Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the hfs module, specifically in the
hfs asc2mac() function. A Syzbot report identified an out-of-bounds write issue. This occurs when the input length (in->len) exceeds the maximum HFS filename length (HFS NAMELEN, which is 31). The issue arises because the destination buffer (dst) reaches its boundary while the source length (srclen) remains greater than zero, leading to a write beyond the allocated memory. The hfs asc2mac() function is involved in converting filenames. The hfs cat build key() and hfs lookup() functions are also implicated in the call trace.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
