CVE-2026-53271

The CVE-2026-53271 issue affects the Linux kernel ksmbd during oplock/lease break notifications (smb2_oplock_break_noti and smb2_lease_break_noti). The root cause is reading opinfo->conn into a local variable without READ_ONCE() and without a NULL check after opinfo_get_list() has dropped ci-&...

CVE-2026-53220

In the Linux kernel, CVE-2026-53220 affects netfilter bridge handling. The function ebt_redirect_tg() dereferences br_port_get_rcu() without a NULL check, leading to a kernel panic if the bridge port was removed between the original hook and an NFQUEUE reinject. The work-around uses the _upper AP...

CVE-2026-53214

The CVE-2026-53214 entry documents a Linux kernel IPv6 issue where addrconf_get_prefix_route() may return the fib6_null_entry sentinel, which has a NULL fib6_table pointer. If code subsequently sets a route’s expiration time without validating the entry, a null pointer dereference (NPD) can occur...

CVE-2026-53177

In the Linux kernel, the bnxt_en driver fixes a NULL pointer dereference in PCIe error handling. The vulnerability arises when PCIe errors detected by a Root Port or Downstream Port trigger error recovery on subordinate devices even if the NIC is administratively down. Specifically, the .error_de...

CVE-2026-53163

The CVE concerns the Linux kernel rtmutex path: specifically, a vulnerability in remove_waiter() that could dereference a waiter not enqueued, triggered via FUTEX_CMP_REQUEUE_PI. The issue is tied to task_blocks_on_rt_mutex() not arming the waiter on deadlock detection, leaving waiter->task NU...

CVE-2026-53135

CVE-2026-53135: Linux kernel drm/amd/display SDP debugfs vulnerability fixed. The function dp_sdp_message_debugfs_write() dereferenced connector->base.state->crtc without NULL checks, which could occur when a connector is connected but not bound to a CRTC (e.g., after hot-plug). This caused...

CVE-2026-13201

A flaw was found in KubeVirt's safepath package. The OpenAtNoFollow function uses OPATH|ONOFOLLOW to obtain a file descriptor to a path leaf, but downstream helpers operate via /proc/self/fd/N using link-following syscalls. When the leaf is a symlink, the kernel dereferences it, defeating the...

CVE-2026-52923

A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL deref in mapkptrmatchtype for scalar regs Commit ab6c637ad027 "bpf: Fix a bpfkptrxchg issue with local kptr" refactored mapkptrmatchtype to branch on btfiskernel before checking basetype. A scalar register stored in...

EUVD-2026-38875

In the Linux kernel, the following vulnerability has been resolved: ice: fix potential NULL pointer deref in error path of icesetringparam icesetringparam nullifies tstampring of temporary txrings, without clearing ICETXRINGFLAGSTXTIME bit. When ICETXRINGFLAGSTXTIME is set and the subsequent...

EUVD-2026-38932

In the Linux kernel, the following vulnerability has been resolved: dm cache: fix null-deref with concurrent writes in passthrough mode In passthrough mode, when dm-cache starts to invalidate a cache entry and bio prison cell lock fails due to concurrent write to the same cached block, mg-cell...

CVE-2026-52941

A flaw was found in the Linux kernel's net/smc module. An unprivileged local user could trigger a null pointer dereference by performing sendmsg or recvmsg operations on an SMC-D Shared Memory Communications - Direct socket while the smcmsgevent tracepoint is enabled. This can lead to a general...

CVE-2026-52938

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF storage. A race condition can occur where a storage element is accessed after its associated map has been deallocated, leading to a null pointer dereference. This can cause a kernel crash, resulting in a Denial of Service DoS for t...

CVE-2026-52939

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS component. An unprivileged local user can trigger a kernel panic by sending a specially crafted atomic control message cmsg over an active RDS/InfiniBand IB connection. This issue is caused by improper handling of masked atomic...

EUVD-2026-38711

In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid NULL deref of conn-lnk in smcmsgevent tracepoint The smcmsgevent tracepoint class, shared by smctxsendmsg and smcrxrecvmsg, unconditionally dereferences smc-conn.lnk: stringname, smc-conn.lnk-ibname conn-lnk is onl...

CVE-2026-52939

Linux kernel vulnerability CVE-2026-52939 affects RDS over InfiniBand. A NULL dereference can occur in rds_ib_send_cqe_handler() when handling masked atomic completions, due to rds_ib_send_unmap_op() not covering masked opcodes. The issue occurs because masked atomic opcodes (IB_WR_MASKED_ATOMIC_...
