CVE-2026-89627

A flaw was found in the Linux kernel's HID Human Interface Device roccat driver. When a roccat device is destroyed, the driver fails to properly free buffered reports, leading to a memory leak. A local attacker could potentially exploit this to exhaust system memory, resulting in a Denial of...

CVE-2026-89711

A flaw was found in the Linux kernel's Network File System Daemon NFSD. An invalid assumption in the nfsdmodecheck function regarding directory lookup capabilities during NFS reexport could lead to a null pointer dereference. A remote attacker could exploit this by performing a LOOKUP operation o...

CVE-2026-89594

A flaw was found in the Linux kernel's OMAP SSI driver. The driver uses a synthetic HSI controller device that does not properly initialize its Direct Memory Access DMA mask. This oversight can lead to the driver crashing or triggering warnings when attempting DMA mapping operations, potentially...

CVE-2026-89570

A flaw was found in the Linux kernel's Compute Express Link CXL subsystem. Lifetime issues with the CXL Machine Check Exception MCE notifier can lead to NULL dereferences and use-after-free vulnerabilities in the MCE handler. This could allow an attacker to cause system instability or a denial of...

CVE-2026-89554

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. When reconstructing a Multipath TCP MPTCP join request under SYN cookies, the localid field is not properly initialized. An off-path attacker can influence this uninitialized field by sending concurrent MPJOIN SYN requests...

CVE-2026-89525

A flaw was found in the Linux kernel. A local attacker could craft a malicious Universal Disk Format UDF image to trigger an out-of-bounds read vulnerability in the udfgetpblockvirt15 function. This occurs when the system attempts to read a Virtual Allocation Table VAT index equal to the entry...

CVE-2026-89453

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit driver for AMD. This vulnerability occurs when the system handles certain memory access errors, specifically Page Request PPR faults, without properly releasing a reference to a PCI device. This oversight causes a...

CVE-2026-81014

A flaw was found in the Linux kernel's hp-bioscfg module. A local attacker with write access to the sysfs entry for hp-bioscfg could exploit a heap out-of-bounds read vulnerability. This occurs because the skstore and kekstore functions incorrectly handle input that ends with a newline character,...

CVE-2026-81011

A flaw was found in the Linux kernel's hp-bioscfg module. The module's package parsers incorrectly determine the number of elements in a package, using a value derived from a name string rather than the true package size. While currently prevented by existing validation, a future change to the...

CVE-2026-89759

A flaw was found in the Linux kernel's memory leak detector kmemleak. When kmemleakscan attempts to scan task stacks on systems with a large number of threads, it can hold a CPU for an extended period without allowing other processes to run. This can lead to a 'soft lockup,' where the system...

CVE-2026-89603

A flaw was found in the Linux kernel. A race condition exists where a seccomp filter, intended to restrict system calls, can be bypassed by an unprivileged process. This occurs when a thread is stopped for tracing ptrace and another thread attempts to apply a seccomp filter with the...

CVE-2026-89556

A flaw was found in the Linux kernel. This vulnerability arises from insufficient validation of string table section types within ELF Executable and Linkable Format files. A local attacker could exploit this by providing a specially crafted ELF module, leading to the kernel attempting to access...

CVE-2026-89499

A flaw was found in the Linux kernel's ring-buffer component. When a remote reader update fails during a page swap, the system incorrectly proceeds as if the swap succeeded. This can lead to log flooding, potentially causing a denial of service by exhausting system resources or hindering system...

CVE-2026-89452

A flaw was found in the iommu/msm component of the Linux kernel. This vulnerability occurs when msmiommuprobe fails to properly unwind its probe state during registration, leaving a dangling list entry. A local attacker could potentially exploit this to cause a dereference of the dangling list...

CVE-2026-80972

A flaw was found in the ALSA Advanced Linux Sound Architecture aloop driver within the Linux kernel. This vulnerability arises from insufficient validation of the card index during device setup, specifically when a device is manually configured using the sysfs interface. A local attacker could...

CVE-2026-89705

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. This vulnerability occurs due to a synchronization issue where a status counter rqstatuscounter is not correctly reset on all exit paths within the nfsddispatch function. This can lead to a race condition where a lockles...

CVE-2026-89667

A flaw was found in the Linux kernel's Network File System Daemon nfsd file caching mechanism. A race condition can occur during concurrent shutdown operations and file disposal, where a file might be unhashed and moved to a dispose list, but the shutdown process misses it. This can lead to a...

CVE-2026-89579

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF component, specifically impacting 32-bit systems. This vulnerability stems from incorrect sizing and indexing of bloom filters, which can lead to out-of-bounds memory access. A local attacker with CAPBPF capabilities could exploit...

CVE-2026-89532

A flaw was found in the Linux kernel's svcrdma component. A remote attacker could send a specially crafted network packet that causes an integer underflow in the pclforeachsegment function when processing a chunk with zero segments. This vulnerability leads to an out-of-bounds read, resulting in ...

CVE-2026-89492

A flaw was found in the Linux kernel's OCFS2 filesystem. A local attacker with the ability to mount a crafted on-disk image could exploit this vulnerability by providing excessive directory-index entry counts when reading metadata. This can lead to an out-of-bounds read, potentially causing...
