  "description": "In the Linux kernel, the following vulnerability has been resolved:  dm-pcache: clamp the tail kset read to the segment data region  The tail-kset read in cache_replay(), the writeback worker and the GC worker bounds its length by PCACHE_SEG_SIZE - seg_off, the raw segment size rather than the data region. A tail near the segment end reads past the segment data into the following control area.  Clamp the read to cache_seg_remain(), the data region.",
