## Description
Al Viro discovered that the Linux kernel for s390x systems did not properly perform page table upgrades for kernel sections that use secondary address mode. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2020-11884)
It was discovered that the Intel Wi-Fi driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16234)
Tristan Madani discovered that the block I/O tracing implementation in the Linux kernel contained a race condition. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-19768)
It was discovered that the vhost net driver in the Linux kernel contained a stack buffer overflow. A local attacker with the ability to perform ioctl() calls on /dev/vhost-net could use this to cause a denial of service (system crash). (CVE-2020-10942)
It was discovered that the OV51x USB Camera device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-11608)
It was discovered that the STV06XX USB Camera device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-11609)
It was discovered that the Xirlink C-It USB Camera device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-11668)
It was discovered that the virtual terminal implementation in the Linux kernel contained a race condition. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2020-8648)
Jordy Zomer discovered that the floppy driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-9383)

A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.(CVE-2020-12826)\n\n - gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel through 5.6.13 relies on kstrdup without considering the possibility of an internal '\\0' value, which allows attackers to trigger an out-of-bounds read, aka CID-15753588bcd4.(CVE-2020-13143)\n\n - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040.(CVE-2020-12770)\n\n - An issue was found in Linux kernel before 5.5.4.\n mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy, aka CID-3a9b153c5591.(CVE-2020-12654)\n\n - An issue was found in Linux kernel before 5.5.4.

Reason: This candidate is a\n duplicate of CVE-2020-12826. Notes: All CVE users\n should reference CVE-2020-12826 instead of this\n candidate. All references and descriptions in this\n candidate have been removed to prevent accidental\n usage.(CVE-2020-10741)\n\n - A signal access-control issue was discovered in the\n Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32\n bits, an integer overflow can interfere with a\n do_notify_parent protection mechanism. A child process\n can send an arbitrary signal to a parent process in a\n different security domain. Exploitation limitations\n include the amount of elapsed time before an integer\n overflow occurs, and the lack of scenarios where\n signals to a parent process present a substantial\n operational threat.(CVE-2020-12826)\n\n - gadget_dev_desc_UDC_store in\n drivers/usb/gadget/configfs.c in the Linux kernel\n through 5.6.13 relies on kstrdup without considering\n the possibility of an internal '\\0' value, which allows\n attackers to trigger an out-of-bounds read, aka\n CID-15753588bcd4.(CVE-2020-13143)\n\n - An issue was discovered in the Linux kernel through\n 5.6.11. sg_write lacks an sg_remove_request call in a\n certain failure case, aka\n CID-83c6f2390040.(CVE-2020-12770)\n\n - An issue was found in Linux kernel before 5.5.4.\n mwifiex_ret_wmm_get_status() in\n drivers/net/wireless/marvell/mwifiex/wmm.c allows a\n remote AP to trigger a heap-based buffer overflow\n because of an incorrect memcpy, aka\n CID-3a9b153c5591.(CVE-2020-12654)\n\n - An issue was found in Linux kernel before 5.5.4. The\n mwifiex_cmd_append_vsie_tlv() function in\n drivers/net/wireless/marvell/mwifiex/scan.c allows\n local users to gain privileges or cause a denial of\n service because of an incorrect memcpy and buffer\n overflow, aka CID-b70261a288ea.(CVE-2020-12653)\n\n - usb_sg_cancel in drivers/usb/core/message.c in the\n Linux kernel before 5.6.8 has a use-after-free because\n a transfer occurs without a reference, aka\n CID-056ad39ee925.