The sctpprocessparam function in net/sctp/smmakechunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service NULL pointer dereference and system crash via a malformed INIT chunk. CVE-2014-7841 The pivotroot...

CVE-2014-9090

The dodoublefault function in arch/x86/kernel/traps.c in the Linux kernel through 3.17.4 does not properly handle faults associated with the Stack Segment SS segment register, which allows local users to cause a denial of service panic via a modifyldt system call, as demonstrated by sigreturn32 i...

CVE-2014-9090

CVE-2014-9090 affects the Linux kernel up to 3.17.4, where do_double_fault in arch/x86/kernel/traps.c mishandles SS fault conditions, allowing local users to cause a denial of service (panic) via modify_ldt (demonstrated by sigreturn_32 in linux-clock-tests). The issue was addressed by a patch li...
