CVE-2026-74439

A flaw was found in the Linux kernel's Input/Output Memory Management Unit IOMMU subsystem. The devicepasidtableteardown function incorrectly clears a scalable-mode context entry while its 'Present' bit remains set. This creates a window where the hardware can access a partially cleared entry,...

CVE-2026-74438

A flaw was found in the Linux kernel's sun4i-ss cryptographic random number generator RNG. This component contains multiple vulnerabilities, including a buffer overflow in the sun4issprngseed function that could lead to a denial of service. Furthermore, the sun4issprnggenerate function may not...

USN-8664-1: Linux kernel (NVIDIA BaseOS) vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...

USN-8664-1 linux-nvidia-bos vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...

CVE-2026-74436

A flaw was found in the Linux kernel. A synchronization issue in the rxrpc component, specifically between rxrpckernelchargeaccept and rxrpcdiscardprealloc, can lead to a use-after-free vulnerability. A local attacker could potentially exploit this flaw, causing a kernel preallocation worker to...

USN-8663-1: Linux kernel (NVIDIA) vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...

CVE-2026-74435

A flaw was found in the rxrpc subsystem of the Linux kernel. This vulnerability occurs when the rxrpcverifydata function fails to allocate a necessary buffer if the incoming data length is zero. An attacker could exploit this by sending specially crafted network packets, leading to a NULL pointer...

CVE-2026-74434

A flaw was found in the Linux kernel's rxrpc subsystem. When an out-of-band OOB message is read using the MSGPEEK flag in the rxrpcrecvmsgoob function, the message is incorrectly left on one queue while also being added to another. This can lead to the message being freed twice when the socket is...

CVE-2026-74431

A flaw was found in the Linux kernel's rxrpc network protocol implementation. This vulnerability could allow an attacker to trigger an infinite loop within the rxrpcrecvmsg function by manipulating out-of-band OOB queue handling. This could lead to a Denial of Service DoS condition, making the...

CVE-2026-74430

A flaw was found in the Linux kernel's rxrpc component. A remote attacker could send a specially crafted ACKALL packet that bypasses state validation. This improper handling of forged packets can lead to a null-pointer dereference, causing a Denial of Service DoS by crashing the system...
