It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1798 advisory.\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 - 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\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 - 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 - 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\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.", "published": "2022-06-07T00:00:00", "modified":

{"lastseen": "2023-03-25T04:43:37", "description": "According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. 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 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\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 - 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-2022-23037)\n\n - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double free. (CVE-2022-28388)\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 - 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\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or\n CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)\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\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 - 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-2022-23037)\n\n - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double\n free.

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.
