CVE-2026-64603

A flaw was found in the Linux kernel's intel-hid driver. A race condition can occur in the ACPI Advanced Configuration and Power Interface notify handler when processing tablet-mode events on convertible or detachable devices. If two events are processed concurrently, the input device may be...

CVE-2026-64593

A flaw was found in the btrfs filesystem of the Linux kernel. A local user could trigger a system crash by attempting to perform a trim operation on a storage device that was previously unavailable but has since reconnected and is not writeable. This issue arises from a synchronization problem...

CVE-2026-64591

A flaw was found in the Linux kernel's Intel IOMMU driver. This issue occurs because the driver attempts to disable I/O Page Fault IOPF handling for devices that never had it enabled, specifically when Shared Virtual Addressing SVA is used on hardware that does not support the PCI Page Request...

CVE-2026-64590

A flaw was found in the Linux kernel's dma-buf subsystem, specifically within the udmabuf component. When the CONFIGDMAAPIDEBUGSG option is enabled, importing a udmabuf into a Direct Rendering Manager DRM driver can trigger a spurious warning about overlapping cacheline mappings. This occurs...

CVE-2026-23398

CVE-2026-23398 Linux Kernel icmptagvalidation NULL Pointer Dereference Remote DoS Description icmptagvalidation in net/ipv4/icmp.c dereferences inetprotosproto without a NULL check. A remote attacker can send a single crafted ICMP Fragmentation Needed packet with an unregistered inner protocol...

CVE-2026-89855

A flaw was found in the Linux kernel's scsi: qla2xxx component. A local attacker could exploit a race condition in the flash version read handler. By concurrently triggering a sysfs reset operation and other flash operations, an attacker could corrupt flash register reads. This could lead to data...

CVE-2026-89790

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition can occur during IPv6 multipath route rebalancing, where a concurrent update can lead to a divide-by-zero error. This vulnerability can cause the kernel to crash, resulting in a Denial of Service DoS for the affect...

CVE-2026-89784

A flaw was found in the Linux kernel's SUNRPC component. When an in-kernel RPC service registers with the local rpcbind under memory pressure, a failure in memory allocation can lead to a NULL pointer being dereferenced. This unchecked NULL pointer can cause the kernel to crash, resulting in a...

CVE-2026-89577

A flaw was found in the Linux kernel's device mapper I/O dm-io and RAID1 dm-raid1 components. Incorrect error handling for non-retryable errors such as BLKSTSNOTSUPP and BLKSTSINVAL could lead to misbehavior when a user utilizes unaligned bio vectors on dm-raid1.
