LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates.

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.

When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition.

(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.

User interaction is\n not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-155756045References:\n Upstream kernel (CVE-2021-0707)\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 - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's\n cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting\n the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.\n (CVE-2021-4154)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux\n Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the\n offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw\n allows unprivileged local users on the host to write outside the userspace region and potentially corrupt\n the kernel, resulting in a denial of service condition. (CVE-2022-1158)\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\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets\n are in the intended state. (CVE-2022-28893)\n\n - drivers/infiniband/ulp/rtrs/rtrs-clt.c in the Linux kernel before 5.16.12 has a double free related to\n rtrs_clt_dev_release. (CVE-2022-29156)\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\",

vulnerabilities as referenced in the SUSE-SU-2022:1676-1 advisory.\n\n - A use after free in the Linux kernel infiniband hfi1 driver in versions prior to 5.10-rc6 was found in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system.\n (CVE-2020-27835)\n\n - In dma_buf_release of dma-buf.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-155756045References:\n Upstream kernel (CVE-2021-0707)\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 - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.\n (CVE-2021-4154)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition. (CVE-2022-1158)\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. (CVE-2022-28356)\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. (CVE-2022-28893)\n\n - drivers/infiniband/ulp/rtrs/rtrs-clt.c in the Linux kernel before 5.16.12 has a double free related to rtrs_clt_dev_release.

(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\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets\n are in the intended state. (CVE-2022-28893)\n\n - drivers/infiniband/ulp/rtrs/rtrs-clt.c in the Linux kernel before 5.16.12 has a double free related to\n rtrs_clt_dev_release. (CVE-2022-29156)\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\",

"description": "The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1669-1 advisory.\n\n - A use after free in the Linux kernel infiniband hfi1 driver in versions prior to 5.10-rc6 was found in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system.\n (CVE-2020-27835)\n\n - In dma_buf_release of dma-buf.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-155756045References:\n Upstream kernel (CVE-2021-0707)\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 - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.\n (CVE-2021-4154)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition. (CVE-2022-1158)\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.

A local user could use this flaw to crash the system.\n (CVE-2020-27835)\n\n - In dma_buf_release of dma-buf.c, there is a possible memory corruption due to a use after free. This could\n lead to local escalation of privilege with no additional execution privileges needed. User interaction is\n not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-155756045References:\n Upstream kernel (CVE-2021-0707)\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 - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's\n cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting\n the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.\n (CVE-2021-4154)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux\n Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the\n offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw\n allows unprivileged local users on the host to write outside the userspace region and potentially corrupt\n the kernel, resulting in a denial of service condition. (CVE-2022-1158)\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-2022-1048)\n\n - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path.

(CVE-2022-1048)\n\n - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path.

in the SUSE-SU-2022:1267-1 advisory.\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel (CVE-2021-39713)\n\n - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. (CVE-2021-45868)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace. (CVE-2022-0850)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\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 PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which can be triggered by the backend.

(CVE-2022-26490)\n\n - An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to obtain sensitive information from heap memory via crafted frame lengths from a device. (CVE-2022-26966)\n\n - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. (CVE-2022-27666)\n\n - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c.

As a result the backend can keep access\n to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of\n a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038\n gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,\n 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no\n longer in use, but the freeing of the related data page is not synchronized with dropping the granted\n access. As a result the backend can keep access to the memory page even after it has been freed and then\n re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to\n revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which\n can be triggered by the backend.

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 PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use.

As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose.

