privilege escalation, denial of service or information leaks.\n\nCVE-2019-14821\n\nMatt Delco reported a race condition in KVM's coalesced MMIO facility, which could lead to out-of-bounds access in the kernel. A local attacker permitted to access /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-14835\n\nPeter Pi of Tencent Blade Team discovered a missing bounds check in vhost_net, the network back-end driver for KVM hosts, leading to a buffer overflow when the host begins live migration of a VM. An attacker in control of a VM could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation on the host.\n\nCVE-2019-15117\n\nHui Peng and Mathias Payer reported a missing bounds check in the usb-audio driver's descriptor parsing code, leading to a buffer over-read. An attacker able to add USB devices could possibly use this to cause a denial of service (crash).\n\nCVE-2019-15118\n\nHui Peng and Mathias Payer reported unbounded recursion in the usb-audio driver's descriptor parsing code, leading to a stack overflow.

"2023-02-05T15:16:48", "description": "Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.\n\nCVE-2016-10905\n\nA race condition was discovered in the GFS2 file-system implementation, which could lead to a use-after-free. On a system using GFS2, a local attacker could use this for denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2018-20976\n\nIt was discovered that the XFS file-system implementation did not correctly handle some mount failure conditions, which could lead to a use-after-free. The security impact of this is unclear.\n\nCVE-2018-21008\n\nIt was discovered that the rsi wifi driver did not correctly handle some failure conditions, which could lead to a use-after- free. The security impact of this is unclear.\n\nCVE-2019-0136\n\nIt was discovered that the wifi soft-MAC implementation (mac80211) did not properly authenticate Tunneled Direct Link Setup (TDLS) messages.\nA nearby attacker could use this for denial of service (loss of wifi connectivity).\n\nCVE-2019-9506\n\nDaniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered a weakness in the Bluetooth pairing protocols, dubbed the 'KNOB attack'. An attacker that is nearby during pairing could use this to weaken the encryption used between the paired devices, and then to eavesdrop on and/or spoof communication between them.\n\nThis update mitigates the attack by requiring a minimum encryption key length of 56 bits.\n\nCVE-2019-14814, CVE-2019-14815, CVE-2019-14816\n\nMultiple bugs were discovered in the mwifiex wifi driver, which could lead to heap buffer overflows. A local user permitted to configure a device handled by this driver could probably use this for privilege escalation.\n\nCVE-2019-14821\n\nMatt Delco reported a race condition in KVM's coalesced MMIO facility, which could lead to out-of-bounds access in the kernel. A local attacker permitted to access /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-14835\n\nPeter Pi of Tencent Blade Team discovered a missing bounds check in vhost_net, the network back-end driver for KVM hosts, leading to a buffer overflow when the host begins live migration of a VM. An attacker in control of a VM could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation on the host.\n\nCVE-2019-15117\n\nHui Peng and Mathias Payer reported a missing bounds check in the usb-audio driver's descriptor parsing code, leading to a buffer over-read. An attacker able to add USB devices could possibly use this to cause a denial of service (crash).\n\nCVE-2019-15118\n\nHui Peng and Mathias Payer reported unbounded recursion in the usb-audio driver's descriptor parsing code, leading to a stack overflow. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-15211\n\nThe syzkaller tool found a bug in the radio-raremono driver that could lead to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-15212\n\nThe syzkaller tool found that the rio500 driver does not work correctly if more than one device is bound to it. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-15215\n\nThe syzkaller tool found a bug in the cpia2_usb driver that leads to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-15218\n\nThe syzkaller tool found that the smsusb driver did not validate that USB devices have the expected endpoints, potentially leading to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).\n\nCVE-2019-15219\n\nThe syzkaller tool found that a device initialisation error in the sisusbvga driver could lead to a NULL pointer dereference.

