By sending specially crafted ISDN packets, a + remote attacker could exploit this to crash the kernel. +Notes: + dannf> According to Marcel Holtmann, 2.4 and 2.6 < 2.6.13 are not vulnerable. + dannf> Indeed, in 2.4.27 & 2.6.8, init_timer() just sets timer->base to NULL, + dannf> so the memset() is sufficient to avoid this crash. + dannf> However, in 2.6.8 init_timer() also sets a magic number. add_timer() + dannf> will call __mod_timer(), which calls check_timer(), which will cause + dannf> the kernel to whine if this magic number is not set.
