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-2026-89733

A flaw was found in the Linux kernel's USB Video Class UVC gadget driver. This vulnerability occurs in the uvcfunctionbind and uvcfunctionunbind functions, where pointers to freed memory are not properly cleared. This can lead to a use-after-free UAF condition, potentially allowing an attacker to...

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-2026-89505

A flaw was found in the Linux kernel's RDMA/uverbs component. Malformed input from a provider in the legacy write path can cause the uverbsgethandlerfn function to dereference an uninitialized pointer. This can lead to a system crash, resulting in a denial of service...

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. Mitigation...

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,...

CVE-2026-89504

A flaw was found in the Linux kernel's regulator subsystem. This vulnerability arises from a programming error where a device tree node pointer is released too early, creating a "dangling pointer"—a reference to memory that is no longer valid. This can lead to system instability, potentially...

CVE-2026-89511

A flaw was found in the qede driver in the Linux kernel. Under specific memory pressure conditions, the driver can encounter a NULL pointer dereference when processing network traffic using TPA TCP Segmentation Offload continuation fragments. This issue stems from an uninitialized data pointer,...

CVE-2026-89489

A flaw was found in the Linux kernel. The sysor1katomic syscall, specific to the openrisc architecture, does not adequately validate user-provided pointers. An unprivileged process can exploit this by supplying kernel addresses to the syscall, gaining unauthorized read and write access to kernel...

CVE-2026-89457

A flaw was found in the s390/dasd component of the Linux kernel. An unprivileged local user can trigger a null pointer dereference by reading specific world-readable sysfs attributes while the device is being brought online. This can lead to a kernel panic, resulting in a denial of service...

CVE-2026-80992

A flaw was found in the net: ravb component of the Linux kernel. This vulnerability allows for a NULL pointer dereference when the Precision Time Protocol PTP clock's index is queried before it is properly initialized or if its registration fails. This issue could lead to a system crash, resultin...

CVE-2026-89555

A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS subsystem. When processing specially crafted Geneve packets through an MPLS multipath setup, a use-after-free vulnerability occurs. This issue arises because a cached header pointer hdr is not reloaded after pskbmaypull...

DEBIAN-CVE-2026-89770

In the Linux kernel, the following vulnerability has been resolved: iomap: don't free integrity payload that doesn't exist fsbiointegrityalloc might not allocate a bio integrity payload if PI verification is disabled on the block device. Check for that case before calling fsbiointegrityfree in...
