This causes the #DB handler\n(exc_debug_kernel()) to issue a warning because single-step is used outside the\nentry_SYSENTER_compat() function.\n\nTo address this issue, entry_SYSENTER_compat() should use CLEAR_BRANCH_HISTORY\nafter making sure the TF flag is cleared.\n\nThe problem can be reproduced with the following sequence:\n\n  $ cat sysenter_step.c\n  int main()\n  { asm(\"pushf; pop %ax; bts $8,%ax; push %ax; popf; sysenter\"); }\n\n  $ gcc -o sysenter_step sysenter_step.c\n\n  $ ./sysenter_step\n  Segmentation fault (core dumped)\n\nThe program is expected to crash, and the #DB handler will issue a warning.\n\nKernel log:\n\n  WARNING: CPU: 27 PID: 7000 at arch/x86/kernel/traps.c:1009 exc_debug_kernel+0xd2/0x160\n  ...\n  RIP: 0010:exc_debug_kernel+0xd2/0x160\n  ...\n  Call Trace:\n  \u003c#DB\u003e\n   ? show_regs+0x68/0x80\n   ? __warn+0x8c/0x140\n   ? exc_debug_kernel+0xd2/0x160\n   ? report_bug+0x175/0x1a0\n   ? handle_bug+0x44/0x90\n   ? exc_invalid_op+0x1c/0x70\n   ? asm_exc_invalid_op+0x1f/0x30\n   ? exc_debug_kernel+0xd2/0x160\n   exc_debug+0x43/0x50\n   asm_exc_debug+0x1e/0x40\n  RIP: 0010:clear_bhb_loop+0x0/0xb0\n  ...\n  \u003c/#DB\u003e\n  \u003cTASK\u003e\n   ? entry_SYSENTER_compat_after_hwframe+0x6e/0x8d\n  \u003c/TASK\u003e\n\n  [ bp: Massage commit message. ]"

It introduced IDR to maintain the memcg ID\nspace.  The IDR depends on external synchronization mechanisms for\nmodifications.  For the mem_cgroup_idr, the idr_alloc() and idr_replace()\nhappen within css callback and thus are protected through cgroup_mutex\nfrom concurrent modifications.  However idr_remove() for mem_cgroup_idr\nwas not protected against concurrency and can be run concurrently for\ndifferent memcgs when they hit their refcnt to zero.  Fix that.\n\nWe have been seeing list_lru based kernel crashes at a low frequency in\nour fleet for a long time.  These crashes were in different part of\nlist_lru code including list_lru_add(), list_lru_del() and reparenting\ncode.  Upon further inspection, it looked like for a given object (dentry\nand inode), the super_block\u0027s list_lru didn\u0027t have list_lru_one for the\nmemcg of that object.  The initial suspicions were either the object is\nnot allocated through kmem_cache_alloc_lru() or somehow\nmemcg_list_lru_alloc() failed to allocate list_lru_one() for a memcg but\nreturned success.  No evidence were found for these cases.\n\nLooking more deeply, we started seeing situations where valid memcg\u0027s id\nis not present in mem_cgroup_idr and in some cases multiple valid memcgs\nhave same id and mem_cgroup_idr is pointing to one of them.  So, the most\nreasonable explanation is that these situations can happen due to race\nbetween multiple idr_remove() calls or race between\nidr_alloc()/idr_replace() and idr_remove().  These races are causing\nmultiple memcgs to acquire the same ID and then offlining of one of them\nwould cleanup list_lrus on the system for all of them.  Later access from\nother memcgs to the list_lru cause crashes due to missing list_lru_one."

These variables were\npreviously assumed to be null at line 922, but they were used later in\nthe code without checking if they were null. This could potentially lead\nto a null pointer dereference, which would cause a crash.\n\nThe null checks ensure that \u0027stream\u0027 and \u0027plane\u0027 are not null before\nthey are used, preventing potential crashes.\n\nFixes the below static smatch checker:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:938 dcn30_apply_idle_power_optimizations() error: we previously assumed \u0027stream\u0027 could be null (see line 922)\ndrivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:940 dcn30_apply_idle_power_optimizations() error: we previously assumed \u0027plane\u0027 could be null (see line 922)"

