Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: core: Reject skbcopyexpand for fraglist GSO skbs. SKBGSOFRAGLIST values must not be linearized; otherwise, they become invalid. Return NULL if such an skb is passed to skbcopy or skbcopyexpand, in order to prevent a crash...

kernel: net: core: reject skb_copy(_expand) for fraglist GSO skbs

A flaw was found in the Linux kernel. When copying or expanding fragmented Generic Segmentation Offload GSO network packet buffers, the kernel improperly linearizes them, leaving the buffers in an invalid state. A local user can exploit this vulnerability to trigger a kernel crash during subseque...
