Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the blkaddTrace function using the thiscpu operation within preemptible contexts, potentially leading t...

Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-004406)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004406 advisory. In the Linux kernel 5.4.0-rc2, there is a use-after-free read in the blkaddtrace function in kernel/trace/blktrace.c which is used to fill out a blkiotrace structure...

SUSE CVE-2019-19768

In the Linux kernel 5.4.0-rc2, there is a use-after-free read in the blkaddtrace function in kernel/trace/blktrace.c which is used to fill out a blkiotrace structure and place it in a per-cpu sub-buffer...

kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c

A use-after-free vulnerability was found in the Linux kernel’s implementation of blktrace in the blkaddtrace function. A local attacker with permissions to run block trace instructions against a device can create a situation where the core blocktrace object is used after it is freed. The attacker...
