The vulnerability of the svc_rdma_copyInline_range() function in the net/sunrpc/xprtrdma/svc_rdma_rw.c module of the Linux operating system’s RPC protocol implementation allows a attacker to gain access to protected information or cause service failures.

The vulnerability of the svcrdmacopyInlinerange function in the net/sunrpc/xprtrdma/svcrdmarw.c module of the Linux operating system’s RPC protocol is related to an improper check of the specified index, position, or offset in the input data. Exploiting this vulnerability could allow an attacker ...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: authgss: Fixed memory leaks in XDR decoding error paths. The functions gssxdecctx, gssxdecstatus, and gssxdecname allocate memory through gssxdecbuffer, which calls kmemdup. When a subsequent decoding operation fails, the...