(CVE-2020-12464)\n\n - The __mptctl_ioctl function in\n drivers/message/fusion/mptctl.c in the Linux kernel\n before 5.4.14 allows local users to hold an incorrect\n lock during the ioctl operation and trigger a race\n condition, i.e., a 'double fetch' vulnerability, aka\n CID-28d76df18f0a. NOTE: the vendor states 'The security\n impact of this bug is not as bad as it could have been\n because these operations are all privileged and root\n already has enormous destructive\n power.'(CVE-2020-12652)\n\n - In the Linux kernel before 5.6.1,\n drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink\n camera USB driver) mishandles invalid descriptors, aka\n CID-a246b4d54770.(CVE-2020-11668)\n\n - An issue was discovered in the stv06xx subsystem in the\n Linux kernel before 5.6.1.\n drivers/media/usb/gspca/stv06xx/stv06xx.c and\n drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c\n mishandle invalid descriptors, as demonstrated by a\n NULL pointer dereference, aka\n CID-485b06aadb93.(CVE-2020-11609)\n\n - An issue was discovered in the Linux kernel before\n 5.6.1. drivers/media/usb/gspca/ov519.c allows NULL\n pointer dereferences in ov511_mode_init_regs and\n ov518_mode_init_regs when there are zero endpoints, aka\n CID-998912346c0d.(CVE-2020-11608)\n\n - ** DISPUTED ** An issue was discovered in the Linux\n kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c\n has a stack-based out-of-bounds write because an empty\n nodelist is mishandled during mount option parsing, aka\n CID-aa9f7d5172fa. NOTE: Someone in the security\n community disagrees that this is a vulnerability\n because the issue 'is a bug in parsing mount options\n which can only be specified by a privileged user, so\n triggering the bug does not grant any powers not\n already held.'.(CVE-2020-11565)\n\n - In the Linux kernel before 5.4.12,\n drivers/input/input.c has out-of-bounds writes via a\n crafted keycode table, as demonstrated by\n input_set_keycode, aka\n CID-cb222aed03d7.(CVE-2019-20636)\n\n - In the Linux kernel before 5.5.8, get_raw_socket in\n drivers/vhost/net.c lacks validation of an sk_family\n field, which might allow attackers to trigger kernel\n stack corruption via crafted system\n calls.(CVE-2020-10942)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

This allowed local users to cause a\n denial-of-service (crash) or obtain sensitive\n information from kernel memory.\n\n - CVE-2020-10942\n It was discovered that the vhost_net driver did not\n properly validate the type of sockets set as back-ends.\n A local user permitted to access /dev/vhost-net could\n use this to cause a stack corruption via crafted system\n calls, resulting in denial of service (crash) or\n possibly privilege escalation.\n\n - CVE-2020-11565\n Entropy Moe reported that the shared memory filesystem\n (tmpfs) did not correctly handle an 'mpol' mount option\n specifying an empty node list, leading to a stack-based\n out-of-bounds write. If user namespaces are enabled, a\n local user could use this to cause a denial of service\n (crash) or possibly for privilege escalation.\n\n - CVE-2020-11884\n Al Viro reported a race condition in memory management\n code for IBM Z (s390x architecture), that can result in\n the kernel executing code from the user address space.

"2023-05-18T14:59:02", "description": "The SUSE Linux Enterprise 15 SP1 RT kernel was updated to receive various security and bugfixes.\n\nThe following security bugs were fixed :\n\nCVE-2020-8834: KVM on Power8 processors had a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability to run code in kernel space of a guest VM can cause the host kernel to panic (bnc#1168276).\n\nCVE-2020-11494: An issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424).\n\nCVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls (bnc#1167629).\n\nCVE-2020-8647: Fixed a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929).\n\nCVE-2020-8649: Fixed a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931).\n\nCVE-2020-9383: Fixed an issue in set_fdc in drivers/block/floppy.c, which leads to a wait_til_ready out-of-bounds read (bnc#1165111).\n\nCVE-2019-9458: In the video driver there was a use after free due to a race condition.

