Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： hwmon: (ltc4282) 确保 clk_init_data 结构体被完全初始化 clk_init_data 结构体包含多个互斥的成员变量，用于以不同方式指定时钟的可能父时钟。驱动程序通常只需初始化其所需的那些成员。然而，若未对所有成员进行初始化，可能会引发细微问题，这些问题仅在启用 CONFIG_INIT_STACK_ALL_PATTERN 或 CONFIG_INIT_STACK_NONE 配置选项时才会暴露出来。 函数 ltc428_clk_provider_se

Vulnerability Title
hwmon: (ltc4282) Make sure clk_init_data is fully initialized
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (ltc4282) Make sure clk_init_data is fully initialized
The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need. However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.
ltc428_clk_provider_setup() does not fill in any parent clocks, and
assumes that init.num_parents is NULL. However, the latter in
uninitialized, and thus may cause a crash.
Make sure all members are fully initialized, to fix such bugs, and to
avoid future breakage when converting drivers to a different method for
specifying the parents.
