No network protocol handler is involved.\nAC:L - The attacker controls both sides of the race \u2014 one thread frees or scans blocks in a group to trigger corruption detection under the group lock while another thread issues a goal-hinted allocation into the same group, and the racing thread spins on ext4_lock_group() for the whole (long) critical section of the corruption detector, so the window is easily won and retried indefinitely.\nPR:L - Only an ordinary unprivileged local account is needed \u2014 any writable directory on an ext4 filesystem (e.g. /tmp or a home directory) lets the attacker drive both the allocation and the block-freeing paths. No capability or userns trick is required.\nUI:N - Exploitation happens through the attacker\u0027s own concurrent file I/O on an already-mounted filesystem; no victim action such as mounting an image or opening a file is required.\nS:U - The impact is confined to the kernel/OS security authority \u2014 filesystem metadata corruption and kernel crashes \u2014 with no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - Allocating from a group whose bitmap is known-inconsistent hands out blocks that are still in use by other inodes, so the attacker\u0027s file can be read back containing another user\u0027s on-disk data \u2014 an unbounded disclosure of arbitrary filesystem content.\nI:H - The same double-allocation lets the attacker\u0027s writes overwrite other users\u0027 file data and ext4 metadata, and the double `percpu_counter_sub` on s_freeclusters_counter corrupts global free-space accounting, giving arbitrary on-disk data modification.\nA:H - The path reaches the divide-by-zero in mb_update_avg_fragment_size() and multiple BUG_ON()s in mb_mark_used() on an inconsistent buddy, and ext4_mb_mark_diskspace_used()\u0027s \"overlap fs metadata\" ext4_error() forces the filesystem read-only (or panics with errors=panic), plus free-cluster underflow causes filesystem-wide ENOSPC."

No network protocol handler is involved.\nAC:L - The attacker controls both sides of the race \u2014 one thread frees or scans blocks in a group to trigger corruption detection under the group lock while another thread issues a goal-hinted allocation into the same group, and the racing thread spins on ext4_lock_group() for the whole (long) critical section of the corruption detector, so the window is easily won and retried indefinitely.\nPR:L - Only an ordinary unprivileged local account is needed \u2014 any writable directory on an ext4 filesystem (e.g. /tmp or a home directory) lets the attacker drive both the allocation and the block-freeing paths. No capability or userns trick is required.\nUI:N - Exploitation happens through the attacker\u0027s own concurrent file I/O on an already-mounted filesystem; no victim action such as mounting an image or opening a file is required.\nS:U - The impact is confined to the kernel/OS security authority \u2014 filesystem metadata corruption and kernel crashes \u2014 with no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - Allocating from a group whose bitmap is known-inconsistent hands out blocks that are still in use by other inodes, so the attacker\u0027s file can be read back containing another user\u0027s on-disk data \u2014 an unbounded disclosure of arbitrary filesystem content.\nI:H - The same double-allocation lets the attacker\u0027s writes overwrite other users\u0027 file data and ext4 metadata, and the double `percpu_counter_sub` on s_freeclusters_counter corrupts global free-space accounting, giving arbitrary on-disk data modification.\nA:H - The path reaches the divide-by-zero in mb_update_avg_fragment_size() and multiple BUG_ON()s in mb_mark_used() on an inconsistent buddy, and ext4_mb_mark_diskspace_used()\u0027s \"overlap fs metadata\" ext4_error() forces the filesystem read-only (or panics with errors=panic), plus free-cluster underflow causes filesystem-wide ENOSPC."