"description": "Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.\n\n - CVE-2019-2182 Hanjun Guo and Lei Li reported a race condition in the arm64 virtual memory management code, which could lead to an information disclosure, denial of service (crash), or possibly privilege escalation.\n\n - CVE-2019-5108 Mitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations.\n\n - CVE-2019-19319 Jungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation.\n\n - CVE-2019-19462 The syzbot tool found a missing error check in the 'relay' library used to implement various files under debugfs. A local user permitted to access debugfs could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\n - CVE-2019-19768 Tristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation.\n\n - CVE-2019-20806 A potential NULL pointer dereference was discovered in the tw5864 media driver. The security impact of this is unclear.\n\n - CVE-2019-20811 The Hulk Robot tool found a reference-counting bug in an error path in the network subsystem. The security impact of this is unclear.\n\n - CVE-2020-0543 Researchers at VU Amsterdam discovered that on some Intel CPUs supporting the RDRAND and RDSEED instructions, part of a random value generated by these instructions may be used in a later speculative execution on any core of the same physical CPU.\n Depending on how these instructions are used by applications, a local user or VM guest could use this to obtain sensitive information such as cryptographic keys from other users or VMs.\n\n This vulnerability can be mitigated by a microcode update, either as part of system firmware (BIOS) or through the intel-microcode package in Debian's non-free archive section. This kernel update only provides reporting of the vulnerability and the option to disable the mitigation if it is not needed.\n\n - CVE-2020-2732 Paulo Bonzini discovered that the KVM implementation for Intel processors did not properly handle instruction emulation for L2 guests when nested virtualization is enabled. This could allow an L2 guest to cause privilege escalation, denial of service, or information leaks in the L1 guest.\n\n - CVE-2020-8428 Al Viro discovered a potential use-after-free in the filesystem core (vfs). A local user could exploit this to cause a denial of service (crash) or possibly to obtain sensitive information from the kernel.\n\n - CVE-2020-8647, CVE-2020-8649 The Hulk Robot tool found a potential MMIO out-of-bounds access in the vgacon driver. A local user permitted to access a virtual terminal (/dev/tty1 etc.) on a system using the vgacon driver could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\n - CVE-2020-8648 The syzbot tool found a race condition in the the virtual terminal driver, which could result in a use-after-free. A local user permitted to access a virtual terminal could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\n - CVE-2020-9383 Jordy Zomer reported an incorrect range check in the floppy driver which could lead to a static out-of-bounds access. A local user permitted to access a floppy drive could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\n - CVE-2020-10711 Matthew Sheets reported NULL pointer dereference issues in the SELinux subsystem while receiving CIPSO packet with null category. A remote attacker can take advantage of this flaw to cause a denial of service (crash). Note that this issue does not affect the binary packages distributed in Debian as CONFIG_NETLABEL is not enabled.\n\n - CVE-2020-10732 An information leak of kernel private memory to userspace was found in the kernel's implementation of core dumping userspace processes.\n\n - CVE-2020-10751 Dmitry Vyukov reported that the SELinux subsystem did not properly handle validating multiple messages, which could allow a privileged attacker to bypass SELinux netlink restrictions.\n\n - CVE-2020-10757 Fan Yang reported a flaw in the way mremap handled DAX hugepages, allowing a local user to escalate their privileges\n\n - CVE-2020-10942 It was discovered that the vhost_net driver did not properly validate the type of sockets set as back-ends.\n A local user permitted to access /dev/vhost-net could use this to cause a stack corruption via crafted system calls, resulting in denial of service (crash) or possibly privilege escalation.\n\n - CVE-2020-11494 It was discovered that the slcan (serial line CAN) network driver did not fully initialise CAN headers for received packets, resulting in an information leak from the kernel to user-space or over the CAN network.\n\n - CVE-2020-11565 Entropy Moe reported that the shared memory filesystem (tmpfs) did not correctly handle an 'mpol' mount option specifying an empty node list, leading to a stack-based out-of-bounds write.

