EUVD-2026-108746

In the Linux kernel, the following vulnerability has been resolved: fs: Free any excess xarray nodes in clearinode For many years we've had a hard to hit leak of xarray nodes. Hugh documented it well in commit 786b31121a2c. Recently people and syzbot have found ways to force it to happen with...

CVE-2026-99080 fs: Free any excess xarray nodes in clear_inode()

In the Linux kernel, the following vulnerability has been resolved: fs: Free any excess xarray nodes in clearinode For many years we've had a hard to hit leak of xarray nodes. Hugh documented it well in commit 786b31121a2c. Recently people and syzbot have found ways to force it to happen with...

CVE-2026-99080

The Linux kernel contains a long-standing, difficult-to-trigger memory leak involving xarray nodes within the fs subsystem. Recent findings by syzbot and other researchers demonstrated that this leak can be forced using the madvise system call. The vulnerability was addressed by calling xa_destro...

CVE-2026-99079 net/mlx5e: Prevent stale XSK buffer release on refill retry

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent stale XSK buffer release on refill retry When an XDP redirect to an AFXDP socket fails because its RX ring is full, the XSK core frees the buffer. During the subsequent batched refill of a legacy cyclic RQ, mlx...

CVE-2026-99079

The Linux kernel (specifically the net/mlx5e driver) is affected by a vulnerability where a stale XSK buffer is released during a refill retry. When an XDP redirect to an AF_XDP socket fails due to a full RX ring, the XSK core frees the buffer. During a batched refill of a legacy cyclic RQ, the d...

CVE-2026-99078 net/mlx5e: Prevent stale XSK buffer release on MPWQE refill retry

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent stale XSK buffer release on MPWQE refill retry With AFXDP on a striding RQ, mlx5e defers releasing XSK buffers until an MPWQE is refilled. If XSK allocation then returns -ENOMEM, actualwqhead is not advanced an...

CVE-2026-99078

The Linux kernel contains a vulnerability in the net/mlx5e driver where AF_XDP on a striding RQ can result in stale XSK buffer releases during an MPWQE refill retry . If an XSK allocation returns -ENOMEM, the actual_wq_head is not advanced, causing a subsequent NAPI poll to retry the same WQE. Th...

CVE-2026-99077 ipv4: udp: Create exceptions before socket matching

In the Linux kernel, the following vulnerability has been resolved: ipv4: udp: Create exceptions before socket matching Currently, when ICMP Fragmentation Needed and Redirect Message packets are locally delivered and quote a UDP packet, a FIB nexthop exception FNHE is only created if the kernel c...

CVE-2026-99077

The Linux kernel contains a vulnerability where FIB nexthop exceptions (FNHE) are only created if a quoted UDP packet matches an existing socket. This allows off-path attackers to conduct a side-channel attack on the FNHE cache to discover ephemeral ports of connected UDP sockets. Previous mitiga...
