CVE-2022-49805

CVE-2022-49805 – Linux kernel (lan966x): The issue occurs in lan966x_stats_init(), which calls create_singlethread_workqueue() without validating the return value. If it returns NULL, a later queue_delayed_work path dereferences a null workqueue pointer, causing a null-pointer dereference. The re...

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix memory leak in testgensynthcmd and testemptysynthevent testgensynthcmd only free buf in fail path, hence buf will leak when there is no failure. Add kfreebuf to prevent the memleak. The same reason and solution in...

CVE-2022-49801

CVE-2022-49801 is a Linux kernel vulnerability tied to the tracing subsystem, specifically a memory leak in tracing_read_pipe() that can trigger a kmemleak-unreferenced-object issue. The linked OpenVAS/Nessus entries and EulerOS advisories (EulerOS-SA-2025-2546, EulerOS-SA-2025-2296, etc.) list t...

CVE-2022-49799 tracing: Fix wild-memory-access in register_synth_event()

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix wild-memory-access in registersynthevent In registersynthevent, if setsyntheventprintfmt failed, then both traceremoveeventcall and unregistertraceevent will be called, which means the traceeventcall will call...

CVE-2022-49798 tracing: Fix race where eprobes can be called before the event

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix race where eprobes can be called before the event The flag that tells the event to call its triggers after reading the event is set for eprobes after the eprobe is enabled. This leads to a race where the eprobe may b...

CVE-2022-49797

CVE-2022-49797 concerns the Linux kernel tracing subsystem. The vulnerability is a potential NULL pointer dereference in the kprobe path: when trace_get_event_file() fails, gen_kretprobe_test may be marked as the error code, and if the kprobe_event_gen_test module is removed, a dereference can oc...

CVE-2022-49794

CVE-2022-49794 affects the Linux kernel IIO ADC driver (iio: adc: at91_adc). The issue is a potential memory leak in at91_adc_allocate_trigger where, if iio_trigger_register() returns an error, the driver should free the trigger reference via iio_trigger_free() and then release memory with iio_tr...
