CVE-2026-31774

The CVE-2026-31774 issue affects the Linux kernel io_uring/net path. A 32-bit length value (sqe->len) is stored into sr->len (int), allowing values above INT_MAX (e.g., 0xFFFFFFFF) to overflow and propagate through the bundle recv/send path. This can cause a slab-out-of-bounds read in io_bu...

The vulnerability of the rxrpc_recvmsg() function in the net/rxrpc/recvmsg.c module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the rxrpcrecvmsg function in the net/rxrpc/recvmsg.c module of the Linux kernel is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-31677

A flaw was found in the Linux kernel's afalg Algorithm Interface component. This vulnerability allows a local attacker to cause a denial of service DoS by sending specially crafted requests. The afalggetrsgl function fails to properly limit the extraction of receive scatterlist RX SG data based o...

The vulnerability of the tcp_bpf_recvmsg_parser in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the tcpbpfrecvmsg parser in the Linux operating system’s kernel is related to the execution of a loop with an unreachable exit condition. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-31677

The CVE-2026-31677 issue affects the Linux kernel af_alg path. The root cause is that af_alg_get_rsgl() could extract RX scatterlist data beyond the remaining receive budget, allowing a local attacker to trigger a DoS via recvmsg when there isn’t enough RX space for a chunk. The fix tightens budg...