privilege escalation, denial of service or information leaks.\n\nCVE-2019-2182\n\nHanjun Guo and Lei Li reported a race condition in the arm64 virtual memory management code, which could lead to an information disclosure, denial of service (crash), or possibly privilege escalation.\n\nCVE-2019-5108\n\nMitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations.\n\nCVE-2019-19319\n\nJungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation.\n\nCVE-2019-19462\n\nThe syzbot tool found a missing error check in the 'relay' library used to implement various files under debugfs. A local user permitted to access debugfs could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2019-19768\n\nTristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation.\n\nCVE-2019-20806\n\nA potential NULL pointer dereference was discovered in the tw5864 media driver. The security impact of this is unclear.\n\nCVE-2019-20811\n\nThe Hulk Robot tool found a reference-counting bug in an error path in the network subsystem. The security impact of this is unclear.\n\nCVE-2020-0543\n\nResearchers at VU Amsterdam discovered that on some Intel CPUs supporting the RDRAND and RDSEED instructions, part of a random value generated by these instructions may be used in a later speculative execution on any core of the same physical CPU. Depending on how these instructions are used by applications, a local user or VM guest could use this to obtain sensitive information such as cryptographic keys from other users or VMs.\n\nThis vulnerability can be mitigated by a microcode update, either as part of system firmware (BIOS) or through the intel-microcode package in Debian's non-free archive section. This kernel update only provides reporting of the vulnerability and the option to disable the mitigation if it is not needed.\n\nCVE-2020-2732\n\nPaulo Bonzini discovered that the KVM implementation for Intel processors did not properly handle instruction emulation for L2 guests when nested virtualization is enabled. This could allow an L2 guest to cause privilege escalation, denial of service, or information leaks in the L1 guest.\n\nCVE-2020-8428\n\nAl Viro discovered a potential use-after-free in the filesystem core (vfs). A local user could exploit this to cause a denial of service (crash) or possibly to obtain sensitive information from the kernel.\n\nCVE-2020-8647, CVE-2020-8649\n\nThe Hulk Robot tool found a potential MMIO out-of-bounds access in the vgacon driver. A local user permitted to access a virtual terminal (/dev/tty1 etc.) on a system using the vgacon driver could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-8648\n\nThe syzbot tool found a race condition in the the virtual terminal driver, which could result in a use-after-free. A local user permitted to access a virtual terminal could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-9383\n\nJordy Zomer reported an incorrect range check in the floppy driver which could lead to a static out-of-bounds access. A local user permitted to access a floppy drive could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-10711\n\nMatthew Sheets reported NULL pointer dereference issues in the SELinux subsystem while receiving CIPSO packet with null category. A remote attacker can take advantage of this flaw to cause a denial of service (crash). Note that this issue does not affect the binary packages distributed in Debian as CONFIG_NETLABEL is not enabled.\n\nCVE-2020-10732\n\nAn information leak of kernel private memory to userspace was found in the kernel's implementation of core dumping userspace processes.\n\nCVE-2020-10751\n\nDmitry Vyukov reported that the SELinux subsystem did not properly handle validating multiple messages, which could allow a privileged attacker to bypass SELinux netlink restrictions.\n\nCVE-2020-10757\n\nFan Yang reported a flaw in the way mremap handled DAX hugepages, allowing a local user to escalate their privileges\n\nCVE-2020-10942\n\nIt was discovered that the vhost_net driver did not properly validate the type of sockets set as back-ends. A local user permitted to access /dev/vhost-net could use this to cause a stack corruption via crafted system calls, resulting in denial of service (crash) or possibly privilege escalation.\n\nCVE-2020-11494\n\nIt was discovered that the slcan (serial line CAN) network driver did not fully initialise CAN headers for received packets, resulting in an information leak from the kernel to user-space or over the CAN network.\n\nCVE-2020-11565\n\nEntropy Moe reported that the shared memory filesystem (tmpfs) did not correctly handle an 'mpol' mount option specifying an empty node list, leading to a stack-based out-of-bounds write. If user namespaces are enabled, a local user could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-11608, CVE-2020-11609, CVE-2020-11668\n\nIt was discovered that the ov519, stv06xx, and xirlink_cit media drivers did not properly validate USB device descriptors. A physically present user with a specially constructed USB device could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-12114\n\nPiotr Krysiuk discovered a race condition between the umount and pivot_root operations in the filesystem core (vfs). A local user with the CAP_SYS_ADMIN capability in any user namespace could use this to cause a denial of service (crash).\n\nCVE-2020-12464\n\nKyungtae Kim reported a race condition in the USB core that can result in a use-after-free. It is not clear how this can be exploited, but it could result in a denial of service (crash or memory corruption) or privilege escalation.\n\nCVE-2020-12652\n\nTom Hatskevich reported a bug in the mptfusion storage drivers. An ioctl handler fetched a parameter from user memory twice, creating a race condition which could result in incorrect locking of internal data structures. A local user permitted to access /dev/mptctl could use this to cause a denial of service (crash or memory corruption) or for privilege escalation.