The CentOS Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS6:CLSA-2026:1768669128 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: scsi: target: Fix WRITE_SAME No Data     Buffer crash In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer     that gets written out. If this bit is set using commands like sg_write_same --ndob we will crash in     target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because     its NULL. This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support     it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal     WRITE SAME with no data buffer. (CVE-2022-21546)

  - 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.
    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-2022-23042)

  - A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function     security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use     this flaw to crash the system or potentially escalate their privileges on the system. (CVE-2022-2978)

  - The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer     overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send     buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer     to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC     message with garbage data is still correctly formed according to the specification and is passed forward     to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the     allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (CVE-2022-43945)

  - In the Linux kernel, the following vulnerability has been resolved: capabilities: fix undefined behavior     in bit shift for CAP_TO_MASK Shifting signed 32-bit value by 31 bits is undefined, so changing significant     bit to unsigned. The UBSAN warning calltrace like below: UBSAN: shift-out-of-bounds in     security/commoncap.c:1252:2 left shift of 1 by 31 places cannot be represented in type 'int' Call Trace:
