This vulnerability can lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-63877

A flaw was found in the Linux kernel's serial DZ driver. During the initialization of the first serial port, a null pointer dereference occurs because a pointer to the port's parent device is incorrectly derived from a null value. This vulnerability can lead to a system crash, resulting in a Deni...

SUSE CVE-2026-63991

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: 6lowpan: check skbclone return value in sendmcastpkt The skbclone function can return NULL if memory allocation fails. sendmcastpkt calls skbclone without checking the return value, which can lead to a NULL pointer...

CVE-2026-63973

A flaw was found in the Linux kernel's mana network driver. During certain error handling scenarios, specifically when network queue allocation fails, the driver attempts to access memory that has already been freed. This can lead to a NULL pointer dereference, causing the system to crash and...

CVE-2026-64207

A flaw was found in the Linux kernel's DualPI2 Dual-rate PI2 queue discipline. This vulnerability arises from incorrect accounting of Generic Segmentation Offload GSO backlog, where the parent queue such as QFQ - Hierarchical Fair Queueing miscalculates the number of queued packets. This...

CVE-2026-64187

A flaw was found in the Linux kernel's XFS filesystem log recovery component. A local attacker could exploit this vulnerability by crafting a malicious XFS log. When the system attempts to recover from this log, it triggers a null-pointer dereference, which can lead to a system crash. This result...
