Description
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to use of uninitialized resource within the sizeof() function in net/core/filter.c, within the sizeof() function in kernel/trace/bpf_trace.c, within the arg_type_is_dynptr() function in kernel/bpf/verifier.c, within the sizeof() function in kernel/bpf/syscall.c, within the sizeof() function in kernel/bpf/helpers.c. A local user can perform a denial of service (DoS) attack.
Remediation
Install update from vendor's website.
