CVE-2018-6554

A memory leak in the irda_bind function in the irda subsystem was discovered. A local user can take advantage of this flaw to cause a denial of service (memory consumption).

CVE-2018-6555

A flaw was discovered in the irda_setsockopt function in the irda subsystem, allowing a local user to cause a denial of service (use-after-free and system crash).

CVE-2018-7755

Brian Belleville discovered a flaw in the fd_locked_ioctl function in the floppy driver in the Linux kernel. The floppy driver copies a kernel pointer to user memory in response to the FDGETPRM ioctl. A local user with access to a floppy drive device can take advantage of this flaw to discover the location kernel code and data.

CVE-2018-9363

It was discovered that the Bluetooth HIDP implementation did not correctly check the length of received report messages. A paired HIDP device could use this to cause a buffer overflow, leading to denial of service (memory corruption or crash) or potentially remote code execution.

CVE-2018-9516

It was discovered that the HID events interface in debugfs did not correctly limit the length of copies to user buffers. A local user with access to these files could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. However, by default debugfs is only accessible by the root user.

CVE-2018-10902

It was discovered that the rawmidi kernel driver does not protect against concurrent access which leads to a double-realloc (double free) flaw. A local attacker can take advantage of this issue for privilege escalation.

CVE-2018-10938

Yves Younan from Cisco reported that the Cipso IPv4 module did not correctly check the length of IPv4 options. On custom kernels with CONFIG_NETLABEL enabled, a remote attacker could use this to cause a denial of service (hang).

CVE-2018-13099

Wen Xu from SSLab at Gatech reported a use-after-free bug in the F2FS implementation. An attacker able to mount a crafted F2FS volume could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.

CVE-2018-14609

Wen Xu from SSLab at Gatech reported a potential null pointer dereference in the F2FS implementation. An attacker able to mount arbitrary F2FS volumes could use this to cause a denial of service (crash).

CVE-2018-14617

Wen Xu from SSLab at Gatech reported a potential null pointer dereference in the HFS+ implementation. An attacker able to mount arbitrary HFS+ volumes could use this to cause a denial of service (crash).

CVE-2018-14633

Vincent Pelletier discovered a stack-based buffer overflow flaw in the chap_server_compute_md5() function in the iSCSI target code. An unauthenticated remote attacker can take advantage of this flaw to cause ... [Please see the references for more information on the vulnerabilities]");
