Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: nvme: Fixed a multipath crash caused by the flush request when blktrace is enabled. The flush request initialized by blkkickflush has a NULL bio. This issue may be addressed during the nvmeendreq operation during io completion...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: blktrace: Fixed a UAF in the blkTraceAccess function after removal by sysfs. There is a use-after-free issue triggered by the following process: bash P1sda P2sdb echo 0 /sys/block/sdb/trace/enable blkTraceRemoveQueue...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: trace/blktrace: A memory leak was fixed by using debugfslookup. When calling debugfslookup, the result must also call dput, otherwise a memory leak will occur over time. To simplify things, simply call debugfslookupandremove, whi...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: block: fixed leakage of debugfs entries caused by blktrace. The commit 99d055b4fd4b “block: removed per-disk debugfs files in blkunregisterqueue” moves the blkTraceShutdown function to blkUnregisterQueue. This is safe if blktrace...

CVE-2026-23374

A flaw was found in the Linux kernel's blktrace component. This vulnerability arises when the tracingrecordcmdline function attempts to access a per-CPU variable in a preemptible context, which is an unsafe operation. A local attacker could exploit this to trigger a kernel bug, potentially leadin...

CVE-2026-23374

CVE-2026-23374 affects the Linux kernel blktrace path. The root cause is tracing_record_cmdline() using __this_cpu_read()/__this_cpu_write() on a per-CPU variable while preemption is enabled, which is unsafe and triggers a kernel BUG in preemptible code through __blk_add_trace() paths. Public wri...
