JFS image via local syscalls; JFS is a block filesystem (FS_REQUIRES_DEV, no FS_USERNS_MOUNT) and is not reachable from network packet processing.\nAC:L - A malicious image with corrupted dmap tree metadata (e.g. leafidx) reliably drives dbAdjTree past the real TREESIZE bound during ordinary free/alloc paths; success does not depend on races or uncontrolled system state.\nPR:L - After the crafted filesystem is mounted, an unprivileged local user with access to it can trigger the vulnerable free path through normal file operations (unlink/truncate/write); scoring PR:H would understate this reachable local-user scenario.\nUI:N - Exploitation is completed by the attacker's own filesystem operations on the mounted image; no additional interactive victim action is required at trigger time.\nS:U - Impact is confined to the host kernel's discretionary authority (local privilege escalation / kernel memory corruption); it does not cross a VM, IOMMU, or other security boundary.\nC:H - The bug performs an out-of-bounds read of dmt_stree before writing, and kernel OOB memory corruption of this form can be leveraged for arbitrary information disclosure.\nI:H - dbAdjTree performs an out-of-bounds write into adjacent kernel memory within the dmap metapage, which is exploitable memory corruption capable of control-flow hijacking or arbitrary write primitives.\nA:H - The OOB access can crash the kernel (UBSAN/KASAN reports and panic_on_warn in reproducers; related dbAdjTree reports include slab OOB/UAF), causing full availability loss." } ] } ], "affected": [ { "product":
