CVE-2026-80984

A flaw was found in the net/smc component of the Linux kernel. When a link group terminates while a socket is waiting in smcclosestreamwait, a NULL pointer dereference can occur during the SMC-D teardown path. This can lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-89696

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd. A remote client can exploit this by sending a specially crafted NFS COMPOUND request. This request, when processed, can lead to a NULL pointer dereference in the nfsd kthread, causing the system to crash and resulting in ...

CVE-2026-80956

A flaw was found in the Linux kernel's dm-pcache component. A crafted image can cause the getcachesegment function to return an uninitialized cache segment. This uninitialized segment, containing a null data pointer, is then used by cacheksetclose without a proper null check. This can lead to a...

CVE-2026-80963

A flaw was found in the Linux kernel's dm-stats module. This vulnerability occurs when the allocation of per-CPU data fails, which can lead to a null pointer dereference during the subsequent cleanup operation. This issue can cause the system to crash, resulting in a Denial of Service DoS...

CVE-2026-89460

A flaw was found in the Linux kernel. A local user can trigger a kernel panic by running the perf stat command while CPUs are being hotplugged. This occurs because the system fails to properly allocate CPU event structures for newly online CPUs, leading to a null pointer dereference. Successful...

CVE-2026-89442

A flaw was found in the Linux kernel. The isstifclosassoc ioctl function in the platform/x86: ISST module contains an improper validation of the socketid. This allows a local attacker to cause an out-of-bounds access or a NULL pointer dereference. This could lead to a system crash, resulting in a...

d-os-descriptor 概述 USB小工具子系统在compositesetup函数（composite.c）的OS描述符处理部分存在安全问题。处理精心构造的控制传输请求消息会因空指针解引用或内存损坏而导致设备崩溃。 描述 compositesetup中针对接口接收者的OS描述符处理部分实现如下。 root@kitploit: case USBRECIPINTERFACE: if windex != 0x5 || wvalue 8 break; interface = wvalue & 0xFF; buf6 = windex; count =...

CVE-2026-80993

A flaw was found in the Linux kernel's net: phylink component. The phylinkinbandcaps function does not correctly validate the return value from macselectpcs, which can return an error pointer instead of a valid Physical Coding Sublayer PCS object. This oversight can lead to dereferencing an inval...

CVE-2026-89717

A flaw was found in the zram component of the Linux kernel. When zramdestroycomps is called, it incorrectly resets the primary compressor to a NULL state. This invalid state can lead to a NULL pointer dereference when compalgorithmshow attempts to access the compressor, potentially causing system...

CVE-2026-89552

A flaw was found in the Linux kernel. When updating charp parameters, an allocation failure can cause the parameter to be set to NULL before the new value is successfully allocated. This can lead to a kernel NULL pointer dereference, which may result in a system crash and a denial of service...

CVE-2026-89439

A flaw was found in the Linux kernel's Intel Speed Select Technology ISST driver. A missing NULL check for isstcommon.sstinst during failed socket loading could allow a local attacker to trigger a NULL pointer dereference. This vulnerability could lead to a system crash, resulting in a Denial of...

CVE-2026-89591

A flaw was found in the Linux kernel's accel/rocket module. During error handling in the rocketioctlsubmitjob function, a cleanup routine may attempt to free a job-domain pointer that has not yet been initialized, leading to a NULL pointer dereference. A local attacker could exploit this...

CVE-2026-89517

A flaw was found in the Linux kernel's schedext component, which handles core scheduling. When multiple selections on the same core interleave due to a dropped lock, they can corrupt the scheduling state. This corruption can lead to a NULL dereference, tasks remaining active after being dequeued,...

CVE-2026-89477

A flaw was found in the Stream Control Transmission Protocol SCTP implementation within the Linux kernel. This vulnerability occurs when the kernel attempts to complete a stream reconfiguration request that has not been fully transmitted, leading to a null pointer dereference. An unprivileged loc...

CVE-2026-89509

A flaw was found in the Linux kernel's RDMA/ionic driver. This vulnerability arises from the driver's incorrect handling of rdmacounter allocations, specifically by not embedding counter driver data as required. This oversight can lead to a NULL pointer dereference when the allocandbind function ...

CVE-2026-89709

A flaw was found in the Linux kernel's lockd and nfsd components. An unguarded dereference of nlmsvcops after the nfsd module is removed can lead to a NULL pointer dereference or a use-after-free condition. This vulnerability could allow a local attacker to cause a denial of service...

CVE-2026-89528

A flaw was found in the Linux kernel's svcrdma component. A remote attacker could send specially crafted Read lists that exceed the page budget. This can lead to a NULL pointer dereference during Direct Memory Access DMA mapping, potentially causing a system crash and a denial of service...

CVE-2026-89506

A flaw was found in the Linux kernel's RDMA/uverbs component. A missing update to the UVERBSMETHODREGMR ioctl allows a malicious userspace program to trigger a null pointer dereference in specific RDMA drivers mthca, irdma, siw. This can lead to a system crash, resulting in a Denial of Service Do...

CVE-2026-89592

A flaw was found in the accel/rocket component of the Linux kernel. This vulnerability arises from two issues: a missing null check after a memory allocation failure and an integer overflow when calculating memory requirements based on user-supplied values. An attacker could exploit these flaws t...

CVE-2026-89484

A flaw was found in the Linux kernel's lockd component. This vulnerability occurs when the Network Lock Manager NLM client attempts to initialize file lock operations without successfully allocating a lockowner. This can lead to a NULL pointer dereference during the release of the file lock,...
