CVE-2026-99081

The Linux kernel 's bnxt_en driver contains a vulnerability where small packets (under 52 bytes) are padded but the DMA mapping length remains unadjusted. This mismatch causes the NIC DMA engine to read beyond the mapped region, potentially triggering IOMMU DMA Read faults on BCM57412 NetXtreme-E...

EUVD-2026-108747

In the Linux kernel, the following vulnerability has been resolved: bnxten: fix DMA mapping length for padded small packets Stefan Fleischmann reported Intel IOMMU DMA Read faults on BCM57412 NetXtreme-E NICs when transmitting packets on VLAN/macvlan interfaces: DMAR: DMA Read NOPASID Request...

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

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...

EUVD-2026-108745

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 contains a vulnerability in the net/mlx5e driver regarding XSK buffer management . When an XDP redirect to an AF_XDP socket fails due to a full RX ring, the XSK core frees the buffer. During a subsequent batched refill of a legacy cyclic RQ, the mlx5e driver may release a WQE's X...

CVE-2026-99078

The Linux kernel contains a vulnerability in the mlx5e driver when using AF_XDP on a striding RQ. The issue occurs because the driver defers releasing XSK buffers until an MPWQE is refilled. If an allocation fails with -ENOMEM , the actual_wq_head is not advanced, causing a subsequent NAPI poll t...

EUVD-2026-108744

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...

EUVD-2026-108743

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 ICMP Fragmentation Needed and Redirect Message packets only create a FIB nexthop exception (FNHE) if the kernel can match the quoted UDP packet to an existing socket. This behavior enables off-path attackers to perform a side-channel attack on the F...

CVE-2026-99076

The Linux kernel is vulnerable to a side-channel attack in the IPv6 implementation. When ICMPv6 Packet Too Big and Redirect Message packets are locally delivered and quote a UDP packet, the kernel previously only created an exception in the IPv6 exception cache if the UDP packet matched an existi...

EUVD-2026-108742

In the Linux kernel, the following vulnerability has been resolved: ipv6: udp: Create exceptions before socket matching Currently, when ICMPv6 Packet Too Big and Redirect Message packets are locally delivered and quote a UDP packet, an exception is only created in the IPv6 exception cache if the...

EUVD-2026-108741

In the Linux kernel, the following vulnerability has been resolved: rustbinder: reschedule node refcount update on thread exit When a thread exits via BINDERTHREADEXIT, its pending work items are cancelled. If a thread exits while holding a pending node refcount increment e.g. pushed as deferred...

CVE-2026-99075

The Linux kernel contains a vulnerability in the rust_binder component regarding a reschedule node refcount update during thread exit. When a thread exits via BINDER_THREAD_EXIT, pending work items are cancelled. If a thread exits while holding a pending node refcount increment as deferred work, ...

EUVD-2026-108740

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop PMTU walk when nexthop group shrinks Commit 7d3f3b4367f3 "net: ipv4: Cache pmtu for all packet paths if multipath enabled" made iprtupdatepmtu update every path. For nexthop objects, fibinfonumpath and fibinfonhc...

CVE-2026-99074

The Linux kernel contains a vulnerability where a null-pointer dereference can occur during the PMTU (Path MTU) walk process. The root cause is a race condition: while RCU protects the lifetime of nexthop groups, it does not ensure that fib_info_num_path() and fib_info_nhc() observe the same grou...

CVE-2026-99073

The Linux kernel contains a vulnerability where an IPv4 Forwarding Information Base (FIB) dump could lead to a null pointer dereference. The issue occurs because fib_dump_info_fnhe() uses a loop bound that may become invalid if an RTM_NEWNEXTHOP operation replaces a nexthop group with fewer paths...

EUVD-2026-108739

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop exception dump when nexthop group shrinks Commit 4ce5dc9316de "inet: switch inetdumpfib to RCU protection" allowed IPv4 FIB dumps to run concurrently with nexthop replacement. fibdumpinfofnhe uses fibinfonumpath as the...

EUVD-2026-108738

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop route notification sizing when nexthop group shrinks Commit 680aea08e78c "net: ipv4: Emit notification when fib hardware flags are changed" added an RCU-only fibnlmsgsize call for asynchronous hardware flag...
