ext4_protect_reserved_inode in fs/ext4/block_validity.c that allowed attackers to cause a soft lockup via a crafted journal size (bsc#1164069).\n\nCVE-2020-8648: Fixed a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bsc#1162928).\n\nCVE-2020-2732: Fixed an issue affecting Intel CPUs where an L2 guest may trick the L0 hypervisor into accessing

vulnerabilities :\n\n - In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c.(CVE-2019-19447 )\n\n - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).(CVE-2019-19768)\n\n - ext4_protect_reserved_inode in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992)\n\n - An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)\n\n - In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring.(CVE-2019-19807)\n\n - Kernel: kvm: nVMX: L2 guest may trick the L0 hypervisor to access sensitive L1 resources(CVE-2020-2732)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/n_tty.c.(CVE-2020-8648)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)\n\n - fs/namei.c in the Linux kernel before 5.5 has a may_create_in_sticky use-after-free, which allows local users to cause a denial of service (OOPS) or possibly obtain sensitive information from kernel memory, aka CID-d0cb50185ae9. One attack vector may be an open system call for a UNIX domain socket, if the socket is being moved to a new parent directory and its old parent directory is being removed.(CVE-2020-8428)\n\n - In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest.

This is related to\n snd_timer_open and snd_timer_close_locked. The timeri\n variable was originally intended to be for a newly\n created timer instance, but was used for a different\n purpose after refactoring.(CVE-2019-19807)\n\n - Kernel: kvm: nVMX: L2 guest may trick the L0 hypervisor\n to access sensitive L1 resources(CVE-2020-2732)\n\n - There is a use-after-free vulnerability in the Linux\n kernel through 5.5.2 in the n_tty_receive_buf_common\n function in drivers/tty/n_tty.c.(CVE-2020-8648)\n\n - There is a use-after-free vulnerability in the Linux\n kernel through 5.5.2 in the vgacon_invert_region\n function in\n drivers/video/console/vgacon.c.(CVE-2020-8649)\n\n - There is a use-after-free vulnerability in the Linux\n kernel through 5.5.2 in the vc_do_resize function in\n drivers/tty/vt/vt.c.(CVE-2020-8647)\n\n - fs/namei.c in the Linux kernel before 5.5 has a\n may_create_in_sticky use-after-free, which allows local\n users to cause a denial of service (OOPS) or possibly\n obtain sensitive information from kernel memory, aka\n CID-d0cb50185ae9.

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. A\n local user could use this for privilege escalation.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-2732\"\n );\n

Because of\nthis, an attacker with the ability to run code in kernel space of a\nguest VM can cause the host kernel to panic (bnc#1168276).\n\nCVE-2020-11494: An issue was discovered in slc_bump in\ndrivers/net/can/slcan.c, which allowed attackers to read uninitialized\ncan_frame data, potentially containing sensitive information from\nkernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL\n(bnc#1168424).\n\nCVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks\nvalidation of an sk_family field, which might allow attackers to\ntrigger kernel stack corruption via crafted system calls\n(bnc#1167629).\n\nCVE-2020-8647: Fixed a use-after-free vulnerability in the\nvc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929).\n\nCVE-2020-8649: Fixed a use-after-free vulnerability in the\nvgacon_invert_region function in drivers/video/console/vgacon.c\n(bnc#1162931).\n\nCVE-2020-9383: Fixed an issue in set_fdc in drivers/block/floppy.c,\nwhich 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\nrace condition. This could lead to local escalation of privilege with\nno additional execution privileges needed (bnc#1168295).\n\nCVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a\nsystem crash (bnc#1120386).\n\nCVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function\nin kernel/trace/blktrace.c (bnc#1159285).\n\nCVE-2019-19770: Fixed a use-after-free in the debugfs_remove function\n(bsc#1159198).\n\nThe update package also includes non-security fixes.

"The SUSE Linux Enterprise 12 SP4 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. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295).\n\nCVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386).\n\nCVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198).\n\nCVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S did not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390).\n\nCVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929).\n\nCVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931).\n\nCVE-2020-9383: An issue was discovered set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it (bnc#1165111).\n\nCVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285).\n\nThe update package also includes non-security fixes.

