Insight
Insight
ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access.(CVE-2018-7566) The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.(CVE-2018-10675) The Linux kernel has an undefined behavior when an argument of INT_MIN is passed to the kernel/signal.c:kill_something_info() function. A local attacker may be able to exploit this to cause a denial of service.(CVE-2018-10124) A an integer overflow vulnerability was discovered in the Linux kernel, from version 3.4 through 4.15, in the drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An attacker with access to the udldrmfb driver could exploit this to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space.(CVE-2018-8781) The code in the drivers/scsi/libsas/sas_scsi_host.c file in the Linux kernel allow a physically proximate attacker to cause a memory leak in the ATA command queue and, thus, denial of service by triggering certain failure conditions.(CVE-2018-10021) A flaw was found in the Linux kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.(CVE-2018-1068) A vulnerability was found in the Linux kernel's kernel/events/core.c:perf_cpu_time_max_percent_handler() function. Local privileged users could exploit this flaw to cause a denial of service due to integer overflow or possibly have unspecified other impact.(CVE-2017-18255) The kernel_wait4 function in kernel/exit.c in the Linux kernel, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value.(CVE-2018-10087) A null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in the Linux kernel allows a local user to cause a denial of service by a number of certain crafted system calls.(CVE-2018-1130) An address corruption flaw was discovered in the Linux kernel built with hardware breakpoint (CONFIG_HAVE_HW_BREAKPOINT) support. While modifying a h/w breakpoint via 'modify_user_hw_breakpoint' routine, an unprivileged user/process could use this flaw to crash the system kernel resulting in DoS OR to potentially escalate privileges on a the system.(CVE-2018-1000199)
