CVE-2019-15214

An issue was discovered in the Linux kernel before 5.0.10. There is a use-after-free in the sound subsystem because card disconnection causes certain data structures to be deleted too early. This is related to sound/core/init.c and sound/core/info.c.

The openSUSE Leap 15.0 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2017-18551: There was an out of bounds write in the function i2c_smbus_xfer_emulated (bnc#1146163).
• CVE-2018-20976: A use after free exists, related to xfs_fs_fill_super failure (bnc#1146285).
• CVE-2018-21008: A use-after-free can be caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).
• CVE-2019-14814: A heap overflow in mwifiex_set_uap_rates() function of Marvell was fixed. (bnc#1146512).
• CVE-2019-14815: A heap overflow in mwifiex_set_wmm_params() function of Marvell Wifi Driver was fixed. (bnc#1146514).
• CVE-2019-14816: A heap overflow in mwifiex_update_vs_ie() function of Marvell Wifi Driver was fixed. (bnc#1146516).
• CVE-2019-14835: A vhost/vhost_net kernel buffer overflow could lead to guest to host kernel escape during live migration (bnc#1150112).
• CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).
• CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c (bnc#1149713).
• CVE-2019-15090: In the qedi_dbg_* family of functions, there was an out-of-bounds read (bnc#1146399).
• CVE-2019-15098: drivers/net/wireless/ath/ath6kl/usb.c had a NULL pointer dereference via an incomplete address in an endpoint descriptor (bnc#1146378).
• CVE-2019-15117: parse_audio_mixer_unit in sound/usb/mixer.c in the Linux kernel mishandled a short descriptor, leading to out-of-bounds memory access (bnc#1145920).
• CVE-2019-15118: check_input_term in sound/usb/mixer.c in the Linux kernel mishandled recursion, leading to kernel stack exhaustion (bnc#1145922).
• CVE-2019-15211: There was a use-after-free caused by a malicious USB device in the drivers/media/v4l2-core/v4l2-dev.c driver because drivers/media/radio/radio-raremono.c did not properly allocate memory (bnc#1146519).
• CVE-2019-15212: There was a double-free caused by a malicious USB device in the drivers/usb/misc/rio500.c driver (bnc#1146391).
• CVE-2019-15214: There was a use-after-free in the sound subsystem because card disconnection causes certain data structures to be deleted too early. This is related to sound/core/init.c and sound/core/info.c (bnc#1146550).

The SUSE Linux Enterprise 12 SP4 for Azure kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2019-15291: There was a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540).
• CVE-2019-14821: An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350).
• CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).
• CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).
• CVE-2019-14835: A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration.
