CVSS V3.0分值：
BaseScore：9.8 Critical
Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:clk: bcm: dvp: Assign ->num before accessing ->hwsCommit f316cdff8d67 ( clk: Annotate struct clk_hw_onecell_data with__counted_by ) annotated the hws member of struct clk_hw_onecell_data with __counted_by, which informs the bounds sanitizer about the numberof elements in hws, so that it can warn when hws is accessed out ofbounds. As noted in that change, the __counted_by member must beinitialized with the number of elements before the first array accesshappens, otherwise there will be a warning from each access prior to theinitialization because the number of elements is zero. This occurs inclk_dvp_probe() due to ->num being assigned after ->hws has beenaccessed: UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-bcm2711-dvp.c:59:2 index 0 is out of range for type struct clk_hw *[] __counted_by(num) (aka struct clk_hw *[] )Move the ->num initialization to before the first access of ->hws, whichclears up the warning.

CVE-2024-39462

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

clk: bcm: dvp: Assign ->num before accessing ->hws

Commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with
__counted_by") annotated the hws member of 'struct clk_hw_onecell_data'
with __counted_by, which informs the bounds sanitizer about the number
of elements in hws, so that it can warn when hws is accessed out of
bounds. As noted in that change, the __counted_by member must be
initialized with the number of elements before the first array access
happens, otherwise there will be a warning from each access prior to the
initialization because the number of elements is zero. This occurs in
clk_dvp_probe() due to ->num being assigned after ->hws has been
accessed:

UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-bcm2711-dvp.c:59:2
index 0 is out of range for type 'struct clk_hw *[] __counted_by(num)' (aka 'struct clk_hw *[]')

Move the ->num initialization to before the first access of ->hws, which
clears up the warning.

The Linux kernel CVE team has assigned CVE-2024-39462 to this issue.

CVE-2024-39462

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

clk: bcm: dvp: Assign ->num before accessing ->hws

Commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with
__counted_by") annotated the hws member of 'struct clk_hw_onecell_data'
with __counted_by, which informs the bounds sanitizer about the number
of elements in hws, so that it can warn when hws is accessed out of
bounds. As noted in that change, the __counted_by member must be
initialized with the number of elements before the first array access
happens, otherwise there will be a warning from each access prior to the
initialization because the number of elements is zero. This occurs in
clk_dvp_probe() due to ->num being assigned after ->hws has been
accessed:

UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-bcm2711-dvp.c:59:2
index 0 is out of range for type 'struct clk_hw *[] __counted_by(num)' (aka 'struct clk_hw *[]')

Move the ->num initialization to before the first access of ->hws, which
clears up the warning.

The Linux kernel CVE team has assigned CVE-2024-39462 to this issue.
