CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to memory corruption within the sctp_v4_del_protocol(), sctp_net_init(), sctp_net_exit(), sctp_init() and sctp_exit() functions in net/sctp/protocol.c. A local user can perform a denial of service (DoS) attack.

The vulnerability allows a local attacker to cause DoS condition on the target system.

The weakness exists in the key_gc_unused_keys function in security/keys/gc.c due to improper input validation. A local attacker can submit specially crafted keyctl commands and cause the service to crash.
