extract_user_to_sg in lib/scatterlist.c in the Linux kernel before 6.4.2 fails to unpin pages in a certain situation, as demonstrated by a WARNING for try_grab_page.

** DISPUTED ** An issue was discovered in the Linux kernel through 6.5.7. kvm_arch_vcpu_ioctl_run in arch/x86/kvm/x86.c allows a WARN_ON_ONCE if userspace stuffs a nonsensical vCPU state.

Red Hat Product Security is pleased to announce that official Red Hat vulnerability data is now available in a new format called the Vulnerability Exploitability eXchange (VEX). In April 2023, we mentioned in an article titled “The future of Red Hat security data”, that Red Hat was working on providing a new security data format. This new format has been created to replace the old OVAL data format, which we aim to deprecate at the end of 2024. Since February 2023, Red Hat has published Red Hat security advisories (RHSAs) in the CSAF format as an official, recommended authoritative sourc

Almost 10 years ago, researchers identified and presented the "triple handshake" man-in-the-middle attack in TLS 1.2. The vulnerability breaks confidentiality of the connection and allows an attacker to impersonate a client. In response, RFC 7627 introduced the Extended Master Secret Extension for TLS 1.2 in September 2015, which prevents the attack. All major TLS libraries now support the Extended Master Secret (EMS) and enable it by default. Unfortunately, many older operating systems and embedded devices such as WiFi access points and home routers do not support it. For example, Red Hat

An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel before 6.5.3. A buffer size may not be adequate for frames larger than the MTU.

An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker can trigger a race condition that results in a fill_kobj_path out-of-bounds write.

An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux kernel before 6.2.5. An object could potentially extend beyond the end of an allocation.

IBM QRadar SIEM 7.5.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 254138
