The vulnerability of the rxrpc_post_response() function in the net/rxrpc/conn_event.c module exposes session sockets supported by the RxRPC support in the Linux operating system, allowing a attacker to cause a service failure.

The vulnerability of the rxrpcpostresponse function in the net/rxrpc/connevent.c module, which is part of the RxRPC session support in Linux kernel, is related to incorrect comparisons when using erroneous factors. Exploiting this vulnerability can allow an attacker to cause service failures...

The vulnerability of the rxgk_verify_authenticator() function in the net/rxrpc/rxgk.c module allows attackers to access protected information or cause service failures under Linux operating system kernels.

The vulnerability of the rxgkverifyauthenticator function in the net/rxrpc/rxgk.c module relates to the execution of operations outside the buffer in the memory of the Linux operating system’s kernel. Exploiting this vulnerability could allow a remote attacker to gain access to protected...

The vulnerability of the rxrpc_preparse_xdr_yfs_rxgk() function in the net/rxrpc/key.c module, which is part of the RxRPC session support in the Linux operating system’s kernel, allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the rxrpcpreparsexdryfsrxgk function in the net/rxrpc/key.c module, which is part of the RxRPC session support in the Linux operating system’s kernel, involves integer overflow. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity...

kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...
