Subject: [PATCH] eCryptfs: Remove buggy and unnecessary write in file name
|
||||
decode routine
|
||||
|
||||
Dmitry Chernenkov used KASAN to discover that eCryptfs writes past the
|
||||
end of the allocated buffer during encrypted filename decoding. This
|
||||
fix corrects the issue by getting rid of the unnecessary 0 write when
|
||||
the current bit offset is 2.
