Description:
Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service) and potentially gain escalated privileges, and by malicious people to cause a DoS.
1) A vulnerability is caused due to the incorrect initialisation of the proto_ops structure for certain protocols (e.g. PF_APPLETALK, PF_IPX, PF_IRDA, PF_X25, PF_AX25 families, PF_BLUETOOTH, PF_IUCV, PF_INET6 (with IPPROTO_SCTP), PF_PPPOX, and PF_ISDN), which can be exploited to cause a NULL pointer dereference when triggering the "sock_sendpage()" function for an incorrectly initialised socket.
2) A NULL pointer dereference exists within the "cmp_ies()" function in net/wireless/scan.c. This can be exploited to crash a vulnerable system by tricking it into scanning and processing specially crafted SSID IEs.
3) A NULL pointer dereference exists within the "load_flat_shared_library()" function in fs/binfmt_flat.c, which can be exploited to cause a crash and potentially execute arbitrary code with root privileges.