This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a\n corrupted quota file. (CVE-2021-45868)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux\n Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to\n userspace. (CVE-2022-0850)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a\n use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel\n information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\n\n - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers\n concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM\n for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the\n system. (CVE-2022-1048)\n\n - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to\n multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV\n device frontends are using the grant table interfaces for removing access rights of the backends in ways\n being subject to race conditions, resulting in potential data leaks, data corruption by malicious\n backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the\n gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they\n assume that a following removal of the granted access will always succeed, which is not true in case the\n backend has mapped the granted page between those two operations. As a result the backend can keep access\n to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of\n a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038\n gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,\n 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no\n longer in use, but the freeing of the related data page is not synchronized with dropping the granted\n access. As a result the backend can keep access to the memory page even after it has been freed and then\n re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to\n revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which\n can be triggered by the backend.

in the SUSE-SU-2022:1255-1 advisory.\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel (CVE-2021-39713)\n\n - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. (CVE-2021-45868)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace. (CVE-2022-0850)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\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 PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which can be triggered by the backend.

This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. (CVE-2021-45868)\n\n - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)\n\n - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace. (CVE-2022-0850)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\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 PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which can be triggered by the backend.

vulnerabilities :\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 - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.\n (CVE-2021-33656)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel (CVE-2021-39713)\n\n - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)\n\n - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\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 - An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP pacing can lead to memory/netns leak, which can be used by remote clients. (CVE-2022-1678)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. User interaction is not needed for exploitation.Product:\n AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel (CVE-2022-20008)\n\n - In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds read due to improper input validation. This could lead to local information disclosure if a malicious USB HID device were plugged in, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream kernel (CVE-2022-20132)\n\n - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead to local escalation of privilege when opening and closing inet sockets with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)\n\n - In lock_sock_nested of sock.c, there is a possible use after free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream kernel (CVE-2022-20154)\n\n - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-182388481References: Upstream kernel (CVE-2022-20166)\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information. (CVE-2022-23960)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\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. (CVE-2022-30594)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used. (CVE-2022-32296)\n\n - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.

User interaction is not needed for exploitation.Product:\n AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel (CVE-2022-20008)\n\n - In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds\n read due to improper input validation. This could lead to local information disclosure if a malicious USB\n HID device were plugged in, with no additional execution privileges needed. User interaction is not needed\n for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream\n kernel (CVE-2022-20132)\n\n - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead\n to local escalation of privilege when opening and closing inet sockets with no additional execution\n privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android\n kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)\n\n - In lock_sock_nested of sock.c, there is a possible use after free due to a race condition. This could lead\n to local escalation of privilege with System execution privileges needed. User interaction is not needed\n for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream\n kernel (CVE-2022-20154)\n\n - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer\n overflow. This could lead to local escalation of privilege with System execution privileges needed. User\n interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-182388481References: Upstream kernel (CVE-2022-20166)\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation,\n aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to\n influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive\n information. (CVE-2022-23960)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to\n cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14\n and later versions. (CVE-2022-29581)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers\n to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create\n user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to\n a use-after-free. (CVE-2022-32250)\n\n - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are\n used. (CVE-2022-32296)\n\n - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init\n (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different\n vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an\n unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data\n in net/netfilter/nf_tables_api.c.

This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.

LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system. (CVE-2022-2873)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects. (CVE-2022-2938)\n\n - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.\n (CVE-2022-2964)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. (CVE-2022-3239)\n\n - The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges. (CVE-2022-36123)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17.

(CVE-2021-33061)\n\n - In fs/eventpoll.c, there is a possible use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product:\n AndroidVersions: Android kernelAndroid ID: A-204450605References: Upstream kernel (CVE-2021-39634)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\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 - In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. User interaction is not needed for exploitation.Product:\n AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel (CVE-2022-20008)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\n\n - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system. (CVE-2022-2873)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects. (CVE-2022-2938)\n\n - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.\n (CVE-2022-2964)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. (CVE-2022-3239)\n\n - The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges. (CVE-2022-36123)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED situations. (CVE-2022-39189)\n\n - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

(CVE-2022-21166)\n\n - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which can be triggered by the backend. CVE-2022-23042 (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038, CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042)\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB.

