The version of kernel installed on the remote host is prior to 5.10.205-195.804. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2024-045 advisory.

    A race condition leading to a use-after-free issue was found in the QXL driver in the Linux kernel.
    (CVE-2023-39198)

    An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an     io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

    When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 Packet     Too Big (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it     knows not to exceed this value when subsequently routing to the same host.

    In Linux kernels prior to 6.3, garbage collection is run on the IPv6 Destination Route Cache if the number     of entries exceeds a threshold when adding the destination to the cache. This garbage collection examines     every entry in the cache while holding a lock. In these affected kernel versions, a flood of the IPv6     ICMP6 PTB messages could cause high lock contention and increased CPU usage, leading to a Denial-of-     Service.

    The fix backports the garbage collection improvements from Linux kernel 6.3 by bringing the IPv6 code     closer to the IPv4 code, which does not have this issue.

    tcp: do not accept ACK of bytes we never sent (CVE-2023-52881)

    An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This flaw     allows a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data to be printed (and potentially leaked) to the kernel ring buffer (dmesg).
    (CVE-2023-6121)

    A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's     deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on.
    (CVE-2023-6531)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double     deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.

    We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a. (CVE-2023-6817)

    A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation.

    A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in     perf_read_group().

    We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

    A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve     local privilege escalation.

    A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object     which is freed by another thread.

    We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

    A use-after-free issue was found in igmp_start_timer in net/ipv4/igmp.c in the network sub-component in     the Linux Kernel. This flaw allows a local user to observe a refcnt use-after-free issue when receiving an     igmp query packet, leading to a kernel information leak. (CVE-2024-0584)

  - SUNRPC: Fix RPC client cleaned up the freed pipefs dentries RPC client pipefs dentries cleanup is in     separated rpc_remove_pipedir() workqueue,which takes care about pipefs superblock locking. In some special     scenarios, when kernel frees the pipefs sb of the current client and immediately alloctes a new pipefs sb,     rpc_remove_pipedir function would misjudge the existence of pipefs sb which is not the one it used to     hold. As a result, the rpc_remove_pipedir would clean the released freed pipefs dentries. To fix this     issue, rpc_remove_pipedir should check whether the current pipefs sb is consistent with the original     pipefs sb.

远程主机上安装的内核版本低于 5.10.205-195.804。因此，会受到 ALAS2KERNEL-5.10-2024-045 公告中提及的多个漏洞影响。

    - 在 Linux 内核的 QXL 驱动程序中发现了一个争用情形，该情形会导致释放后使用问题。
    (CVE-2023-39198)

    在 Linux 内核 6.5.9 及之前的版本中发现问题。在 SQ 线程退出的竞争中，可能会发生 io_uring/fdinfo.c io_uring_show_fdinfo 空指针取消引用。(CVE-2023-46862)

    路由器在遇到太大而无法传输到下一跃点的 IPv6 数据包时，将向发送方返回“ICMP6 数据包过大 (PTB)”消息。发送方会缓存更新后的最大传输单元 (MTU)，以便了解在随后路由到同一主机时不要超过此值。

    在 6.3之前的 Linux 内核中，向缓存添加目标时，如果条目数超过阈值，则系统会对 IPv6 目标路由缓存执行垃圾回收。此垃圾回收操作会在保持锁定时检查缓存中的每个条目。在这些受影响的内核版本中，Pv6 ICMP6 PTB 消息洪流可造成高锁争夺和 CPU 使用率增加，从而发生拒绝服务情形。

    补丁通过使 IPv6 代码更接近 IPv4 代码（不存在此问题），向后移植 Linux 内核 6.3 中的垃圾回收改进功能。

    补丁：https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=af6d10345ca76670c1b7c37799f0d5576ccef277 (CVE-2023-52340)

    perf_event 的 read_size 可能溢出，导致 perf_read_group() 发生堆越界递增或写入。

    我们建议升级过去的提交 382c27f4ed28f803b1f1473ac2d8db0afc795a1b。(CVE-2023-6931)

    Linux 内核 ipv4 组件中存在一个释放后使用漏洞，攻击者可利用此漏洞实现本地特权提升。

    攻击者可利用争用情形导致定时器在由其他线程释放的 RCU 读取锁定对象上被错误注册。

    我们建议升级过去的提交 e2b706c691905fe78468c361aaabc719d0a496f1。(CVE-2023-6932)

    在 Linux 内核的网络子组件中，net/ipv4/igmp.c 的 igmp_start_timer 中发现了一个释放后使用问题。此缺陷可导致本地用户在接收 igmp 查询数据包时出现 refcnt 释放后使用问题，从而导致内核信息泄漏。(CVE-2024-0584)

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。

  - SUNRPC修复了 RPC 客户端清理了已释放的 pipefs dentries RPC 客户端 pipefs dentries 清理是在分隔的 rpc_remove_pipedir() 工作队列中进行的从而负责 pipefs 超级块锁定。在某些特殊情况下当内核释放当前客户端的 pipefs sb 并立即分配新的 pipefs sb 时rpc_remove_pipedir 函数将错误判断与之前保留的 pipefs sb 不同的存在性。因此rpc_remove_pipedir 将清除已释放的 pipefs dentry。要修复此问题rpc_remove_pipedir 应检查当前 pipefs sb 是否与原始 pipefs sb 一致。KASAN 可捕获此错误========================================== =============== [250.497700] BUGKASANdget_parent+0x195/0x200 中的 slab 释放后使用 [ 250.498315] 通过任务 kworker 读取 addr ffff88800a2ab804 处大小 4 的内容/0:18/106503 [ 250.500549] Workqueue事件 rpc_free_client_work [250.501001] 调用跟踪[ 250.502880] kasan_report+0xb6/0xf0 [ 250.503209] ? dget_parent+0x195/0x200 [250.503561] dget_parent+0x195/0x200 [ 250.503897] ? __pfx_rpc_clntdir_depopulate+0x10/0x10 [ 250.504384] rpc_rmdir_depopulate+0x1b/0x90 [ 250.504781] rpc_remove_client_dir+0xf5/0x150 [ 250.505195] rpc_free_client_work+0xe4/0x230 [ 250.505598] process_one_work+0x8ee/0x13b0 ... 22.039056分配任务 244[ 22.039390] kasan_save_stack+0x22/0x50 [ 22.039758] kasan_set_track+0x25/0x30 [ 22.040109]
