In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring.

Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that a heap-based buffer overflow existed in the Marvell
WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-14895, CVE-2019-14901)
It was discovered that a heap-based buffer overflow existed in the Marvell

CVE-2019-19807 [HIGH] CWE-416 kernel: use-after-free in sound/core/timer.c
kernel: use-after-free in sound/core/timer.c
In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring.
A memory flaw was found in the ALSA subsystem of the Linux kernel. The struct snd_timer_instance function fails the timer->max_instances check leading to an invalid address. This could lead to a use-after-free vulnerability.
Statement: This issue affected Linux kernel versions as shipped with Red Hat Enterprise Linux 8 starting with RHEL-8.1.0, that is Red Hat Enterprise Linux 8.1 GA kernel version.
