CVE-2024-26621 – mm: huge_memory: don't force huge page alignment on 32 bit
https://notcve.org/view.php?id=CVE-2024-26621
02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: mm: huge_memory: don't force huge page alignment on 32 bit commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries") caused two issues [1] [2] reported on 32 bit system or compat userspace. It doesn't make too much sense to force huge page alignment on 32 bit system due to the constrained virtual address space.

CVE-2024-26620 – s390/vfio-ap: always filter entire AP matrix
https://notcve.org/view.php?id=CVE-2024-26620
29 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: always filter entire AP matrix The vfio_ap_mdev_filter_matrix function is called whenever a new adapter or domain is assigned to the mdev. The purpose of the function is to update the guest's AP configuration by filtering the matrix of adapters and domains assigned to the mdev. When an adapter or domain is assigned, only the APQNs associated with the APID of the new adapter or APQI of the new domain are inspected. If an APQN d... • https://git.kernel.org/stable/c/48cae940c31d2407d860d87c41d5f9871c0521db •

CVE-2024-26618 – arm64/sme: Always exit sme_alloc() early with existing storage
https://notcve.org/view.php?id=CVE-2024-26618
29 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: arm64/sme: Always exit sme_alloc() early with existing storage When sme_alloc() is called with existing storage and we are not flushing we will always allocate new storage, both leaking the existing storage and corrupting the state. Fix this by separating the checks for flushing and for existing storage as we do for SVE. Callers that reallocate (eg, due to changing the vector length) should call sme_free() themselves.