\n\nCVE-2020-12653\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate scan requests, resulting a potential heap buffer overflow. A local user with CAP_NET_ADMIN capability could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-12654\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate WMM parameters received from an access point (AP), resulting a potential heap buffer overflow. A malicious AP could use this to cause a denial of service (crash or memory corruption) or possibly to execute code on a vulnerable system.\n\nCVE-2020-12770\n\nIt was discovered that the sg (SCSI generic) driver did not correctly release internal resources in a particular error case. A local user permitted to access an sg device could possibly use this to cause a denial of service (resource exhaustion).\n\nCVE-2020-13143\n\nKyungtae Kim reported a potential heap out-of-bounds write in the USB gadget subsystem. A local user permitted to write to the gadget configuration filesystem could use this to cause a denial of service (crash or memory corruption) or potentially for privilege escalation.\n\nFor Debian 8 'Jessie', these problems have been fixed in version 4.9.210-1+deb9u1~deb8u1. This version also fixes some related bugs that do not have their own CVE IDs, and a regression in the macvlan driver introduced in the previous security update (bug #952660).\n\nWe recommend that you upgrade your linux-4.9 packages.\n\nNOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

The security impact of this is unclear.\n\nCVE-2020-0543\n\nResearchers at VU Amsterdam discovered that on some Intel CPUs\nsupporting the RDRAND and RDSEED instructions, part of a random value\ngenerated by these instructions may be used in a later speculative\nexecution on any core of the same physical CPU. Depending on how these\ninstructions are used by applications, a local user or VM guest could\nuse this to obtain sensitive information such as cryptographic keys\nfrom other users or VMs.\n\nThis vulnerability can be mitigated by a microcode update,\neither as part of system firmware (BIOS) or through the\nintel-microcode package in Debian's non-free archive\nsection. This kernel update only provides reporting of the\nvulnerability and the option to disable the mitigation if it\nis not needed.\n\nCVE-2020-2732\n\nPaulo Bonzini discovered that the KVM implementation for Intel\nprocessors did not properly handle instruction emulation for L2 guests\nwhen nested virtualization is enabled. This could allow an L2 guest to\ncause privilege escalation, denial of service, or information leaks in\nthe L1 guest.\n\nCVE-2020-8428\n\nAl Viro discovered a potential use-after-free in the filesystem core\n(vfs). A local user could exploit this to cause a denial of service\n(crash) or possibly to obtain sensitive information from the kernel.\n\nCVE-2020-8647, CVE-2020-8649\n\nThe Hulk Robot tool found a potential MMIO out-of-bounds access in the\nvgacon driver. A local user permitted to access a virtual terminal\n(/dev/tty1 etc.) on a system using the vgacon driver could use this to\ncause a denial of service (crash or memory corruption) or possibly for\nprivilege escalation.\n\nCVE-2020-8648\n\nThe syzbot tool found a race condition in the the virtual terminal\ndriver, which could result in a use-after-free. A local user permitted\nto access a virtual terminal could use this to cause a denial of\nservice (crash or memory corruption) or possibly for privilege\nescalation.\n\nCVE-2020-9383\n\nJordy Zomer reported an incorrect range check in the floppy driver\nwhich could lead to a static out-of-bounds access. A local user\npermitted to access a floppy drive could use this to cause a denial of\nservice (crash or memory corruption) or possibly for privilege\nescalation.\n\nCVE-2020-10711\n\nMatthew Sheets reported NULL pointer dereference issues in the SELinux\nsubsystem while receiving CIPSO packet with null category. A remote\nattacker can take advantage of this flaw to cause a denial of service\n(crash). Note that this issue does not affect the binary packages\ndistributed in Debian as CONFIG_NETLABEL is not enabled.\n\nCVE-2020-10732\n\nAn information leak of kernel private memory to userspace was found in\nthe kernel's implementation of core dumping userspace processes.\n\nCVE-2020-10751\n\nDmitry Vyukov reported that the SELinux subsystem did not properly\nhandle validating multiple messages, which could allow a privileged\nattacker to bypass SELinux netlink restrictions.\n\nCVE-2020-10757\n\nFan Yang reported a flaw in the way mremap handled DAX hugepages,\nallowing a local user to escalate their privileges\n\nCVE-2020-10942\n\nIt was discovered that the vhost_net driver did not properly validate\nthe type of sockets set as back-ends. A local user permitted to access\n/dev/vhost-net could use this to cause a stack corruption via crafted\nsystem calls, resulting in denial of service (crash) or possibly\nprivilege escalation.\n\nCVE-2020-11494\n\nIt was discovered that the slcan (serial line CAN) network driver did\nnot fully initialise CAN headers for received packets, resulting in an\ninformation leak from the kernel to user-space or over the CAN\nnetwork.\n\nCVE-2020-11565\n\nEntropy Moe reported that the shared memory filesystem (tmpfs) did not\ncorrectly handle an 'mpol' mount option specifying an empty node list,\nleading to a stack-based out-of-bounds write. If user namespaces are\nenabled, a local user could use this to cause a denial of service\n(crash) or possibly for privilege escalation.