kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

kernel: net: do not leave a dangling sk pointer, when socket creation fails

A vulnerability was found in the Linux kernel's networking component in the sockrelease function, where a dangling pointer can occur when socket creation fails. This happens when a reference to the socket is not cleared, leading to a use-after-free condition...

kernel: net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket

A flaw was found in the Linux kernel's bpf programs. Under certain conditions, when the kernel attempts to initiate a network connection using the kernelconnect function, it can return a value that causes the cxtcpsetupsocket function to loop. This issue can lead to continuous data writing to the...

kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service

An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size MSS of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increas...