(CVE-2022-0854)\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 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 - 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 - 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 - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated\n 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\n authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)\n\n - Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an\n authenticated user to potentially enable information disclosure via local access. (CVE-2022-21166)\n\n - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to\n multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV\n device frontends are using the grant table interfaces for removing access rights of the backends in ways\n being subject to race conditions, resulting in potential data leaks, data corruption by malicious\n backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the\n gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they\n assume that a following removal of the granted access will always succeed, which is not true in case the\n backend has mapped the granted page between those two operations. As a result the backend can keep access\n to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of\n a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038\n gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,\n 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no\n longer in use, but the freeing of the related data page is not synchronized with dropping the granted\n access. As a result the backend can keep access to the memory page even after it has been freed and then\n re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to\n revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which\n can be triggered by the backend. CVE-2022-23042 (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038,\n CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042)\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation,\n aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to\n influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive\n information. (CVE-2022-23960)\n\n - drivers/usb/gadget/legacy/inode.c in the Linux kernel through 5.16.8 mishandles dev->buf release.\n (CVE-2022-24958)\n\n - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has\n EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)\n\n - An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to\n obtain sensitive information from heap memory via crafted frame lengths from a device. (CVE-2022-26966)\n\n - In drivers/usb/gadget/udc/udc-xilinx.c in the Linux kernel before 5.16.12, the endpoint index is not\n validated and might be manipulated by the host for out-of-array access. (CVE-2022-27223)\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\n - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.\n (CVE-2022-28390)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers\n to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create\n user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to\n a use-after-free. (CVE-2022-32250)\n\n - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are\n used. (CVE-2022-32296)\n\n - drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of\n a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.\n (CVE-2022-33981)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n

(CVE-2022-0494)\n\n - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux\n Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\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\",

