  "details": "In the Linux kernel, the following vulnerability has been resolved:  dm era: fix out-of-bounds memory access for non-zero start sector  dm-era tracks writes in target-relative blocks, but era_map() calculates the writeset block before applying the target offset.  Tables with a non-zero start sector can therefore pass an absolute mapped-device block to metadata_current_marked().  If the absolute block is beyond the current writeset size, writeset_marked() tests past the end of the in-core bitset.  KASAN reports this as a vmalloc-out-of-bounds access.  Apply the target offset before calculating the era block so writeset lookups use the target-relative block number.",
