In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb.c: fix UAF of vma in hugetlb fault pathway
Syzbot reports a UAF in hugetlb_fault(). This happens because
vmf_anon_prepare() could drop the per-VMA lock and allow the current VMA
to be freed before hugetlb_vma_unlock_read() is called.
We can fix this by using a modified version of vmf_anon_prepare() that
doesn't release the VMA lock on failure, and then release it ourselves
after hugetlb_vma_unlock_read().

CVE-2024-47738 Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)
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:
