Subject: [PATCH] 2.4.13pre3aa1: expand_fdset() may use invalid pointer
Date: Wed, 17 Oct 2001 11:32:45 -0700 [thread overview]
Message-ID: <20011017113245.A3849@perlsupport.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 318 bytes --]
In 2.4.13pre3aa1, expand_fdset() in fs/file.c has a couple of
execution paths that call kfree() on a pointer that hasn't yet been
initialized. A minimal patch is attached.
