Red Hat Security Advisory 2023-2148-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, bypass, denial of service, double free, memory leak, null pointer, out of bounds read, privilege escalation, traversal, and use-after-free vulnerabilities.
6bb9ce98c5ca5dc774537375166af3e798834e2da1f2c0b13a4afe3ba747e53eRed Hat Security Advisory 2023-2458-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include buffer overflow, bypass, denial of service, double free, memory leak, null pointer, out of bounds read, privilege escalation, traversal, and use-after-free vulnerabilities.
b58a384a712b94d52e42ea512d4e07fd1f095c48a71c4ad8aa3f7089d090a83aUbuntu Security Notice 5541-1 - Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not perform permission checks correctly in some situations. A local attacker could possibly use this to gain administrative privileges. Jann Horn discovered that the FUSE file system in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
e964411e2a44ec6b1d66fca5a48f54b1a1e945a816cc42a923278a78bcde118eUbuntu Security Notice 5539-1 - It was discovered that the implementation of the 6pack and mkiss protocols in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service. Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not handle detach events properly in some situations. A local attacker could possibly use this to cause a denial of service or execute arbitrary code.
e0f1dc9c61a271fdd2e51e74092004e7786f7464ac5a1e07c3a459de607c3affUbuntu Security Notice 5493-2 - It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service.
c8f525108fa7be13c257cf7500504a9d9cd5bc3541289a85c422b676e908bc56Ubuntu Security Notice 5493-1 - It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service.
aba96a2ada06641504d1bb9ac2a3c0ed4c3e957107d4dca892497c06c4bf64fcUbuntu Security Notice 5469-1 - It was discovered that the Linux kernel did not properly restrict access to the kernel debugger when booted in secure boot environments. A privileged attacker could use this to bypass UEFI Secure Boot restrictions. Aaron Adams discovered that the netfilter subsystem in the Linux kernel did not properly handle the removal of stateful expressions in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code.
4ce717877a9ad9825a852ffb1c677186dfde79c8f40631b1893230bba71c8954Ubuntu Security Notice 5416-1 - Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM implementation in the Linux kernel did not properly perform guest page table updates in some situations. An attacker in a guest vm could possibly use this to crash the host OS. It was discovered that the implementation of X.25 network protocols in the Linux kernel did not terminate link layer sessions properly. A local attacker could possibly use this to cause a denial of service.
