CVE-2026-63817

A flaw was found in the Linux kernel's F2FS file system. When the compresscache mount option is disabled, a corrupted directory entry could point to an invalid inode number. The system incorrectly processes this as a valid internal inode, bypassing critical validation checks. This vulnerability...

CVE-2026-63816

A flaw was found in the f2fs Flash-Friendly File System component of the Linux kernel. This use-after-free UAF vulnerability occurs during garbage collection operations when handling Copy-On-Write COW files. A local attacker could exploit this by triggering garbage collection, leading to a...

CVE-2026-63815

A flaw was found in the Linux kernel's f2fs Flash-Friendly File System component. When processing a specially crafted f2fs filesystem image, an attacker can trigger an out-of-bounds read. This occurs because the system incorrectly validates the size of inline extended attributes, leading to...

CVE-2026-63814

A flaw was found in the Linux kernel's Flash-Friendly File System f2fs. A local attacker could exploit improper validation of Access Control List ACL entry sizes to cause a memory corruption, leading to a system crash or denial of service. This occurs when malformed ACL entries cause the system t...

CVE-2026-63810

A flaw was found in the Linux kernel. This vulnerability allows a local user to cause a system crash, leading to a Denial of Service DoS, by attempting to mount the internal bdev pseudo-filesystem. This action triggers a null pointer dereference within the kernel, which could also potentially be...

CVE-2026-63806

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A malicious guest operating system can trigger a host kernel crash, leading to a Denial of Service DoS. This occurs when the guest performs a specific memory write operation that causes an unaligned memory access...

CVE-2026-64060

A flaw was found in the netfs component of the Linux kernel. An issue in the error handling of the netfswritebegin function can lead to a leak of a request resource. This occurs when an error is returned from netfswaitforread, preventing the proper release of the resource. This resource leak may...

CVE-2026-63796

A flaw was found in the Linux kernel's Oracle Cluster File System 2 ocfs2. A local attacker could craft a malicious group bitmap descriptor that claims a size exceeding the physically allocated bitmap bytes. This improper input validation allows subsequent operations to read or write beyond the...

CVE-2026-63805

A flaw was found in the Linux kernel's cryptographic module. An issue with how the nxcryptoctxexit function handles arguments can cause the kernel to crash. This vulnerability could be exploited by a local user, leading to a Denial of Service DoS for the affected system...

CVE-2026-64142

A flaw was found in the Linux kernel's ksmbd component. Two race conditions in the ksmbddurablescavenger function can lead to list corruption and a Use-After-Free UAF vulnerability. A remote attacker could potentially exploit these race conditions during durable handle scavenging and lookup...

CVE-2026-63799

A flaw was found in the Linux kernel's scheduler component. A local attacker could exploit an out-of-bounds write vulnerability during the creation or execution of a new task in per-CPU mode, specifically when an internal identifier is unassigned. This can lead to a bounded memory corruption, whe...

CVE-2026-63798

A flaw was found in the Linux kernel's irqchip/imgpdc driver. This vulnerability occurs because the driver fails to properly free allocated resources and remove interrupt handlers when the driver is removed. This oversight can lead to a use-after-free condition, where the system attempts to acces...

CVE-2026-64164

A flaw was found in the Linux kernel's btrfs filesystem tracepoints. The btrfssyncfile trace event, when called in an atomic context, attempts to perform an operation that can cause the system to sleep. This can lead to a kernel crash, resulting in a Denial of Service DoS for the affected system....

CVE-2026-53403

A flaw was found in the Linux kernel's framebuffer device fbdev subsystem. When a new modelist is set from userspace, the fbnewmodelist function fails to ensure that the current framebuffer mode remains valid within the updated list. This can lead to a null-pointer dereference if a console attemp...

CVE-2026-63793

A flaw was found in the Linux kernel's NTFS file system driver. This vulnerability, a use-after-free, arises from insufficient protection during concurrent operations on the volume label. A local attacker could exploit this by simultaneously setting and getting the file system label, which may le...

CVE-2026-53401

A flaw was found in the Linux kernel's omapfb display driver. A race condition in the omapfbmmap function, which manages memory mapping, allows for concurrent operations that can lead to a use-after-free vulnerability. This could enable a local attacker to access freed physical memory, potentiall...

CVE-2026-64186

A flaw was found in the Linux kernel's AMD IOMMU debugfs. Improper handling of user-provided input in the iommummiowrite and iommucapabilitywrite functions can lead to an out-of-bounds memory access. This vulnerability could allow a local attacker to potentially cause a denial of service or...

CVE-2026-64087

A flaw was found in the Linux kernel's pmbus/adm1266 driver. A malformed response from a hardware monitoring device could cause the driver to read beyond the allocated memory buffer. This out-of-bounds read can lead to system instability or denial of service...

CVE-2026-53389

A flaw was found in the Linux kernel's TCP Authentication Option TCP-AO implementation. When a TCP-AO key is deleted asynchronously, the system fails to clear pointers to the freed memory. This can allow an attacker to access previously freed memory, potentially leading to information disclosure ...

CVE-2026-53390

A flaw was found in the Linux kernel's ksmbd component. An authenticated client can exploit an out-of-bounds read vulnerability in the smbcheckpermdacl function by providing a specially crafted Access Control Entry ACE. This crafted ACE, when processed during an access check on a share that uses...