"The SUSE Linux Enterprise 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. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295).\n\nCVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386).\n\nCVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198).\n\nCVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S did not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390).\n\nCVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929).\n\nCVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931).\n\nCVE-2020-9383: An issue was discovered set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it (bnc#1165111).\n\nCVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285).\n\nThe update package also includes non-security fixes.

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.

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. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295).\n\nCVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386).\n\nCVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198).\n\nCVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S did not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390).\n\nCVE-2020-2732: Fixed an issue where under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest (bnc#1163971).\n\nCVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929 1164078).\n\nCVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162929 1162931).\n\nCVE-2020-9383: An issue was discovered set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it (bnc#1165111).\n\nCVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285).\n\nCVE-2018-20836: Fixed an issue where a race condition in smp_task_timedout() and smp_task_done() cloud lead to a use-after-free (bnc#1134395).\n\nThe update package also includes non-security fixes.

This could lead to local escalation of privilege with\nno additional execution privileges needed (bnc#1168295).\n\nCVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a\nsystem crash (bnc#1120386).\n\nCVE-2019-19770: Fixed a use-after-free in the debugfs_remove function\n(bsc#1159198).\n\nCVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S\ndid not have save/restore functionality for PNV_POWERSAVE_AMR,\nPNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390).\n\nCVE-2020-2732: Fixed an issue where under some circumstances, an L2\nguest may trick the L0 guest into accessing sensitive L1 resources\nthat should be inaccessible to the L2 guest (bnc#1163971).\n\nCVE-2020-8647: There was a use-after-free vulnerability in the\nvc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929 1164078).\n\nCVE-2020-8649: There was a use-after-free vulnerability in the\nvgacon_invert_region function in drivers/video/console/vgacon.c\n(bnc#1162929 1162931).\n\nCVE-2020-9383: An issue was discovered set_fdc in\ndrivers/block/floppy.c leads to a wait_til_ready out-of-bounds read\nbecause the FDC index is not checked for errors before assigning it\n(bnc#1165111).\n\nCVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function\nin kernel/trace/blktrace.c (bnc#1159285).\n\nCVE-2018-20836: Fixed an issue where a race condition in\nsmp_task_timedout() and smp_task_done() cloud lead to a use-after-free\n(bnc#1134395).\n\nThe update package also includes non-security fixes.

sub-buffer).(CVE-2019-19768)\n\n - The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.(CVE-2019-18675)\n\n - An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)\n\n - The time subsystem in the Linux kernel, when CONFIG_TIMER_STATS is enabled, allows local users to discover real PID values (as distinguished from PID values inside a PID namespace) by reading the /proc/timer_list file, related to the print_timer function in kernel/time/timer_list.c and the\n __timer_stats_timer_set_start_info function in kernel/time/timer.c.(CVE-2017-5967)\n\n - ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem.

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. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea.(CVE-2020-12653)\n\n - usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because a transfer occurs without a reference, aka CID-056ad39ee925.(CVE-2020-12464)\n\n - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a 'double fetch' vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states 'The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power.'(CVE-2020-12652)\n\n - In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors, aka CID-a246b4d54770.(CVE-2020-11668)\n\n - An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1.\n drivers/media/usb/gspca/stv06xx/stv06xx.c and drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c mishandle invalid descriptors, as demonstrated by a NULL pointer dereference, aka CID-485b06aadb93.(CVE-2020-11609)\n\n - An issue was discovered in the Linux kernel before 5.6.1. drivers/media/usb/gspca/ov519.c allows NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints, aka CID-998912346c0d.(CVE-2020-11608)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue 'is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.'.(CVE-2020-11565)\n\n - In the Linux kernel before 5.4.12, drivers/input/input.c has out-of-bounds writes via a crafted keycode table, as demonstrated by input_set_keycode, aka CID-cb222aed03d7.(CVE-2019-20636)\n\n - In the Linux kernel before 5.5.8, 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.(CVE-2020-10942)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.
