CVE-2026-64308

A flaw was found in the Linux kernel's crypto: ccp module, which handles AMD Secure Encrypted Virtualization SEV and Secure Nested Paging SNP features. A local user, by sending specific commands through the /dev/sev interface, could exploit improper initialization handling. If SEV initialization...

CVE-2026-64291

A flaw was found in the Linux kernel's iommufd subsystem. A local user could exploit this vulnerability by allocating excessively large event queues, leading to the exhaustion of kernel memory. This can result in a Denial of Service DoS for the system...

CVE-2026-64419

A flaw was found in the Linux kernel. A local user could trigger a system crash by reading a specific debugfs "count" file related to memory management. This issue arises because a function attempts to perform an operation that can cause it to pause sleep while holding a critical system lock, whi...

CVE-2026-64298

A flaw was found in the Linux kernel's NFSv4 implementation. A local user could exploit a vulnerability where opening a file with OTRUNC truncate and ORDONLY read-only flags would bypass the necessary write permission checks. This oversight allows an attacker to truncate a file without having...

CVE-2026-64280

A flaw was found in the Linux kernel's dfl-afu FPGA driver. A local user could exploit this vulnerability by providing an excessively large length value during Direct Memory Access DMA mapping operations. The system incorrectly truncates this value, leading to memory corruption. This could allow ...

CVE-2026-64292

A flaw was found in the Linux kernel's iommufd component. A local user can exploit this vulnerability by allocating large veventq queues, which are processed inside a spinlock. This can lead to the exhaustion of atomic memory reserves, resulting in a Denial of Service DoS condition...

CVE-2026-64543

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. A use-after-free vulnerability exists in the tipcdiscrcv function, where the discoverer object can be prematurely freed while still being referenced. An unprivileged local user can exploit this flaw by...

CVE-2026-64551

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP. This vulnerability allows a remote attacker or a local unprivileged user to potentially access and disclose sensitive information. By sending a malformed error message, the system can be tricked into reading and the...