On a system\nusing GFS2, a local attacker could use this for denial of service\n(memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2018-20976\n\nIt was discovered that the XFS file-system implementation did not\ncorrectly handle some mount failure conditions, which could lead to a\nuse-after-free. The security impact of this is unclear.\n\nCVE-2018-21008\n\nIt was discovered that the rsi wifi driver did not correctly handle\nsome failure conditions, which could lead to a use-after- free. The\nsecurity impact of this is unclear.\n\nCVE-2019-0136\n\nIt was discovered that the wifi soft-MAC implementation (mac80211) did\nnot properly authenticate Tunneled Direct Link Setup (TDLS) messages.\nA nearby attacker could use this for denial of service (loss of wifi\nconnectivity).\n\nCVE-2019-9506\n\nDaniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen\ndiscovered a weakness in the Bluetooth pairing protocols, dubbed the\n'KNOB attack'. An attacker that is nearby during pairing could use\nthis to weaken the encryption used between the paired devices, and\nthen to eavesdrop on and/or spoof communication between them.\n\nThis update mitigates the attack by requiring a minimum\nencryption key length of 56 bits.\n\nCVE-2019-14814, CVE-2019-14815, CVE-2019-14816\n\nMultiple bugs were discovered in the mwifiex wifi driver, which could\nlead to heap buffer overflows. A local user permitted to configure a\ndevice handled by this driver could probably use this for privilege\nescalation.\n\nCVE-2019-14821\n\nMatt Delco reported a race condition in KVM's coalesced MMIO facility,\nwhich could lead to out-of-bounds access in the kernel. A local\nattacker permitted to access /dev/kvm could use this to cause a denial\nof service (memory corruption or crash) or possibly for privilege\nescalation.\n\nCVE-2019-14835\n\nPeter Pi of Tencent Blade Team discovered a missing bounds check in\nvhost_net, the network back-end driver for KVM hosts, leading to a\nbuffer overflow when the host begins live migration of a VM. An\nattacker in control of a VM could use this to cause a denial of\nservice (memory corruption or crash) or possibly for privilege\nescalation on the host.\n\nCVE-2019-15117\n\nHui Peng and Mathias Payer reported a missing bounds check in the\nusb-audio driver's descriptor parsing code, leading to a buffer\nover-read. An attacker able to add USB devices could possibly use this\nto cause a denial of service (crash).\n\nCVE-2019-15118\n\nHui Peng and Mathias Payer reported unbounded recursion in the\nusb-audio driver's descriptor parsing code, leading to a stack\noverflow. An attacker able to add USB devices could use this to cause\na denial of service (memory corruption or crash) or possibly for\nprivilege escalation.\n\nCVE-2019-15211\n\nThe syzkaller tool found a bug in the radio-raremono driver that could\nlead to a use-after-free. An attacker able to add and remove USB\ndevices could use this to cause a denial of service (memory corruption\nor crash) or possibly for privilege escalation.\n\nCVE-2019-15212\n\nThe syzkaller tool found that the rio500 driver does not work\ncorrectly if more than one device is bound to it. An attacker able to\nadd USB devices could use this to cause a denial of service (memory\ncorruption or crash) or possibly for privilege escalation.\n\nCVE-2019-15215\n\nThe syzkaller tool found a bug in the cpia2_usb driver that leads to a\nuse-after-free. An attacker able to add and remove USB devices could\nuse this to cause a denial of service (memory corruption or crash) or\npossibly for privilege escalation.\n\nCVE-2019-15218\n\nThe syzkaller tool found that the smsusb driver did not validate that\nUSB devices have the expected endpoints, potentially leading to a NULL pointer dereference. An attacker able to add USB devices could use\nthis to cause a denial of service (BUG/oops).\n\nCVE-2019-15219\n\nThe syzkaller tool found that a device initialisation error in the\nsisusbvga driver could lead to a NULL pointer dereference. An attacker\nable to add USB devices could use this to cause a denial of service\n(BUG/oops).\n\nCVE-2019-15220\n\nThe syzkaller tool found a race condition in the p54usb driver which\ncould lead to a use-after-free. An attacker able to add and remove USB\ndevices could use this to cause a denial of service (memory corruption\nor crash) or possibly for privilege escalation.\n\nCVE-2019-15221\n\nThe syzkaller tool found that the line6 driver did not validate USB\ndevices' maximum packet sizes, which could lead to a heap buffer\noverrun. An attacker able to add USB devices could use this to cause a\ndenial of service (memory corruption or crash) or possibly for\nprivilege escalation.\n\nCVE-2019-15292\n\nThe Hulk Robot tool found missing error checks in the Appletalk\nprotocol implementation, which could lead to a use-after-free. The\nsecurity impact of this is unclear.\n\nCVE-2019-15807\n\nJian Luo reported that the Serial Attached SCSI library (libsas) did\nnot correctly handle failure to discover devices beyond a SAS\nexpander. This could lead to a resource leak and crash (BUG). The\nsecurity impact of this is unclear.\n\nCVE-2019-15917\n\nThe syzkaller tool found a race condition in code supporting\nUART-attached Bluetooth adapters, which could lead to a use-\nafter-free. A local user with access to a pty device or other suitable\ntty device could use this to cause a denial of service (memory\ncorruption or crash) or possibly for privilege escalation.\n\nCVE-2019-15926\n\nIt was found that the ath6kl wifi driver did not consistently validate\ntraffic class numbers in received control packets, leading to\nout-of-bounds memory accesses.

