- Summary
- fs/netfs/read_collect: add to next->prev_donated
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
fs/netfs/readcollect: add to next->prevdonated
If multiple subrequests donate data to the same "next" request (depending on the subrequest completion order), each of them would overwrite the
prev_donatedfield, causing data corruption and a BUG() crash ("Can't donate prior to front"). - References
