ICSA-25-226-07 — Siemens Third-Party Components in SINEC OS

nfsd: NULL dereference in nfs3svc_encode_getaclres. scsi: core: use-after-free vulnerability. NFSD: vulnerability caused by loff_t overflow on the server when a client reads near the maximum offset, causing the server to return an EINVAL error, which the client retries indefinitely, instead of handling out-of-range READ requests by returning a short result with an EOF flag. NFSD: Vulnerability caused by an underflow in ia_size due to a mismatch between signed and unsigned 64-bit file size values, which can cause issues when handling large file sizes from NFS clients. NFSD: Vulnerability handling large file sizes for NFSv3 improperly capping client size values larger than s64_max, leading to unexpected behavior and potential data corruption. sh: cpuinfo: warning for CONFIG_CPUMASK_OFFSTACK. When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected, cpu_max_bits_warn() generates a runtime warning when showing /proc/cpuinfo. A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables.

The default behavior when the stack-protector detects an overflow is to terminate your application, resulting…

OESA-2025-1065 — kernel security update

Affected: openEuler:22.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved: mm/swapfile: skip HugeTLB pages for unuse_vma I got a bad pud error and lost a 1GB HugeTLB when calling swapoff. The problem can be reproduced by the following steps: 1. Allocate an anonymous 1GB HugeTLB and some other anonymous memory. 2. Swapout the above anonymous memory. 3. run swapoff and we will get a bad pud error in kernel message: mm/pgtable-generic.c:42: bad pud 00000000743d215d(84000001400000e7) We can tell that pud_clear_bad is called by pud_none_or_clear_bad in unuse_pud_range() by ftrace. And therefore the HugeTLB pages will never be freed because we lost it from page table. We can skip HugeTLB pages for unuse_vma to fix it.(CVE-2024-50199) In the Linux kernel, the following vulnerability has been resolved: ubifs: authentication: Fix use-after-free in ubifs_tnc_end_commit After an insertion in TNC, the tree might split and cause a node to change its `znode->parent`. A further deletion of other nodes in the tree (which also could free the nodes), the aforementioned node's `znode->cparent` could still point to a freed node. This `znode->cparent` may not be updated when getting nodes to commit in `ubifs_tnc_start_commit()`. This could then trigger a use-after-free when accessing the `znode->cparent` in `write_index()` in `ubifs_tnc_end_commit()`. This can be triggered by running rm -f…
