Astra Linux - уязвимость в linux-5.10, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: trace/blktrace: fix memory leak with using debugfslookup When calling debugfslookup the result must have dput called on it, otherwise the memory will leak over time. To make things simpler, just call debugfslookupandremove instea...

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...
