Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：ice: xsk: prohibit usage of non-balanced queue id Fix the following scenario: 1. ethtool -L $IFACE rx 8 tx 96 2. xdpsock -q 10 -t -z Above refers to a case where user would like to attach XSK socket in txonly mode at a queue id that does not have a corresponding Rx queue. At this moment ice's XSK logic is tightly bound to act on a queue pair, e.g. both Tx and Rx queues at a given queue id are disabled/enabled and both of them will get XSK pool assigned, which is broken for the presented queue configuration. This results in the splat included at the bottom, which is basically an OOB access to Rx ring array. To fix this, allow using the ids only in scope of combined queues reported by ethtool. However, logic should be rewritten to allow such configurations later on, which would end up as a complete rewrite of the control path, so let us go with this temporary fix.

  - 已修复 Linux 内核中的下列漏洞：ASoC: SOF: Intel: hda-ipc: Do not process IPC reply before firmware boot It is not yet clear, but it is possible to create a firmware so broken that it will send a reply message before a FW_READY message (it is not yet clear if FW_READY will arrive later). Since the reply_data is allocated only after the FW_READY message, this will lead to a NULL pointer dereference if not filtered out. The issue was reported with IPC4 firmware but the same condition is present for IPC3. (CVE-2022-50015)

如 TuxCare CENTOS8.5：CLSA-2025：1757962453公告所述，CentOS Linux 8.5 主机上存在安装的程序包，该漏洞会受到多个漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：netfilter: nft_tproxy: restrict to prerouting hook TPROXY is only allowed from prerouting, but nft_tproxy doesn't check this. This fixes a crash (null dereference) when using tproxy from e.g. output. (CVE-2022-50001)

  - 已修复 Linux 内核中的下列漏洞：ice: xsk: prohibit usage of non-balanced queue id Fix the following scenario: 1. ethtool -L $IFACE rx 8 tx 96 2. xdpsock -q 10 -t -z Above refers to a case where user would like to attach XSK socket in txonly mode at a queue id that does not have a corresponding Rx queue. At this moment ice's XSK logic is tightly bound to act on a queue pair, e.g. both Tx and Rx queues at a given queue id are disabled/enabled and both of them will get XSK pool assigned, which is broken for the presented queue configuration. This results in the splat included at the bottom, which is basically an OOB access to Rx ring array. To fix this, allow using the ids only in scope of combined queues reported by ethtool. However, logic should be rewritten to allow such configurations later on, which would end up as a complete rewrite of the control path, so let us go with this temporary fix.

  - 已修复 Linux 内核中的下列漏洞：ASoC: SOF: Intel: hda-ipc: Do not process IPC reply before firmware boot It is not yet clear, but it is possible to create a firmware so broken that it will send a reply message before a FW_READY message (it is not yet clear if FW_READY will arrive later). Since the reply_data is allocated only after the FW_READY message, this will lead to a NULL pointer dereference if not filtered out. The issue was reported with IPC4 firmware but the same condition is present for IPC3. (CVE-2022-50015)
