Title
jffs2: prevent xattr node from overflowing the eraseblock
Summary
In the Linux kernel, the following vulnerability has been resolved: jffs2: prevent xattr node from overflowing the eraseblock Add a check to make sure that the requested xattr node size is no larger than the eraseblock minus the cleanmarker. Unlike the usual inode nodes, the xattr nodes aren't split into parts and spread across multiple eraseblocks, which means that a xattr node must not occupy more than one eraseblock. If the requested xattr value is too large, the xattr node can spill onto the next eraseblock, overwriting the nodes and causing errors such as: jffs2: argh. node added in wrong place at 0x0000b050(2) jffs2: nextblock 0x0000a000, expected at 0000b00c jffs2: error: (823) do_verify_xattr_datum: node CRC failed at 0x01e050, read=0xfc892c93, calc=0x000000 jffs2: notice: (823) jffs2_get_inode_nodes: Node header CRC failed at 0x01e00c. {848f,2fc4,0fef511f,59a3d171} jffs2: Node at 0x0000000c with length 0x00001044 would run over the end of the erase block jffs2: Perhaps the file system was created with the wrong erase size? jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000010: 0x1044 instead This breaks the filesystem and can lead to KASAN crashes such as: BUG: KASAN: slab-out-of-bounds in jffs2_sum_add_kvec+0x125e/0x15d0 Read of size 4 at addr ffff88802c31e914 by task repro/830 CPU: 0 PID: 830 Comm: repro Not tainted 6.9.0-rc3+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.16.3-1-1 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0xc6/0x120 print_report+0xc4/0x620 ? __virt_addr_valid+0x308/0x5b0 kasan_report+0xc1/0xf0 ? jffs2_sum_add_kvec+0x125e/0x15d0 ? jffs2_sum_add_kvec+0x125e/0x15d0 jffs2_sum_add_kvec+0x125e/0x15d0 jffs2_flash_direct_writev+0xa8/0xd0 jffs2_flash_writev+0x9c9/0xef0 ? __x64_sys_setxattr+0xc4/0x160 ? do_syscall_64+0x69/0x140 ? entry_SYSCALL_64_after_hwframe+0x76/0x7e [...] Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

There is no network-facing consumer of this path in a realistic JFFS2 (embedded flash) deployment.\nAC:L - A single setxattr call with a value larger than the eraseblock deterministically triggers the over-allocation and the overflowing write \u2014 no race, no memory-layout dependency, and the attacker chooses the value size. The only precondition is an eraseblock of 64K or less, which is the standard geometry for the NOR flash JFFS2 targets (the public reproducer used a 4K eraseblock).\nPR:L - The user.* xattr handler is registered unconditionally with CONFIG_JFFS2_FS_XATTR and the VFS only requires write permission on the target inode, so any unprivileged local account with a writable file or directory on the JFFS2 mount can reach do_jffs2_setxattr. No capability check exists anywhere on the path.\nUI:N - On the affected class of systems the JFFS2 volume is the rootfs or data partition mounted automatically at boot, so the attacker acts alone with no victim action required. The vulnerable syscall path executes entirely in the attacker\u0027s own context.\nS:U - The corruption is confined to the kernel\u0027s own memory and the flash medium it manages, within a single security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The wrapped write offset indexes c-\u003eblocks far out of bounds, producing a KASAN-confirmed slab out-of-bounds read and subsequent wild-pointer dereferences of attacker-groomable heap data. The corrupted on-media node layout also causes later reads to parse data at wrong offsets, exposing neighbouring nodes belonging to other users\u0027 and root-owned files.\nI:H - The oversized node is written past the end of its eraseblock, overwriting nodes of unrelated files \u2014 on a JFFS2 rootfs that means arbitrary system data an unprivileged user cannot otherwise touch. The resulting free_size underflow drives jffs2_link_node_ref() to write through a jeb-\u003elast_node pointer read from out-of-bounds heap memory, a kernel-memory write primitive suitable for control-flow hijack.\nA:H - The path reaches wild-pointer dereferences and an explicit BUG() in jffs2_link_node_ref(), panicking the kernel. Worse, the damage is persistent: the commit log shows the volume subsequently fails eraseblock scanning at mount, permanently bricking an embedded device whose rootfs is JFFS2."
