Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs-schemes: protect memcgpath kfree with damonsysfslock Patch series "mm/damon/sysfs-schemes: fix use-after-free for memcgpath". Reads of 'memcgpath' and 'path' files in DAMON sysfs...

CVE-2026-98659

A flaw was found in the Linux kernel's ROHM BM1390 Industrial I/O IIO sensor driver. The driver fails to propagate error status codes when a read operation fails, unconditionally returning success. A local user querying the sensor can receive invalid or uninitialized measurement data without an...

CVE-2026-98658

A flaw was found in the Linux kernel's aw96103 proximity sensor driver. This vulnerability can lead to a Denial of Service DoS or kernel information disclosure via an out-of-bounds memory read. The issue occurs because the driver's firmware parser does not properly validate the data length...

CVE-2026-98657

A flaw was found in the Linux kernel's PulsedLight LIDAR sensor driver. When device initialization fails during power management setup, the driver fails to properly unregister the device before releasing its allocated memory. This leaves active system interfaces pointing to released memory,...

CVE-2026-98656

A flaw was found in the Linux kernel's Industrial I/O IIO subsystem. A race condition occurs when deferred background tasks are not canceled prior to releasing trigger device structures, allowing a worker thread to access memory after it has been freed. A local user could exploit this flaw during...

CVE-2026-98655

A flaw was found in the Linux kernel. An unprivileged local user could exploit this vulnerability to cause an information disclosure, bypassing Kernel Address Space Layout Randomization KASLR, a security feature that randomizes kernel memory addresses to hinder exploitation. By opening performanc...

CVE-2026-98653

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM subsystem on s390 architectures. In nested virtualization environments, the kernel can erroneously pass an unhandled memory fault error to host userspace when shadowing nested guest memory pages that are not yet mapped. A gue...

CVE-2026-98652

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM subsystem for the s390 architecture. A missing synchronization lock during status storing operations allows a local user with virtual machine management privileges to trigger a race condition. This flaw can lead to kernel...

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: 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...

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...

K000163828: Linux kernel vulnerability CVE-2026-46125

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: remove station if connection prep fails If connection preparation fails for MLO connections, then the interface is completely reset to non-MLD. In this case, we must not keep the...

K000163827: Linux kernel vulnerability CVE-2026-46124

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: isofs: validate block number from NFS file handle in isofsexportiget isofsfhtodentry and isofsfhtoparent pass an attacker- controlled block number ifid-block or ifid-parentblock from the NFS file...

kernel: ALSA: seq: close a re-opened queue timer in the destructor

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer component. An unprivileged local user with access to the sound device can exploit a timing window during the cleanup of a queue timer. This allows the user to re-open a timer that has already been closed,...

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...
