Summary

In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of debugfs within blktrace

    descriptionThe SUSE Linux Enterprise 12 SP5 azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-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). CVE-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). CVE-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). CVE-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). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-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). CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-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). CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). CVE-2018-20836: Fixed an issue where a race condition in smp_task_timedout() and smp_task_done() could lead to a use-after-free (bnc#1134395). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe SUSE Linux Enterprise 12 SP4 azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-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). CVE-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). CVE-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). CVE-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). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-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). CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-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). CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-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). CVE-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). CVE-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). CVE-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). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-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). CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-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). CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-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). CVE-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). CVE-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). CVE-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). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-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). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file).(CVE-2019-19770)mwifiex_tm_cmd in driverset/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service.(CVE-2019-20095)TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.(CVE-2019-11135)A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042.(CVE-2019-19062)In the Linux kernel before 5.1.6, there is a use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c.(CVE-2019-19543)In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel before 5.1.6, there is a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service, aka CID-dea37a972655.(CVE-2019-19966)An issue was discovered in drivers/xen/balloon.c in the Linux kernel before 5.2.3, as used in Xen through 4.12.x, allowing guest OS users to cause a denial of service because of unrestricted resource consumption during the mapping of guest memory, aka CID-6ef36ab967c7.(CVE-2019-17351)A memory leak in the crypto_reportstat() function in drivers/virt/vboxguest/vboxguest_utils.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering copy_form_user() failures, aka CID-e0b0cb938864.(CVE-2019-19048)kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel it only causes mismanagement of application execution.)(CVE-2019-19922)An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel
