  "details": "In the Linux kernel, the following vulnerability has been resolved:  zram: fix use-after-free in zram_bvec_write_partial()  zram_read_page() picks the sync or async backing device read path based on whether the parent bio is NULL.  zram_bvec_write_partial() passes its parent bio down, so for ZRAM_WB slots the read is dispatched asynchronously and zram_read_page() returns 0 while the bio is still in flight.  The caller then runs memcpy_from_bvec(), zram_write_page() and __free_page() on the buffer, leaving the async read to write into a freed page.  zram_bvec_read_partial() was switched to NULL in commit 4e3c87b9421d (\"zram: fix synchronous reads\") for the same reason; the write_partial counterpart was missed.",
