Package: lttng-modules-dkms Version: 2.14.1-1 Severity: important Since kernel v6.13, the in-kernel syscall tracepoints call the probes from faultable context (with preemption enabled). This only affects preemptible kernel configurations (PREEMPT, PREEMPT_LAZY) which includes the default debian amd64 kernel.
Using the lttng syscall tracing with kernels >= 6.13 can thus result in memory corruption and kernel lockup. -- System Information: Debian Release: forky/sid APT prefers testing APT policy: (500, 'testing'), (10, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.16.9+deb14-amd64 (SMP w/2 CPU threads; PREEMPT) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages lttng-modules-dkms depends on: ii dkms 3.2.2-1 Versions of packages lttng-modules-dkms recommends: pn lttng-tools <none> lttng-modules-dkms suggests no packages. -- no debconf information
