CVE-2026-98651

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for the s390 architecture. This vulnerability occurs when memory management routines fail to properly validate an empty pointer reference during storage key operations. A local attacker could exploit this flaw to...

CVE-2026-98649

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem on s390 architectures. A local attacker can exploit this vulnerability to cause a Denial of Service DoS or memory corruption by triggering a race condition during guest memory page destruction. This issue occurs...

CVE-2026-98648

A flaw was found in the Linux kernel's IBM s390 Ultravisor subsystem. When searching stored secrets on systems holding more than 85 secrets, the kernel incorrectly references the total secret count instead of the number of items stored in the current memory page. A local user can exploit this...

kernel: inet: frags: strip GSO state from fragments before reassembly

A flaw was found in the Linux kernel's network fragment reassembly process. An unprivileged local user, or a guest in a virtualized environment, could craft specially formed IPv4 or IPv6 network fragments that incorrectly retain Generic Segmentation Offload GSO state after reassembly. This...

kernel: vfio/pci: clear vdev->msi_perm after freeing it on init failure

A flaw was found in the Linux kernel's vfio/pci component. During device initialization, a memory pointer is not properly cleared after being freed, leading to a use-after-free and double-free vulnerability. A local attacker could exploit this flaw to cause a system crash, resulting in a denial o...

kernel: ipv4: raw: reject IP_HDRINCL packets with ihl < 5

A flaw was found in the Linux kernel's handling of IPv4 raw sockets. An unprivileged attacker with CAPNETRAW capabilities can craft and inject a malformed IPv4 packet with an invalid Internet Header Length IHL. This can lead to an out-of-bounds memory access when the packet is processed by certai...

kernel: xfs: bounds-check buffer log item's dirty bitmap

A flaw was found in the Linux kernel's XFS filesystem. A local attacker, by mounting a specially crafted XFS image, could trigger an out-of-bounds write during log recovery. This vulnerability allows for kernel heap corruption, which could lead to a denial of service or potentially arbitrary code...
