It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will access the freed drm_vgem_gem_object. (CVE-2022-1419)\n\n - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. (CVE-2022-1652)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use after free both read or write when non synchronized between cleanup routine and firmware download routine.\n (CVE-2022-1734)\n\n - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.", "published": "2022-07-01T00:00:00", "modified":

It is actually both for cgroup2 and cgroup1 versions of\n control groups. A local user could use this flaw to crash the system or escalate their privileges on the\n system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in\n the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem\n while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This\n flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a\n leak of internal kernel information. (CVE-2022-1353)\n\n - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount\n of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will\n access the freed drm_vgem_gem_object. (CVE-2022-1419)\n\n - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency\n use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker\n could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the\n system. (CVE-2022-1652)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user\n forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local\n user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use\n after free both read or write when non synchronized between cleanup routine and firmware download routine.\n (CVE-2022-1734)\n\n - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c.

This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)\n\n - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1048)\n\n - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. (CVE-2022-1652)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use after free both read or write when non synchronized between cleanup routine and firmware download routine.\n (CVE-2022-1734)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state.

remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1668-1 advisory.\n\n - An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR. (CVE-2018-7755)\n\n - An issue was discovered in the Linux kernel before 5.0.6. In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.\n (CVE-2019-20811)\n\n - There is a flaw reported in the Linux kernel in versions before 5.9 in drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker with a local account with a root privilege, can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. (CVE-2021-20292)\n\n - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.\n (CVE-2021-20321)\n\n - net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure of a bind call. (CVE-2021-38208)\n\n - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)\n\n - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().\n This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. (CVE-2022-1011)\n\n - A use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service (DoS) or a kernel information leak. (CVE-2022-1280)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will access the freed drm_vgem_gem_object. (CVE-2022-1419)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols functionality in the way a user terminates their session using a simulated Ethernet card and continued usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)\n\n - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c.

In rx_queue_add_kobject() and\n netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.\n (CVE-2019-20811)\n\n - There is a flaw reported in the Linux kernel in versions before 5.9 in\n drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue\n results from the lack of validating the existence of an object prior to performing operations on the\n object. An attacker with a local account with a root privilege, can leverage this vulnerability to\n escalate privileges and execute code in the context of the kernel. (CVE-2021-20292)\n\n - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users\n do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.\n (CVE-2021-20321)\n\n - net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial\n of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure\n of a bind call. (CVE-2021-38208)\n\n - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in\n the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)\n\n - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().\n This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in\n privilege escalation. (CVE-2022-1011)\n\n - A use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux\n kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of\n service (DoS) or a kernel information leak. (CVE-2022-1280)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This\n flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a\n leak of internal kernel information. (CVE-2022-1353)\n\n - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount\n of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will\n access the freed drm_vgem_gem_object. (CVE-2022-1419)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols\n functionality in the way a user terminates their session using a simulated Ethernet card and continued\n usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)\n\n - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.\n (CVE-2019-20811)\n\n - There is a flaw reported in the Linux kernel in versions before 5.9 in drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker with a local account with a root privilege, can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. (CVE-2021-20292)\n\n - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.\n (CVE-2021-20321)\n\n - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)\n\n - net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure of a bind call. (CVE-2021-38208)\n\n - In bpf_prog_test_run_skb of test_run.c, there is a possible out of bounds read due to Incorrect Size Value. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-154175781References: Upstream kernel (CVE-2021-39711)\n\n - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)\n\n - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().\n This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. (CVE-2022-1011)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will access the freed drm_vgem_gem_object. (CVE-2022-1419)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols functionality in the way a user terminates their session using a simulated Ethernet card and continued usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)\n\n - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. (CVE-2022-1652)\n\n - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use after free both read or write when non synchronized between cleanup routine and firmware download routine.\n (CVE-2022-1734)\n\n - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21123)\n\n - Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)\n\n - Incomplete cleanup in specific special register read operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21127)\n\n - Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21166)\n\n - Improper input validation for some Intel(R) Processors may allow an authenticated user to potentially cause a denial of service via local access. (CVE-2022-21180)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag.
