  "details": "In the Linux kernel, the following vulnerability has been resolved:  scsi: qla2xxx: Fix FCE trace use-after-free during firmware dump  qla2x00_free_fce_trace() freed and cleared ha-\u003efce while holding only fce_mutex. The firmware-dump consumers qla27xx_fwdt_entry_t264() and qla25xx_copy_fce() read ha-\u003efce (NULL check followed by a copy of the buffer) under hardware_lock and never take fce_mutex. A debugfs FCE disable could therefore free the DMA buffer between a dump's NULL check and its copy, resulting in a use-after-free.  Unpublish ha-\u003efce under hardware_lock, then release the lock and free the DMA buffer (dma_free_coherent() may sleep). A concurrent dump either completes its check and copy with the buffer still valid, or observes ha-\u003efce == NULL and skips it.",
