[PATCH OLK-6.6] NFSD: free copynotify stateid in nfs4_free_ol_stateid()

From: Olga Kornievskaia <okorniev(a)redhat.com> stable inclusion from stable-v6.6.117 commit 29fbb3ad4018ca2b0988fbac76f4c694cc6d7e66 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDB6RK CVE: CVE-2025-40273 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4aa17144d5abc3c756883e3a010246f0dba8b468 upstream. Typically copynotify stateid is freed either when parent's stateid is being close/freed or in nfsd4_laundromat if the stateid hasn't been used in a lease period. However, in case when the server got an OPEN (which created a parent stateid), followed by a COPY_NOTIFY using that stateid, followed by a client reboot. New client instance while doing CREATE_SESSION would force expire previous state of this client. It leads to the open state being freed thru release_openowner-> nfs4_free_ol_stateid() and it finds that it still has copynotify stateid associated with it. We currently print a warning and is triggerred WARNING: CPU: 1 PID: 8858 at fs/nfsd/nfs4state.c:1550 nfs4_free_ol_stateid+0xb0/0x100 [nfsd] This patch, instead, frees the associated copynotify stateid here. If the parent stateid is freed (without freeing the copynotify stateids associated with it), it leads to the list corruption when laundromat ends up freeing the copynotify state later.

[PATCH OLK-5.10] vfs: Don't leak disconnected dentries on umount
by Zizhi Wo 08 Dec '25

08 Dec '25

From: Jan Kara <jack(a)suse.cz> stable inclusion from stable-v5.10.246 commit 20863bb7fbb016379f8227122edfabc5c799bc79 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID4A7Q CVE: CVE-2025-40105 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 56094ad3eaa21e6621396cc33811d8f72847a834 ] When user calls open_by_handle_at() on some inode that is not cached, we will create disconnected dentry for it. If such dentry is a directory, exportfs_decode_fh_raw() will then try to connect this dentry to the dentry tree through reconnect_path(). It may happen for various reasons (such as corrupted fs or race with rename) that the call to lookup_one_unlocked() in reconnect_one() will fail to find the dentry we are trying to reconnect and instead create a new dentry under the parent. Now this dentry will not be marked as disconnected although the parent still may well be disconnected (at least in case this inconsistency happened because the fs is corrupted and .. doesn't point to the real parent directory). This creates inconsistency in disconnected flags but AFAICS it was mostly harmless. At least until commit f1ee616214cb ("VFS: don't keep disconnected dentries on d_anon") which removed adding of most disconnected dentries to sb->s_anon list. Thus after this commit cleanup of disconnected dentries implicitely relies on the fact that dput() will immediately reclaim such dentries. However when some leaf dentry isn't marked as disconnected, as in the scenario described above, the reclaim doesn't happen and the dentries are "leaked". Memory reclaim can eventually reclaim them but otherwise they stay in memory and if umount comes first, we hit infamous "Busy inodes after unmount" bug. Make sure all dentries created under a disconnected parent are marked as disconnected as well.

[PATCH OLK-5.10] fs/proc: fix uaf in proc_readdir_de()

From: Wei Yang <albinwyang(a)tencent.com> stable inclusion from stable-v5.10.247 commit c81d0385500446efe48c305bbb83d47f2ae23a50 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDB6QZ CVE: CVE-2025-40271 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 895b4c0c79b092d732544011c3cecaf7322c36a1 upstream. Pde is erased from subdir rbtree through rb_erase(), but not set the node to EMPTY, which may result in uaf access. We should use RB_CLEAR_NODE() set the erased node to EMPTY, then pde_subdir_next() will return NULL to avoid uaf access. We found an uaf issue while using stress-ng testing, need to run testcase getdent and tun in the same time. The steps of the issue is as follows: 1) use getdent to traverse dir /proc/pid/net/dev_snmp6/, and current pde is tun3; 2) in the [time windows] unregister netdevice tun3 and tun2, and erase them from rbtree. erase tun3 first, and then erase tun2. the pde(tun2) will be released to slab; 3) continue to getdent process, then pde_subdir_next() will return pde(tun2) which is released, it will case uaf access.