\n\nCVE-2020-11608, CVE-2020-11609, CVE-2020-11668\n\nIt was discovered that the ov519, stv06xx, and xirlink_cit media\ndrivers did not properly validate USB device descriptors. A physically\npresent user with a specially constructed USB device could use this to\ncause a denial of service (crash) or possibly for privilege\nescalation.\n\nCVE-2020-12114\n\nPiotr Krysiuk discovered a race condition between the umount and\npivot_root operations in the filesystem core (vfs). A local user with\nthe CAP_SYS_ADMIN capability in any user namespace could use this to\ncause a denial of service (crash).\n\nCVE-2020-12464\n\nKyungtae Kim reported a race condition in the USB core that can result\nin a use-after-free. It is not clear how this can be exploited, but it\ncould result in a denial of service (crash or memory corruption) or\nprivilege escalation.\n\nCVE-2020-12652\n\nTom Hatskevich reported a bug in the mptfusion storage drivers. An\nioctl handler fetched a parameter from user memory twice, creating a\nrace condition which could result in incorrect locking of internal\ndata structures. A local user permitted to access /dev/mptctl could\nuse this to cause a denial of service (crash or memory corruption) or\nfor privilege escalation.\n\nCVE-2020-12653\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently\nvalidate scan requests, resulting a potential heap buffer overflow. A\nlocal user with CAP_NET_ADMIN capability could use this to cause a\ndenial of service (crash or memory corruption) or possibly for\nprivilege escalation.\n\nCVE-2020-12654\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently\nvalidate WMM parameters received from an access point (AP), resulting\na potential heap buffer overflow. A malicious AP could use this to\ncause a denial of service (crash or memory corruption) or possibly to\nexecute code on a vulnerable system.\n\nCVE-2020-12770\n\nIt was discovered that the sg (SCSI generic) driver did not correctly\nrelease internal resources in a particular error case. A local user\npermitted to access an sg device could possibly use this to cause a\ndenial of service (resource exhaustion).\n\nCVE-2020-13143\n\nKyungtae Kim reported a potential heap out-of-bounds write in the USB\ngadget subsystem. A local user permitted to write to the gadget\nconfiguration filesystem could use this to cause a denial of service\n(crash or memory corruption) or potentially for privilege escalation.\n\nFor Debian 8 'Jessie', these problems have been fixed in version\n4.9.210-1+deb9u1~deb8u1. This version also fixes some related bugs\nthat do not have their own CVE IDs, and a regression in the macvlan\ndriver introduced in the previous security update (bug #952660).\n\nWe recommend that you upgrade your linux-4.9 packages.\n\nNOTE: Tenable Network Security has extracted the preceding description\nblock directly from the DLA security advisory.

12 SP4 azure kernel was updated to receive various security and bugfixes.\n\nThe following security bugs were fixed :\n\nCVE-2020-8834: KVM on Power8 processors had a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability to run code in kernel space of a guest VM can cause the host kernel to panic (bnc#1168276).\n\nCVE-2020-11494: An issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424).\n\nCVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls (bnc#1167629).\n\nCVE-2019-9458: In the video driver there was a use after free due to a race condition.

For reference the original advisory text follows.\n\nSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.\n\nCVE-2015-8839\n\nA race condition was found in the ext4 filesystem implementation. A local user could exploit this to cause a denial of service (filesystem corruption).\n\nCVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613\n\nWen Xu from SSLab at Gatech reported that crafted Btrfs volumes could trigger a crash (Oops) and/or out-of-bounds memory access. An attacker able to mount such a volume could use this to cause a denial of service or possibly for privilege escalation.\n\nCVE-2019-5108\n\nMitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations.\n\nCVE-2019-19319\n\nJungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation.\n\nCVE-2019-19447\n\nIt was discovered that the ext4 filesystem driver did not safely handle unlinking of an inode that, due to filesystem corruption, already has a link count of 0. An attacker able to mount arbitrary ext4 volumes could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-19768\n\nTristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation.\n\nCVE-2019-20636\n\nThe syzbot tool found that the input subsystem did not fully validate keycode changes, which could result in a heap out-of-bounds write. A local user permitted to access the device node for an input or VT device could possibly use this to cause a denial of service (crash or memory corruption) or for privilege escalation.\n\nCVE-2020-0009\n\nJann Horn reported that the Android ashmem driver did not prevent read-only files from being memory-mapped and then remapped as read-write. However, Android drivers are not enabled in Debian kernel configurations.