ntfs: ->d_compare() must not block_CVE-2026-43245

    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: ->d_compare() must not block\n\n... so don't use __getname() there.  Switch it (and ntfs_d_hash(), while\nwe are at it) to kmalloc(PATH_MAX, GFP_NOWAIT).  Yes, ntfs_d_hash()\nalmost certainly can do with smaller allocations, but let ntfs folks\ndeal with that - keep the allocation size as-is for now.\n\nStop abusing names_cachep in ntfs, period - various uses of that thing\nin there have nothing to do with pathnames; just use k[mz]alloc() and\nbe done with that.  For now let's keep sizes as-in, but AFAICS none of\nthe users actually want PATH_MAX.",
