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，以下漏洞已得到修复： spi: amlogic-spisg：确保 clk_init_data 被完全初始化 clk_init_data 结构体包含若干互斥的成员变量，用于通过不同方法指定时钟的可能父时钟，这导致驱动程序只需初始化其所需的成员。然而，若未初始化所有成员，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 配置时才会暴露出来。 函数 aml_spisg_clk_init() 填充了 i

Vulnerability Title
spi: amlogic-spisg: 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:
spi: amlogic-spisg: 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.
aml_spisg_clk_init() fills in init.parent_data, and assumes that
init.parent_names 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.
