Rocky Linux 9.6 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.6：CLSA-2026：1782155469 2公告中提及的多个漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：udf: Fix preallocation discarding at indirect extent boundary When preallocation extent is the first one in the extent block, the code would corrupt extent tree header instead. Fix the problem and use udf_delete_aext() for deleting extent to avoid some code duplication. (CVE-2022-48946)

  - 已修复 Linux 内核中的下列漏洞：xen/privcmd: fix error exit of privcmd_ioctl_dm_op() The error exit of privcmd_ioctl_dm_op() is calling unlock_pages() potentially with pages being NULL, leading to a NULL dereference. Additionally lock_pages() doesn't check for pin_user_pages_fast() having been completely successful, resulting in potentially not locking all pages into memory. This could result in sporadic failures when using the related memory in user mode. Fix all of that by calling unlock_pages() always with the real number of pinned pages, which will be zero in case pages being NULL, and by checking the number of pages pinned by pin_user_pages_fast() matching the expected number of pages. (CVE-2022-49989)

  - 已修复 Linux 内核中的下列漏洞：platform/x86: mxm-wmi: fix memleak in mxm_wmi_call_mx[ds|mx]() The ACPI buffer memory (out.pointer) returned by wmi_evaluate_method() is not freed after the call, so it leads to memory leak. The method results in ACPI buffer is not used, so just pass NULL to wmi_evaluate_method() which fixes the memory leak. (CVE-2022-50521)

  - 已修复 Linux 内核中的下列漏洞：tracing: Make sure trace_printk() can output as soon as it can be used Currently trace_printk() can be used as soon as early_trace_init() is called from start_kernel(). But if a crash happens, and ftrace_dump_on_oops is set on the kernel command line, all you get will be: [ 0.456075] <idle>-0 0dN.2. 347519us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 353141us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 358684us : Unknown type 6 This is because the trace_printk() event (type 6) hasn't been registered yet. That gets done via an early_initcall(), which may be early, but not early enough. Instead of registering the trace_printk() event (and other ftrace events, which are not trace events) via an early_initcall(), have them registered at the same time that trace_printk() can be used. This way, if there is a crash before early_initcall(), then the trace_printk()s will actually be useful. (CVE-2023-53007)
