CVE-2018-19824 [HIGH] CWE-416 CVE-2018-19824: In the Linux kernel through 4.19.6, a local user could exploit a use-after-free in the ALSA driver b In the Linux kernel through 4.19.6, a local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c.

CVE-2018-1100 [HIGH] CWE-120 CVE-2018-1100: zsh through version 5.4.2 is vulnerable to a stack-based buffer overflow in the utils.c:checkmailpat zsh through version 5.4.2 is vulnerable to a stack-based buffer overflow in the utils.c:checkmailpath function. A local attacker could exploit this to execute arbitrary code in the context of another user.

CVE-2018-16847 [HIGH] CWE-787 CVE-2018-16847: An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It co An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in nvme device. A guest user/process could use this flaw to crash the QEMU process resulting in DoS or potentially run arbitrary code with privileges of the QEMU process.

CVE-2018-10902 [HIGH] CWE-416 CVE-2018-10902: It was found that the raw midi kernel driver does not protect against concurrent access which leads It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file.
