Уязвимость функции vmacache_flush_all() ядра операционной системы Linux, позволяющая нарушителю повысить свои привилегии

Уязвимость функции cdrom_ioctl_drive_status() операционных систем Linux, позволяющая нарушителю получить несанкционированный доступ к защищаемой информации

Уязвимость функции __blk_drain_queue() в файле block/blk-core.c ядра операционной системы Linux, позволяющая нарушителю оказать воздействие на целостность данных, получить несанкционированный доступ к защищаемой информации, а также вызвать отказ в обслуживании

An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940.

An issue was discovered in the Linux kernel through 4.18.8. The vmacache_flush_all function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations.

An issue was discovered in the Linux kernel before 4.18.7. In create_qp_common in drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of stack memory to userspace.

An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an __blk_drain_queue() use-after-free because a certain error case is mishandled.

Уязвимость функции chap_server_compute_md5() реализации протокола ISCSI ядра операционных систем Linux, позволяющая нарушителю вызвать отказ в обслуживании или получить доступ к защищаемой информации

Уязвимость функции irda_setsockopt ядра операционной системы Linux, позволяющая нарушителю вызывать отказ в обслуживании

Уязвимость драйвера drivers/staging/irda/net/af_irda.c ядра операционной системы Linux, позволяющая нарушителю вызвать отказ в обслуживании

A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.

Memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket.

The irda_setsockopt function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket.
