TITLE

Linux  of  Linux Kernel  In  NULL  Pointer dereference vulnerability

DESCRIPTION

In the Linux kernel, the following vulnerability has been resolved: tls: fix missing memory barrier in tls_init In tls_init(), a write memory barrier is missing, and store-store reordering may cause NULL dereference in tls_{setsockopt,getsockopt}. CPU0 CPU1 ----- ----- // In tls_init() // In tls_ctx_create() ctx = kzalloc() ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1) // In update_sk_prot() WRITE_ONCE(sk->sk_prot, tls_prots) -(2) // In sock_common_setsockopt() READ_ONCE(sk->sk_prot)->setsockopt() // In tls_{setsockopt,getsockopt}() ctx->sk_proto->setsockopt() -(3) In the above scenario, when (1) and (2) are reordered, (3) can observe the NULL value of ctx->sk_proto, causing NULL dereference. To fix it, we rely on rcu_assign_pointer() which implies the release barrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is initialized, we can ensure that ctx->sk_proto are visible when changing sk->sk_prot. Linux of Linux Kernel for, NULL There is a vulnerability in pointer dereference.Service operation interruption (DoS) It may be in a state. 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. ========================================================================== Ubuntu Security Notice USN-7009-1 September 13, 2024 linux-azure, linux-azure-5.15, linux-azure-fde vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-azure-fde: Linux kernel for Microsoft Azure CVM cloud systems - linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems Details: Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-23848) Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel did not properly check for the device to be enabled before writing. A local attacker could possibly use this to cause a denial of service. (CVE-2024-25741) It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-40902) Several security issues were discovered in the Linux kernel.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