[PATCH OLK-5.10] fs: Prevent file descriptor table allocations exceeding INT_MAX
by Zizhi Wo 08 Dec '25

08 Dec '25

From: Sasha Levin <sashal(a)kernel.org> stable inclusion from stable-v5.10.241 commit f95638a8f22eba307dceddf5aef9ae2326bbcf98 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICXMCD CVE: CVE-2025-39756 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 04a2c4b4511d186b0fce685da21085a5d4acd370 upstream. When sysctl_nr_open is set to a very high value (for example, 1073741816 as set by systemd), processes attempting to use file descriptors near the limit can trigger massive memory allocation attempts that exceed INT_MAX, resulting in a WARNING in mm/slub.c: WARNING: CPU: 0 PID: 44 at mm/slub.c:5027 __kvmalloc_node_noprof+0x21a/0x288 This happens because kvmalloc_array() and kvmalloc() check if the requested size exceeds INT_MAX and emit a warning when the allocation is not flagged with __GFP_NOWARN. Specifically, when nr_open is set to 1073741816 (0x3ffffff8) and a process calls dup2(oldfd, 1073741880), the kernel attempts to allocate: - File descriptor array: 1073741880 * 8 bytes = 8,589,935,040 bytes - Multiple bitmaps: ~400MB - Total allocation size: > 8GB (exceeding INT_MAX = 2,147,483,647) Reproducer: 1. Set /proc/sys/fs/nr_open to 1073741816: # echo 1073741816 > /proc/sys/fs/nr_open 2. Run a program that uses a high file descriptor: #include <unistd.h> #include <sys/resource.h> int main() { struct rlimit rlim = {1073741824, 1073741824}; setrlimit(RLIMIT_NOFILE, &rlim); dup2(2, 1073741880); // Triggers the warning return 0; } 3. Observe WARNING in dmesg at mm/slub.c:5027 systemd commit a8b627a introduced automatic bumping of fs.nr_open to the maximum possible value. The rationale was that systems with memory control groups (memcg) no longer need separate file descriptor limits since memory is properly accounted. However, this change overlooked that: 1. The kernel's allocation functions still enforce INT_MAX as a maximum size regardless of memcg accounting 2. Programs and tests that legitimately test file descriptor limits can inadvertently trigger massive allocations 3. The resulting allocations (>8GB) are impractical and will always fail systemd's algorithm starts with INT_MAX and keeps halving the value until the kernel accepts it. On most systems, this results in nr_open being set to 1073741816 (0x3ffffff8), which is just under 1GB of file descriptors. While processes rarely use file descriptors near this limit in normal operation, certain selftests (like tools/testing/selftests/core/unshare_test.c) and programs that test file descriptor limits can trigger this issue.

We should use RB_CLEAR_NODE() set the erased node to EMPTY, then pde_subdir_next() will return NULL to avoid uaf access. We found an uaf issue while using stress-ng testing, need to run testcase getdent and tun in the same time. The steps of the issue is as follows: 1) use getdent to traverse dir /proc/pid/net/dev_snmp6/, and current pde is tun3; 2) in the [time windows] unregister netdevice tun3 and tun2, and erase them from rbtree. erase tun3 first, and then erase tun2. the pde(tun2) will be released to slab; 3) continue to getdent process, then pde_subdir_next() will return pde(tun2) which is released, it will case uaf access.

[PATCH OLK-5.10] KVM: arm64: Prevent access to vCPU events before init
by Pu Lehui 08 Dec '25

08 Dec '25

From: Oliver Upton <oliver.upton(a)linux.dev> mainline inclusion from mainline-v6.18-rc2 commit 0aa1b76fe1429629215a7c79820e4b96233ac4a3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID4A6U CVE: CVE-2025-40102 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Another day, another syzkaller bug. KVM erroneously allows userspace to pend vCPU events for a vCPU that hasn't been initialized yet, leading to KVM interpreting a bunch of uninitialized garbage for routing / injecting the exception. In one case the injection code and the hyp disagree on whether the vCPU has a 32bit EL1 and put the vCPU into an illegal mode for AArch64, tripping the BUG() in exception_target_el() during the next injection: kernel BUG at arch/arm64/kvm/inject_fault.c:40!

[PATCH OLK-5.10] vxlan: Fix NPD when refreshing an FDB entry with a nexthop object
by Pu Lehui 08 Dec '25

08 Dec '25

From: Ido Schimmel <idosch(a)nvidia.com> mainline inclusion from mainline-v6.17-rc5 commit 6ead38147ebb813f08be6ea8ef547a0e4c09559a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICYXVU CVE: CVE-2025-39851 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- VXLAN FDB entries can point to either a remote destination or an FDB nexthop group. The latter is usually used in EVPN deployments where learning is disabled. However, when learning is enabled, an incoming packet might try to refresh an FDB entry that points to an FDB nexthop group and therefore does not have a remote. Such packets should be dropped, but they are only dropped after dereferencing the non-existent remote, resulting in a NPD [1] which can be reproduced using [2]. Fix by dropping such packets earlier. Remove the misleading comment from first_remote_rcu().
