In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix NULL deref and buffer over-read in SDP debugfs Why & How dpsdpmessagedebugfswrite dereferences connector-base.state-crtc without checking for NULL. A connector can be connected but not bound to any CRTC e.g...

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-&...

EUVD-2026-39204

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: reject short frames before parsing A BNEP peer can send a short BNEP SDU. bneprxframe reads the packet type byte immediately and, for control packets, reads the control opcode and setup UUID-size byte before...

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...

EUVD-2026-39235

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix NULL dereference in getqueueids When usrqueueidarray is NULL and numqueues is non-zero, getqueueids returns NULL. The callers check only ISERR on the return value; since ISERRNULL == false the check passes, and...

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...

EUVD-2026-38900

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...