\n\nCVE-2020-0543\n\nResearchers at VU Amsterdam discovered that on some Intel CPUs supporting the RDRAND and RDSEED instructions, part of a random value generated by these instructions may be used in a later speculative execution on any core of the same physical CPU. Depending on how these instructions are used by applications, a local user or VM guest could use this to obtain sensitive information such as cryptographic keys from other users or VMs.\n\nThis vulnerability can be mitigated by a microcode update, either as part of system firmware (BIOS) or through the intel-microcode package in Debian's non-free archive section. This kernel update only provides reporting of the vulnerability and the option to disable the mitigation if it is not needed.\n\nCVE-2020-1749\n\nXiumei Mu reported that some network protocols that can run on top of IPv6 would bypass the Transformation (XFRM) layer used by IPsec, IPcomp/IPcomp6, IPIP, and IPv6 Mobility. This could result in disclosure of information over the network, since it would not be encrypted or routed according to the system policy.\n\nCVE-2020-2732\n\nPaulo Bonzini discovered that the KVM implementation for Intel processors did not properly handle instruction emulation for L2 guests when nested virtualization is enabled. This could allow an L2 guest to cause privilege escalation, denial of service, or information leaks in the L1 guest.\n\nCVE-2020-8647, CVE-2020-8649\n\nThe Hulk Robot tool found a potential MMIO out-of-bounds access in the vgacon driver. A local user permitted to access a virtual terminal (/dev/tty1 etc.) on a system using the vgacon driver could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-8648\n\nThe syzbot tool found a race condition in the the virtual terminal driver, which could result in a use-after-free. A local user permitted to access a virtual terminal could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-9383\n\nJordy Zomer reported an incorrect range check in the floppy driver which could lead to a static out-of-bounds access. A local user permitted to access a floppy drive could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-10690\n\nIt was discovered that the PTP hardware clock subsystem did not properly manage device lifetimes. Removing a PTP hardware clock from the system while a user process was using it could lead to a use-after-free. The security impact of this is unclear.\n\nCVE-2020-10751\n\nDmitry Vyukov reported that the SELinux subsystem did not properly handle validating multiple messages, which could allow a privileged attacker to bypass SELinux netlink restrictions.\n\nCVE-2020-10942\n\nIt was discovered that the vhost_net driver did not properly validate the type of sockets set as back-ends. A local user permitted to access /dev/vhost-net could use this to cause a stack corruption via crafted system calls, resulting in denial of service (crash) or possibly privilege escalation.\n\nCVE-2020-11494\n\nIt was discovered that the slcan (serial line CAN) network driver did not fully initialise CAN headers for received packets, resulting in an information leak from the kernel to user-space or over the CAN network.\n\nCVE-2020-11565\n\nEntropy Moe reported that the shared memory filesystem (tmpfs) did not correctly handle an 'mpol' mount option specifying an empty node list, leading to a stack-based out-of-bounds write. If user namespaces are enabled, a local user could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-11608, CVE-2020-11609, CVE-2020-11668\n\nIt was discovered that the ov519, stv06xx, and xirlink_cit media drivers did not properly validate USB device descriptors. A physically present user with a specially constructed USB device could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-12114\n\nPiotr Krysiuk discovered a race condition between the umount and pivot_root operations in the filesystem core (vfs). A local user with the CAP_SYS_ADMIN capability in any user namespace could use this to cause a denial of service (crash).\n\nCVE-2020-12464\n\nKyungtae Kim reported a race condition in the USB core that can result in a use-after-free. It is not clear how this can be exploited, but it could result in a denial of service (crash or memory corruption) or privilege escalation.\n\nCVE-2020-12652\n\nTom Hatskevich reported a bug in the mptfusion storage drivers. An ioctl handler fetched a parameter from user memory twice, creating a race condition which could result in incorrect locking of internal data structures. A local user permitted to access /dev/mptctl could use this to cause a denial of service (crash or memory corruption) or for privilege escalation.\n\nCVE-2020-12653\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate scan requests, resulting a potential heap buffer overflow. A local user with CAP_NET_ADMIN capability could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-12654\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate WMM parameters received from an access point (AP), resulting a potential heap buffer overflow. A malicious AP could use this to cause a denial of service (crash or memory corruption) or possibly to execute code on a vulnerable system.\n\nCVE-2020-12769\n\nIt was discovered that the spi-dw SPI host driver did not properly serialise access to its internal state. The security impact of this is unclear, and this driver is not included in Debian
