Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Memory leak (CVE-ID: CVE-2019-18809)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the "af9005_identify_state()" function in drivers/media/usb/dvb-usb/af9005.c in the Linux kernel through 5.3.9 allows a local user to cause a denial of service (memory consumption).


2) Memory leak (CVE-ID: CVE-2019-18812)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the "sof_dfsentry_write()" function in sound/soc/sof/debug.c in the Linux kernel through 5.3.9 allows a local user to cause a denial of service (memory consumption).


3) Memory leak (CVE-ID: CVE-2019-18811)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the "sof_set_get_large_ctrl_data()" function in sound/soc/sof/ipc.c in the Linux kernel through 5.3.9 allows a local user to cause a denial of service (memory consumption) by triggering "sof_get_ctrl_copy_params()" failures.


4) Memory leak (CVE-ID: CVE-2019-18813)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the "dwc3_pci_probe()" function in "drivers/usb/dwc3/dwc3-pci.c" in the Linux kernel through 5.3.9 allows local user to cause a denial of service (memory consumption) by triggering "platform_device_add_properties()" failures.


5) Use-after-free (CVE-ID: CVE-2019-18814)

The vulnerability allows a local user to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when "aa_label_parse()" fails in "aa_audit_rule_init()" in security/apparmor/audit.c. A local user can execute arbitrary code on the target system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


6) Memory leak (CVE-ID: CVE-2019-18808)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the "ccp_run_sha_cmd()" function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows a local user to cause a denial of service (memory consumption).