This\n could compromise the confidentiality and integrity of encrypted\n communications.\n\n The original fix for this issue had to be reverted because it\n caused the boot process to hang on many systems. In this version,\n the random driver has been updated, making it more effective in\n gathering entropy without needing a hardware RNG.\n\nCVE-2021-4149\n\n Hao Sun reported a flaw in the Btrfs fileysstem driver. There\n is a potential lock imbalance in an error path. A local user\n might be able to exploit this for denial of service.\n\nCVE-2021-39713\n\n The syzbot tool found a race condition in the network scheduling\n subsystem which could lead to a use-after-free. A local user\n could exploit this for denial of service (memory corruption or\n crash) or possibly for privilege escalation.\n\nCVE-2022-0494\n\n The scsi_ioctl() was susceptible to an information leak only\n exploitable by users with CAP_SYS_ADMIN or CAP_SYS_RAWIO\n capabilities.\n\nCVE-2022-0812\n\n It was discovered that the RDMA transport for NFS (xprtrdma)\n miscalculated the size of message headers, which could lead to a\n leak of sensitive information between NFS servers and clients.\n\nCVE-2022-0854\n\n Ali Haider discovered a potential information leak in the DMA\n subsystem. On systems where the swiotlb feature is needed, this\n might allow a local user to read sensitive information.\n\nCVE-2022-1011\n\n Jann Horn discovered a flaw in the FUSE (Filesystem in User-Space)\n implementation. A local user permitted to mount FUSE filesystems\n could exploit this to cause a use-after-free and read sensitive\n information.\n\nCVE-2022-1012, CVE-2022-32296\n\n Moshe Kol, Amit Klein, and Yossi Gilad discovered a weakness\n in randomisation of TCP source port selection.\n\nCVE-2022-1016\n\n David Bouman discovered a flaw in the netfilter subsystem where\n the nft_do_chain function did not initialize register data that\n nf_tables expressions can read from and write to. A local attacker\n can take advantage of this to read sensitive information.\n\nCVE-2022-1198\n\n Duoming Zhou discovered a race condition in the 6pack hamradio\n driver, which could lead to a use-after-free. A local user could\n exploit this to cause a denial of service (memory corruption or\n crash) or possibly for privilege escalation.\n\nCVE-2022-1199\n\n Duoming Zhou discovered race conditions in the AX.25 hamradio\n protocol, which could lead to a use-after-free or null pointer\n dereference. A local user could exploit this to cause a denial of\n service (memory corruption or crash) or possibly for privilege\n escalation.\n\nCVE-2022-1353\n\n The TCS Robot tool found an information leak in the PF_KEY\n subsystem. A local user can receive a netlink message when an\n IPsec daemon registers with the kernel, and this could include\n sensitive information.\n\nCVE-2022-1516\n\n A NULL pointer dereference flaw in the implementation of the X.25\n set of standardized network protocols, which can result in denial\n of service.\n\n This driver is not enabled in Debian's official kernel\n configurations.\n\nCVE-2022-1729\n\n Norbert Slusarek discovered a race condition in the perf subsystem\n which could result in local privilege escalation to root. The\n default settings in Debian prevent exploitation unless more\n permissive settings have been applied in the\n kernel.perf_event_paranoid sysctl.\n\nCVE-2022-1734\n\n Duoming Zhou discovered race conditions in the nfcmrvl NFC driver\n that could lead to a use-after-free, double-free or null pointer\n dereference. A local user might be able to exploit these for\n denial of service (crash or memory corruption) or possibly for\n privilege escalation.\n\n This driver is not enabled in Debian's official kernel\n configurations.\n\nCVE-2022-1974, CVE-2022-1975\n\n Duoming Zhou discovered that the NFC netlink interface was\n suspectible to denial of service.\n\nCVE-2022-2153\n\n "kangel" reported a flaw in the KVM implementation for x86\n processors which could lead to a null pointer dereference. A local\n user permitted to access /dev/kvm could exploit this to cause a\n denial of service (crash).\n\nCVE-2022-21123, CVE-2022-21125, CVE-2022-21166\n\n Various researchers discovered flaws in Intel x86 processors,\n collectively referred to as MMIO Stale Data vulnerabilities.\n These are similar to the previously published Microarchitectural\n Data Sampling (MDS) issues and could be exploited by local users\n to leak sensitive information.\n\n For some CPUs, the mitigations for these issues require updated\n microcode. An updated intel-microcode package may be provided at\n a later date. The updated CPU microcode may also be available as\n part of a system firmware ("BIOS") update.\n\n Further information on the mitigation can be found at\n <https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/processor_mmio_stale_data.html>\n or in the linux-doc-4.9 package.\n\nCVE-2022-23036, CVE-2022-23037, CVE-2022-23038, CVE-2022-23039,\nCVE-2022-23040, CVE-2022-23041, CVE-2022-23042 (XSA-396)\n\n Demi Marie Obenour and Simon Gaiser of Invisible Things Lab\n discovered flaws in several Xen PV device frontends. These drivers\n misused the Xen grant table API in a way that could be exploited\n by a malicious device backend to cause data corruption, leaks of\n sensitive information, or a denial of service (crash).