In the Linux kernel, the following vulnerability has been resolved:

tracing: Fix null pointer dereference in tracing_err_log_open()

Fix an issue in function 'tracing_err_log_open'. The function doesn't call 'seq_open' if the file is opened only with write permissions, which results in 'file->private_data' being left as null. If we then use 'lseek' on that opened file, 'seq_lseek' dereferences 'file->private_data' in 'mutex_lock(&m->lock)', resulting in a kernel panic. Writing to this node requires root privileges, therefore this bug has very little security impact.

Tracefs node: /sys/kernel/tracing/error_log

Example Kernel panic:
