      <description>&lt;p&gt;An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931.&lt;/p&gt;</description>

      <title>OESA-2021-1111 — kernel security update</title>
      <link>https://cve.radiocsirt.org/vuln/oesa-2021-1111</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; openEuler:20.03-LTS: kernel, openEuler:20.03-LTS-SP1: kernel&lt;/p&gt;
&lt;p&gt;The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.&#13;
&#13;
Security Fix(es):&#13;
&#13;
An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn&amp;amp;apos;t correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.(CVE-2021-26931)&#13;
&#13;
An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn&amp;amp;apos;t mapped. In another case, internal state would be insufficiently updated, preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c.(CVE-2021-26930)&#13;
&#13;
An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant map…&lt;/p&gt;</description>
