CVE-2026-43245

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ntfs: -&gt;d_compare() must not block<br /> <br /> ... so don&amp;#39;t use __getname() there. Switch it (and ntfs_d_hash(), while<br /> we are at it) to kmalloc(PATH_MAX, GFP_NOWAIT). Yes, ntfs_d_hash()<br /> almost certainly can do with smaller allocations, but let ntfs folks<br /> deal with that - keep the allocation size as-is for now.<br /> <br /> Stop abusing names_cachep in ntfs, period - various uses of that thing<br /> in there have nothing to do with pathnames; just use k[mz]alloc() and<br /> be done with that. For now let&amp;#39;s keep sizes as-in, but AFAICS none of<br /> the users actually want PATH_MAX.
