Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Null pointer dereference (CVE-ID: CVE-2019-16232)
The vulnerability allows a local privileged user to perform a denial of service (DoS) attack.
drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.
2) 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).
3) 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).
4) 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.
5) 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).
6) Information disclosure (CVE-ID: CVE-2019-18660)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to absent protection in Linux kernel on powerpc against the Spectre-RSB, related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. A local user can gain unauthorized access to sensitive information on the system.
