In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: set timer-privatedata before registering the PCM timer sndpcmtimerinit calls snddeviceregister to link the new struct sndtimer into the global timer list while it still carries hw.cresolution = sndpcmtimerresolution an...

UBUNTU-CVE-2026-98308

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: trace PCM open only after assigning a stream Stream assignment can fail when hardware streams are exhausted. Move the tracepoint after the NULL check because its payload accesses the assigned stream tag. Detected by...

CVE-2026-98268

In the Linux kernel, the following vulnerability has been resolved: perf: Fix null pointer access in isincludeguestevent A typical module unload occurring event when there is an active perf connection leads to freeing of the pmu pointer. The call log is something like: .. pmudetachevent...

CVE-2026-98355

In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs: guard against null kobj name In the client, if initpath errors, the callee tries to clean up with rtrscltcloseconns. However, this can lead to calling the event tracing code with cltpath-kobj-name being NULL and thus...
