CVE-2026-98511

A flaw was found in the Linux kernel's Nouveau GPU driver. When attempting to re-pin a memory buffer into an incompatible memory domain, the driver rejects the request but fails to prevent an increment of the buffer's pin count. Because callers do not unpin after an error, this causes an unbalanc...

CVE-2026-98447

A flaw was found in the Linux kernel's XFS file system. This vulnerability allows a local attacker to cause a Denial of Service DoS or potentially compromise the system through memory corruption. During the formatting of realtime reference count metadata, the kernel incorrectly calculates the...

kernel: ipv6: validate extension header length before copying to cmsg

A flaw was found in the Linux kernel's IPv6 networking stack. An unprivileged local user could exploit a vulnerability in how IPv6 extension header lengths are handled. By manipulating these headers using nftables, an attacker can trigger an out-of-bounds read, leading to information disclosure...

kernel: ALSA: 6fire: fix use-after-free on disconnect

A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...

kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()

A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...

kernel: crypto: pcrypt - Fix handling of MAY_BACKLOG requests

A flaw was found in the Linux kernel's pcrypt component. This vulnerability involves how the system handles certain requests, specifically MAYBACKLOG requests, which can indicate a temporary busy state. If not properly managed, the system's processing of these requests could lead to resource...

kernel: Linux kernel: Denial of Service in qla2xxx SCSI driver due to improper command handling after chip reset

A flaw was found in the Linux kernel's qla2xxx SCSI driver. This vulnerability occurs when commands sent to the firmware FW are not properly cleared after a chip reset. A local attacker could exploit a race condition during direct memory access DMA unmapping, leading to a kernel panic. This can...

SUSE-SU-2026:4734-1 Security update for the Linux Kernel (Live Patch 36 for SUSE Linux Enterprise 15 SP5)

This update for the SUSE Linux Enterprise Kernel 5.14.21-150500.55.141 fixes various security issues: The following security issues were fixed: - CVE-2026-53131: netfilter: require Ethernet MAC header before using ethhdr bsc1269775. - CVE-2026-63794: KVM: SVM: Fix page overflow in sevdbgcrypt for...

CVE-2026-98505

A flaw was found in the Linux kernel. A race condition within the Data Access Monitor DAMON subsystem allows hardware-driven page table updates to be lost during the monitoring of huge memory pages. A local user running processes monitored by DAMON can trigger concurrent memory operations,...

CVE-2026-98509

A flaw was found in the Linux kernel's virtio graphics processing unit virtio-gpu driver. A local user can cause a Denial of Service DoS by triggering a kernel memory leak during graphics command buffer processing. When invalid submission parameters are provided, the driver's error-handling path...

CVE-2026-98502

A flaw was found in the Linux kernel's ALPS Human Interface Device HID driver. The driver fails to properly unregister and release a secondary input device when the hardware is removed. A local user could exploit this issue by repeatedly disconnecting the device, causing a memory leak that can le...

CVE-2026-98508

A flaw was found in the Linux kernel's VirtIO GPU driver. This flaw allows a local user to cause a denial of service DoS by triggering a kernel crash. Under memory pressure, the driver fails to verify whether fence memory allocation succeeds during graphics command submission, leading to an...

CVE-2026-98506

A flaw was found in the Linux kernel's HugeTLB Huge Translation Lookaside Buffer subsystem. This flaw allows a local user to cause a Denial of Service DoS by triggering the dissolution of gigantic memory pages that lack runtime support. Because the kernel fails to verify runtime support before...

CVE-2026-98507

A flaw was found in the Linux kernel's memory management subsystem. Due to a missing synchronization barrier when preparing anonymous virtual memory areas, concurrent memory operations can be reordered. A local attacker can exploit this race condition by running concurrent threads on adjacent...

CVE-2026-98504

A flaw was found in the Linux kernel's PCI subsystem. When generating dynamic Open Firmware OF device tree properties, the kernel fails to verify that a subordinate bus exists for a PCI bridge before accessing its configuration. A local attacker or physical device configuration can trigger this...

CVE-2026-98503

A flaw was found in the Linux kernel's packet socket implementation. A local user can cause a Denial of Service DoS or system instability by triggering premature reuse of transmit ring buffer slots while packet data is still in flight. Because these shared memory slots may be released and reused...

CVE-2026-98501

A flaw was found in the Linux kernel's Alps Human Interface Device HID driver. If registration of an input device fails during configuration, the driver frees the device memory while communication channels are already active, leaving a dangling reference. An attacker capable of attaching a...

CVE-2026-98445

A flaw was found in the Linux kernel's XFS file system. A local user could cause a Denial of Service DoS by triggering an online file system repair under low-memory conditions. When a memory allocation failure occurs during repair block reservation, the kernel cannot cleanly recover from the erro...

CVE-2026-98443

A flaw was found in the Linux kernel's XFS file system. Improper pointer handling during the recovery of unlinked files can cause a use-after-free condition, where the operating system attempts to access memory after it has already been freed. A local user capable of mounting a specially crafted...

CVE-2026-98444

A flaw was found in the Linux kernel's XFS file system. When flushing disk quota records, the kernel fails to release the quota flush lock if an associated buffer cannot be retrieved. A local user could trigger this condition to cause a system deadlock, resulting in a Denial of Service DoS...