\n\nCVE-2022-23960\n\n Researchers at VUSec discovered that the Branch History Buffer in\n Arm processors can be exploited to create information side-\n channels with speculative execution. This issue is similar to\n Spectre variant 2, but requires additional mitigations on some\n processors.\n\n This can be exploited to obtain sensitive information from a\n different security context, such as from user-space to the kernel,\n or from a KVM guest to the kernel.\n\nCVE-2022-24958\n\n A flaw was discovered that the USB gadget subsystem that could\n lead to a use-after-free. A local user permitted to configure USB\n gadgets could exploit this to cause a denial of service (crash or\n memory corruption) or possibly for privilege escalation.\n\nCVE-2022-26490\n\n Buffer overflows in the STMicroelectronics ST21NFCA core driver\n can result in denial of service or privilege escalation.\n\n This driver is not enabled in Debian's official kernel\n configurations.\n\nCVE-2022-26966\n\n A flaw was discovered in the sr9700 USB networking driver. A local\n user able to attach a specially designed USB device could use this\n to leak sensitive information.\n\nCVE-2022-27223\n\n A flaw was discovered in the udc-xilinx USB gadget-mode controller\n driver. On systems using this driver, a malicious USB host could\n exploit this to cause a denial of service (crash or memory\n corruption) or possibly to execute arbitrary code.\n\n This driver is not enabled in Debian's official kernel\n configurations.\n\nCVE-2022-28356\n\n "Beraphin" discovered that the ANSI/IEEE 802.2 LLC type 2 driver did\n not properly perform reference counting on some error paths. A\n local attacker can take advantage of this flaw to cause a denial\n of service.\n\nCVE-2022-28390\n\n A double free vulnerability was discovered in the EMS CPC-USB/ARM7\n CAN/USB interface driver.\n\nCVE-2022-30594\n\n Jann Horn discovered a flaw in the interaction between ptrace and\n seccomp subsystems. A process sandboxed using seccomp() but still\n permitted to use ptrace() could exploit this to remove the seccomp\n restrictions.\n\nCVE-2022-32250\n\n Aaron Adams discovered a use-after-free in Netfilter which may\n result in local privilege escalation to root.\n\nCVE-2022-33981\n\n Yuan Ming from Tsinghua University reported a a race condition in\n the floppy driver involving use of the FDRAWCMD ioctl, which could\n lead to a use-after-free. A local user with access to a floppy\n drive device could exploit this to cause a denial of service\n (crash or memory corruption) or possibly for privilege escalation.\n This ioctl is now disabled by default.\n\nFor Debian 9 stretch, these problems have been fixed in version\n4.9.320-2.\n\nFor the armhf architecture, this update enables optimised\nimplementations of several cryptographic and CRC algorithms. For at\nleast AES, this should remove a timing side-channel that could lead to\na leak of sensitive information.\n\nThis update includes many more bug fixes from stable updates\n4.9.304-4.9.320 inclusive. The random driver has been backported from\nLinux 5.19, fixing numerous performance and correctness issues. Some\nchanges will be visible:\n\n- The entropy pool size is now 256 bits instead of 4096. You may need\n to adjust the configuration of system monitoring or user-space\n entropy gathering services to allow for this.\n\n- On systems without a hardware RNG, the kernel will log many more\n uses of /dev/urandom before it is fully initialised. These uses\n were previously under-counted and this is not a regression.\n\nWe recommend that you upgrade your linux packages.\n\nFor the detailed security status of linux please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/linux\n\nFurther information about Debian LTS security advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://wiki.debian.org/LTS\nAttachment:\nsignature.asc\nDescription: PGP signature\n", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "baseScore": 8.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-07-01T11:40:50", "type": "debian", "title": "[SECURITY] [DLA 3065-1] linux security update", "bulletinFamily": "unix", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2018-1108", "CVE-2021-39713", "CVE-2021-4149", "CVE-2022-0494", "CVE-2022-0812", "CVE-2022-0854", "CVE-2022-1011", "CVE-2022-1012", "CVE-2022-1016", "CVE-2022-1198", "CVE-2022-1199", "CVE-2022-1353", "CVE-2022-1516", "CVE-2022-1729", "CVE-2022-1734", "CVE-2022-1974", "CVE-2022-1975", "CVE-2022-21123", "CVE-2022-21125", "CVE-2022-21166", "CVE-2022-2153", "CVE-2022-23036", "CVE-2022-23037", "CVE-2022-23038", "CVE-2022-23039", "CVE-2022-23040", "CVE-2022-23041", "CVE-2022-23042", "CVE-2022-23960", "CVE-2022-24958", "CVE-2022-26490", "CVE-2022-26966", "CVE-2022-27223", "CVE-2022-28356", "CVE-2022-28390", "CVE-2022-30594", "CVE-2022-32250", "CVE-2022-32296", "CVE-2022-33981"], "modified": "2022-07-01T11:40:50", "id": "DEBIAN:DLA-3065-1:C1710", "href": "https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}]}
