Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from registers not being initialized in the nftdochain function...

kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM

A flaw was found in the Linux kernel in net/netfilter/nftablescore.c:nftdochain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker...

RHEL 9 : kernel-rt (RHSA-2023:4138)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:4138 advisory. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirement...
