleanup without storing the negative get_unused_fd_flags() result in retval. Since retval still contains the successful task_create() return value, TASK_CREATE can incorrectly report success although the task was discarded. Preserve the fd allocation errors and call task_free() when failure occurs after a successful task_create() callback.