There is no network or adjacent-network path into the f2fs garbage collector.\nAC:L - Setting `F2FS_INLINE_DATA` in the inode while leaving a valid blkaddr in its direct node is a direct on-disk edit, and `is_alive()` plus the phase-4 checks then pass deterministically; background GC is enabled by default and the attacker can size the image so free sections run low, forcing migration on demand. No race, timing, or memory-layout condition outside the attacker\u0027s control is involved.\nPR:L - An unprivileged local user gets the crafted image mounted through loop devices or desktop/kiosk/Android automounters (udisks2, systemd, vold), and no capability check exists on the GC or writeback path that follows. This matches how the repo scores equivalent f2fs on-disk validation bugs (CVE-2024-47690, CVE-2024-56692).\nUI:N - In the automount/loop scenario the attacker performs the mount itself and the background GC kthread plus the flusher worker drive the crash asynchronously. No separate victim action is required.\nS:U - The BUG_ON panic, the stuck page/node-page locks, and the corrupted inode block-pointer array all remain inside the kernel\u0027s own security authority and the mounted filesystem. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - On the non-`CONFIG_F2FS_CHECK_FS` path the WARN is non-fatal and the inode\u0027s `i_addr[]` array is replaced with attacker-chosen 32-bit values that f2fs subsequently dereferences as block addresses in `f2fs_get_dnode_of_data()`/`f2fs_map_blocks()`, allowing in-range blocks belonging to other files on the volume to be read back. The persisted metadata corruption therefore yields cross-file content disclosure, not merely a crash.\nI:H - `memcpy_from_page(inline_data_addr(inode, dn.inode_page), page, 0, MAX_INLINE_DATA(inode))` stomps roughly the whole `i_addr[]` block-pointer array of the inode with the contents of an unrelated data block the attacker controls, and `set_page_dirty(dn.inode_page)` writes that back to disk. The result is attacker-controlled corruption of filesystem metadata that the kernel only flags with `SBI_NEED_FSCK` rather than rejecting.\nA:H - With `CONFIG_F2FS_CHECK_FS` the reported failure is an outright `kernel BUG at fs/f2fs/inline.c:258` inside the writeback kworker, which dies holding the data page lock and the locked inode node page so every subsequent access to that inode and the bdi flusher deadlocks; without it the `WARN_ON` is fatal under `panic_on_warn` and otherwise repeats on every GC pass while marking the filesystem as needing fsck."

It also assumes that the caller will make the appropriate\n *  permission checks.\n\nnfsd_setattr() does do permissions checking via fh_verify() and\nnfsd_permission(), but those don\u0027t do all the same permissions checks\nthat are done by security_inode_setxattr() and its related LSM hooks do.\n\nSince nfsd_setattr() is the only consumer of security_inode_setsecctx(),\nsimplest solution appears to be to replace the call to\n__vfs_setxattr_noperm() with a call to __vfs_setxattr_locked().  This\nfixes the above issue and has the added benefit of causing nfsd to\nrecall conflicting delegations on a file when a client tries to change\nits security label."

Per kernel CNA guidance nfsd bugs are Network.\nAC:L - A single, fully attacker-controlled SETATTR RPC deterministically writes the label; there is no race, no memory-layout dependency, and no retry needed. The only precondition is the standard labeled-NFS deployment (CONFIG_NFSD_V4_SECURITY_LABEL plus the `security_label` export option), which is the configuration being scored.\nPR:N - The essence of the bug is that all permission checks are skipped: nfsd_permission() is invoked with an effective mask of 0 and the LSM relabel/CAP_MAC_ADMIN/ownership checks never run, so any asserted AUTH_SYS uid works \u2014 including the squashed anonymous uid. The attacker needs no account or credential on the server; export IP filtering and the reserved-port `secure` check are network-level controls, not privileges on the vulnerable component.\nUI:N - The attacker issues the RPC directly against the server; no administrator or user on the server has to open a file, mount anything, or take any action.\nS:U - The bypassed checks and the corrupted security labels are both enforced and consumed by the same kernel/LSM security authority on the NFS server; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Arbitrary relabeling defeats the MAC confidentiality controls that are the primary protection on such systems \u2014 an MLS-labeled file can be dropped to a lower level, or a protected file relabeled to a type readable by an untrusted or attacker-influenced domain, and the httpd_sys_script_exec_t-style relabel yields code execution on the server with arbitrary read.\nI:H - An unauthenticated client can write arbitrary SELinux contexts or Smack labels onto any file in the export, bypassing inode_owner_or_capable(), FILE__RELABELFROM/RELABELTO policy, CAP_MAC_ADMIN, immutable/append-only flags, and root squashing \u2014 a complete compromise of security-critical metadata that can be escalated to code execution on the server.\nA:H - Relabeling files to a type or invalid context that legitimate confined domains cannot access denies those services their data and breaks them, and the same primitive escalates to code execution allowing the server to be rendered inoperable."

No network or physical component is involved.\nAC:L - The off-by-one is deterministic \u2014 allocate a buffer, mmap it at full size, grow it with mremap (unblocked before v6.8), then touch the page at offset `pagecount`. Buffer size is attacker-chosen, so the slab layout used to control the adjacent `struct page *` can be groomed reliably.\nPR:L - No capability check exists anywhere on the path (`dma_heap_open`/`dma_heap_ioctl_allocate`/`cma_heap_allocate`); only DAC permission on the heap device node is needed, which on the dominant deployment for CMA heaps (Android/embedded ARM) is granted to ordinary unprivileged app and media processes.\nUI:N - The attacking process performs every step itself \u2014 open, ioctl, mmap, mremap, memory access. No victim action or cooperation is required.\nS:U - The corruption and the resulting privilege gain are entirely within the kernel\u0027s own security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - Beyond the 8-byte out-of-bounds slab read, the handler installs the forged `struct page` into the faulting process\u0027s page tables, giving userspace a direct read mapping of an arbitrary physical page \u2014 arbitrary kernel and cross-process memory disclosure.\nI:H - The VMA is `MAP_SHARED` with no `page_mkwrite`, so `finish_fault()` installs a writable PTE for the arbitrary page, yielding an arbitrary physical-memory write; `get_page()` additionally increments a refcount at an attacker-influenced address. Both are readily leveraged into control-flow hijack and root.\nA:H - Dereferencing an out-of-bounds `struct page *` and inserting a bogus PFN into a mapping causes oops/panic and refcount corruption of unrelated pages, and the attacker can repeat it at will."
