kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...

CVE-2026-80584

A flaw was found in the Linux kernel's s390/qeth component. This vulnerability allows a local attacker to trigger an integer underflow when handling user-supplied buffer lengths in the qethsnmpcommand and qethl3arpquery functions. This can lead to an out-of-bounds write, potentially causing memor...

CVE-2026-81575 Missing Sanity Checks for Buffer Lengths

If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 accepts requests with opcode 0x5e, which contain the data length and the data itself. Missing bounds checking on the data length value can lead to out of bounds reads, causing a segmentation fault that ultimately crashes...

CVE-2026-81575

CodeMeter Runtime (WIBU) prior to versions 8.41a and 9.10 is vulnerable when configured as a server. Requests carrying opcode 0x5e include a data-length field that lacks bounds checking, allowing an attacker to trigger out-of-bounds reads that result in a segmentation fault and crash the Runtime....

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the BPF code, ensure that skb-len != 0 when redirecting a packet to a tunneling device. The syzkaller function managed to trigger another case where skb-len == 0 when entering devqueuexmit. WARNING: CPU: 0, PID: 2470; Location...

CVE-2026-74712

CVE-2026-74712 is a slab-out-of-bounds read in the Linux kernel's vdpa/mlx5 driver. The create_direct_keys() function incorrectly calculates the input buffer size by including the entire structure (out + in + mtt[]) while the pointer passed to cmd_exec targets only the in field. This causes mlx5_...
