Title
nilfs2: fix potential kernel bug due to lack of writeback flag waiting
Summary
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential kernel bug due to lack of writeback flag waiting Destructive writes to a block device on which nilfs2 is mounted can cause a kernel bug in the folio/page writeback start routine or writeback end routine (__folio_start_writeback in the log below): kernel BUG at mm/page-writeback.c:3070! Oops: invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI ... RIP: 0010:__folio_start_writeback+0xbaa/0x10e0 Code: 25 ff 0f 00 00 0f 84 18 01 00 00 e8 40 ca c6 ff e9 17 f6 ff ff e8 36 ca c6 ff 4c 89 f7 48 c7 c6 80 c0 12 84 e8 e7 b3 0f 00 90 <0f> 0b e8 1f ca c6 ff 4c 89 f7 48 c7 c6 a0 c6 12 84 e8 d0 b3 0f 00 ... Call Trace: <TASK> nilfs_segctor_do_construct+0x4654/0x69d0 [nilfs2] nilfs_segctor_construct+0x181/0x6b0 [nilfs2] nilfs_segctor_thread+0x548/0x11c0 [nilfs2] kthread+0x2f0/0x390 ret_from_fork+0x4b/0x80 ret_from_fork_asm+0x1a/0x30 </TASK> This is because when the log writer starts a writeback for segment summary blocks or a super root block that use the backing device's page cache, it does not wait for the ongoing folio/page writeback, resulting in an inconsistent writeback state. Fix this issue by waiting for ongoing writebacks when putting folios/pages on the backing device into writeback state.

There is no remote or adjacent-network path into fs/nilfs2/segment.c.\nAC:L - Although the flaw is a race between the block-device writeback path and the nilfs2 log writer, the attacker controls both sides \u2014 issuing the buffered device writes plus sync/fsync, and driving segment construction via filesystem I/O \u2014 and can retry in a tight loop until it lands. The fix author reproduced it deterministically with ordinary destructive device writes.\nPR:L - Only an unprivileged local account with write access to the device node is needed (disk-group service accounts, logind/udisks-ACL\u0027d removable media on desktops and kiosks, or a container granted the device); no CAP_SYS_ADMIN is required for the triggering writes themselves.\nUI:N - Once a nilfs2 filesystem is mounted \u2014 a routine system state, not an attacker-supplied crafted image \u2014 the attacker acts entirely alone. No victim action is needed at any point in the attack.\nS:U - The corruption is confined to kernel page-cache state and the kernel\u0027s own memory; no VM, IOMMU, or sandbox boundary is crossed. Impact and vulnerable component share the same security authority.\nC:H - Premature clearing of PG_writeback removes the only protection keeping the folio alive under in-flight I/O (bio_add_folio takes no page reference), so the page can be truncated/reclaimed and reused while nilfs2\u0027s write bio still DMAs from it \u2014 leaking arbitrary reused kernel page contents onto the block device, which the attacker can read back.\nI:H - The same broken invariant makes nilfs2\u0027s completion handler call folio_end_writeback() on freed folio memory, a use-after-free write into a reclaimed and potentially heap-sprayed object, which is the classic primitive for control-flow hijacking. Filesystem metadata is additionally written from a page concurrently mutated by another writer.\nA:H - The documented outcome is a kernel BUG()/oops in the segctor kthread (mm/page-writeback.c), and on non-DEBUG_VM kernels the XOR in __folio_end_writeback re-sets PG_writeback on an idle folio, producing permanently hung unkillable tasks in folio_wait_writeback() plus writeback-accounting skew that stalls system-wide dirty throttling."
