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.

CVE-2024-32936 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Chenyuan Yang discovered that the CEC driver driver in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2024-23848)
It was discovered that the JFS file system contained an out-of-bounds read
vulnerability when printing xattr debug information. A local attacker could
use this to cause a denial of service (system crash). (CVE-2024-40902)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- ARM64 architecture;
- MIPS architecture;
- PA-RI
