UBUNTU-CVE-2025-68358

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix racy bitfield write in btrfsclearspaceinfofull From the memory-barriers.txt document regarding memory barrier ordering guarantees: These guarantees do not apply to bitfields, because compilers often generate code to...

CVE-2023-53989

In the Linux kernel, the following vulnerability has been resolved: arm64: mm: fix VA-range sanity check Both createmappingnoalloc and updatemappingprot sanity-check their 'virt' parameter, but the check itself doesn't make much sense. The condition used today appears to be a historical accident...

CVE-2023-54042

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Fix VAS mm use after free The refcount on mm is dropped before the coprocessor is detached...

CVE-2023-54042

CVE-2023-54042 affects the Linux kernel on powerpc/64s. The issue is a use-after-free involving VAS memory management where the refcount on mm is dropped before detaching the coprocessor, potentially leading to use-after-free conditions. The vulnerability was fixed in the kernel by correcting the...

CVE-2023-54042 powerpc/64s: Fix VAS mm use after free

CVE-2023-54034

The CVE-2023-54034 issue affects the Linux kernel iommufd path where vfio_iommu_type1_info is copied to user space. The root cause is a missing zero initialization: most of the struct is copied with copy_from_user(), but minsz is smaller than the struct by 8 bytes, leaving the padding uninitializ...

CVE-2023-53989

CVE-2023-53989 (Linux kernel, arm64) The issue is a faulty VA-range sanity check in mm/create_mapping_noalloc() and mm/update_mapping_prot() that could incorrectly trigger on certain regions. The historical condition ((virt >= PAGE_END) && (virt

CVE-2025-68358

CVE-2025-68358 (Linux kernel, btrfs) : A race condition was fixed in btrfs_clear_space_info_full() that updated bitfield members (full, chunk_alloc, flush) without holding the space_info lock, risking corruption of adjacent fields due to non-atomic read-modify-write sequences on bitfields. The fi...

CVE-2025-68356 gfs2: Prevent recursive memory reclaim

In the Linux kernel, the following vulnerability has been resolved: gfs2: Prevent recursive memory reclaim Function newinode returns a new inode with inode-imapping-gfpmask set to GFPHIGHUSERMOVABLE. This value includes the GFPFS flag, so allocations in that address space can recurse into...