This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).\n\nCVE-2019-15291: Fixed a NULL pointer dereference issue that could be caused by a malicious USB device (bnc#11465).\n\nCVE-2019-15807: Fixed a memory leak in the SCSI module that could be abused to cause denial of service (bnc#1148938).\n\nCVE-2019-14821: An out-of-bounds access issue was fixed in the kernel's KVM hypervisor. 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).\n\nCVE-2019-15505: An out-of-bounds issue had been fixed that could be caused by crafted USB device traffic (bnc#1147122).\n\nCVE-2017-18595: A double free in allocate_trace_buffer was fixed (bnc#1149555).\n\nCVE-2019-14835: A buffer overflow flaw was found in the kernel's vhost functionality that translates virtqueue buffers to IOVs. A privileged guest user able to pass descriptors with invalid length to the host could use this flaw to increase their privileges on the host (bnc#1150112).\n\nCVE-2019-15216: A NULL pointer dereference was fixed that could be malicious USB device (bnc#1146361).\n\nCVE-2019-9456: An out-of-bounds write in the USB monitor driver has been fixed.

That issue allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146512).\n\nCVE-2019-14815: A missing length check while parsing WMM IEs was fixed (bsc#1146512, bsc#1146514, bsc#1146516).\n\nCVE-2019-14816: A heap-based buffer overflow in the marvell wifi chip driver was fixed. Local users would have abused this issue to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146516).\n\nCVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific socket option, an attacker could control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)\n\nCVE-2019-9506: The Bluetooth BR/EDR specification used to permit 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 inject arbitrary ciphertext without the victim noticing (bnc#1137865).\n\nCVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath was fixed (bnc#1146378).\n\nCVE-2019-15290: A NULL pointer dereference in ath6kl_usb_alloc_urb_from_pipe was fixed (bsc#1146378).\n\nCVE-2019-15212: A double-free issue was fixed in drivers/usb driver (bnc#1146391).\n\nCVE-2016-10906: A use-after-free issue was fixed in drivers/net/ethernet/arc (bnc#1146584).\n\nCVE-2019-15217: A a NULL pointer dereference issue caused by a malicious USB device was fixed in the drivers/media/usb/zr364xx driver (bnc#1146519).\n\nCVE-2019-15218: A NULL pointer dereference caused by a malicious USB device was fixed in the drivers/media/usb/siano driver (bnc#1146413).\n\nCVE-2019-15215: A use-after-free issue caused by a malicious USB device was fixed in the drivers/media/usb/cpia2 driver (bnc#1146425).\n\nCVE-2018-20976: A use-after-free issue was fixed in the fs/xfs driver (bnc#1146285).\n\nCVE-2017-18551: An out-of-bounds write was fixed in the drivers/i2c driver (bnc#1146163).\n\nCVE-2019-10207: Add checks for missing tty operations to prevent unprivileged user to execute 0x0 address (bsc#1142857 bsc#1123959)\n\nCVE-2019-15118: ALSA: usb-audio: Fix a stack-based buffer overflow bug in check_input_term leading to kernel stack exhaustion (bsc#1145922).\n\nThe update package also includes non-security fixes.

