Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A NULL pointer dereference error occurs in the
f2fs submit page write() function when io->bio is NULL. This happens when other threads have added the fio to io->bio and submitted it before entering f2fs submit page write(). The error occurs at bio get(io->bio) when is end zone blkaddr(sbi, fio->new blkaddr) is true. The original code for determining zone end was moved from after "out:" to before "skip:" to ensure it is done for each fio.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
