In the Linux kernel, the following vulnerability has been resolved: xdp: Remove WARN() from __xdp_reg_mem_model() syzkaller reports a warning in __xdp_reg_mem_model(). The warning occurs only if __mem_id_init_hash_table() returns an error. It returns the error in two cases: 1. memory allocation fails; 2. rhashtable_init() fails when some fields of rhashtable_params struct are not initialized properly. The second case cannot happen since there is a static const rhashtable_params struct with valid fields. So, warning is only triggered when there is a problem with memory allocation. Thus, there is no sense in using WARN() to handle this error and it can be safely removed.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers register store validation for NFT_DATA_VALUE is conditional, however, the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This only requires a new helper function to infer the register type from the set datatype so this conditional check can be removed. Otherwise, pointer to chain object can be leaked through the registers. Linux of Linux Kernel Contains a vulnerability regarding the lack of free memory after expiration.Service operation interruption (DoS) It may be in a state. This vulnerability allows local attackers to disclose sensitive information on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the implementation of packet filtering. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. The RUGGEDCOM RST2428P is a Layer 2 Ethernet switch based on the SINEC operating system with up to 28 non-blocking interfaces. SCALANCE X switches are used to connect industrial components such as programmable logic controllers (PLCs) or human-machine interfaces (HMIs). Multiple vulnerabilities in third-party components of Siemens' SINEC OS could allow attackers to gain control of the server