"2023-02-26T15:29:15", "description": "The SUSE Linux Enterprise 12 SP4 for Azure kernel was updated to receive various security and bugfixes.\n\nThe following security bugs were fixed :\n\nCVE-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).\n\nCVE-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).\n\nCVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).\n\nCVE-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.\nThis allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).\n\nCVE-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. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could have used this flaw to increase their privileges on the host (bnc#1150112).\n\nCVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).\n\nCVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).\n\nCVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).\n\nCVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, 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 was misused in arch/powerpc/kernel/process.c (bnc#1149713).\n\nCVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have 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).\n\nCVE-2019-15920: SMB2_read in fs/cifs/smb2pdu.c had a use-after-free.\n(bnc#1149626).\n\nCVE-2019-15921: There was a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c (bnc#1149602).\n\nCVE-2018-21008: A use-after-free could have been caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).\n\nCVE-2019-15919: SMB2_write in fs/cifs/smb2pdu.c had a use-after-free (bnc#1149552).\n\nCVE-2019-15917: There was a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c (bnc#1149539).\n\nCVE-2019-15926: An out-of-bounds access existed in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c (bnc#1149527).\n\nCVE-2019-15927: An out-of-bounds access existed in the function build_audio_procunit in the file sound/usb/mixer.c (bnc#1149522).\n\nCVE-2019-15902: Misuse of the upstream 'x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()' commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).\n\nCVE-2019-15666: There was an out-of-bounds array access in\n__xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandled directory validation (bnc#1148394).\n\nCVE-2019-15219: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver (bnc#1146524).\n\nCVE-2019-14814: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146512).\n\nCVE-2019-14815: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code.\n(bsc#1146514)\n\nCVE-2019-14816: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146516).\n\nCVE-2019-15220: There was a use-after-free caused by a malicious USB device in the drivers/net/wireless/intersil/p54/p54usb.c driver (bnc#1146526).\n\nCVE-2019-15538: An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS (bnc#1148093).\n\nCVE-2019-15290: There was a NULL pointer dereference caused by a malicious USB device in the ath6kl_usb_alloc_urb_from_pipe function (bsc#1146543).\n\nCVE-2019-15098: drivers/net/wireless/ath/ath6kl/usb.c had a NULL pointer dereference via an incomplete address in an endpoint descriptor (bnc#1146378).\n\nCVE-2019-15239: An incorrect backport of a certain net/ipv4/tcp_output.c fix allowed a local attacker to trigger multiple use-after-free conditions. This could result in a kernel crash, or potentially in privilege escalation. (bsc#1146589)\n\nCVE-2019-15212: There was a double-free caused by a malicious USB device in the drivers/usb/misc/rio500.c driver (bnc#1146391).\n\nCVE-2019-15292: There was a use-after-free in atalk_proc_exit, related to net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and net/appletalk/sysctl_net_atalk.c (bnc#1146678).\n\nCVE-2019-15217: There was a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver (bnc#1146547).\n\nCVE-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).\n\nCVE-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).\n\nCVE-2019-15221: There was a NULL pointer dereference caused by a malicious USB device in the sound/usb/line6/pcm.c driver (bnc#1146529).\n\nCVE-2019-15222: There was a NULL pointer dereference caused by a malicious USB device in the sound/usb/helper.c (motu_microbookii) driver (bnc#1146531).\n\nCVE-2019-15218: There was a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver (bnc#1146413).\n\nCVE-2019-15215: There was a use-after-free caused by a malicious USB device in the drivers/media/usb/cpia2/cpia2_usb.c driver (bnc#1146425).\n\nCVE-2019-15090: An issue was discovered in drivers/scsi/qedi/qedi_dbg.c in the qedi_dbg_* family of functions, there is an out-of-bounds read (bnc#1146399).\n\nCVE-2018-20976: An issue was discovered in fs/xfs/xfs_super.c. A use after free exists, related to xfs_fs_fill_super failure (bnc#1146285).\n\nCVE-2017-18551: An issue was discovered in drivers/i2c/i2c-core-smbus.c. There was an out of bounds write in the function i2c_smbus_xfer_emulated (bnc#1146163).\n\nCVE-2019-15118: check_input_term in sound/usb/mixer.c mishandled recursion, leading to kernel stack exhaustion (bnc#1145922).\n\nCVE-2019-15117: parse_audio_mixer_unit in sound/usb/mixer.c mishandled a short descriptor, leading to out-of-bounds memory access (bnc#1145920).\n\nCVE-2019-10207: Fix a NULL pointer dereference in hci_uart bluetooth driver (bsc#1142857 bsc#1123959).\n\nThe update package also includes non-security fixes.

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).\n\n - 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,
