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...

DEBIAN-CVE-2026-89769

In the Linux kernel, the following vulnerability has been resolved: clocksource/drivers/nxp-pit: Fix IRQ leak on cpuhpsetupstate error path When cpuhpsetupstate fails after pitclockeventpercpuinit has successfully called requestirq, the error handling jumps directly to outpitclocksourceunregister...
