CVE-2026-68234

A flaw was found in the Linux kernel's drm/amdgpu component. The amdgpubocreatereserved function unconditionally increments a pin counter for a Buffer Object BO even if it is already pinned. This occurs when the function is called multiple times with the same BO, such as during firmware buffer...

CVE-2026-68379

A flaw was found in the Linux kernel's TCP implementation. A reference leak in TIMEWAIT sockets can occur upon a PSP Policy Security Policy failure in both IPv4 and IPv6 receive paths. This vulnerability can lead to a memory leak of tcptwbucket structures, potentially resulting in a Denial of...

CVE-2026-68168

A flaw was found in the Linux kernel's Andrew File System AFS component. The system's directory removal function, afseditdirremove, incorrectly manages memory blocks, specifically block 0. This improper handling could lead to an unstable system state or data integrity issues during directory...

CVE-2026-68101

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. During the allocation or deallocation of a user pointer buffer object, a critical reference to its virtual memory object can become unavailable. This improper handling of memory submissions could lead to system instability or a denial ...

CVE-2026-68236

A flaw was found in the Linux kernel's drm/amd/display component. Specifically, within the dmupdatecrtcstate function, a stream pointer is released but not subsequently set to NULL. This can lead to a double release of the same pointer if an error occurs later in the process, creating a...

EUVD-2026-56115

A vulnerability has been identified in Solid Edge SE2025 All versions V225.0 Update 15, Solid Edge SE2026 All versions V226.0 Update 7. The affected applications contains an out of bounds read vulnerability while parsing specially crafted PAR files. This could allow an attacker to execute code in...

github.com/prometheus/prometheus: Prometheus: Denial of Service via uncontrolled memory allocation in remote read endpoint

A flaw was found in Prometheus. An unauthenticated attacker can exploit the remote read endpoint /api/v1/read by sending a specially crafted, small snappy-compressed payload. This payload causes a disproportionately large memory allocation, leading to memory exhaustion and a Denial of Service DoS...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

CVE-2026-68088

A flaw was found in the Linux kernel's RNDIS Remote Network Driver Interface Specification gadget function. A missing length check for BufLength and BufOffset parameters within the rndisqueryresponse function could allow a malicious actor to provide specially crafted input. This could lead to...

CVE-2026-68181

A flaw was found in the Linux kernel's mei bus component. A use-after-free vulnerability exists in the meiclbusdevrelease function. This flaw, caused by improper synchronization during cleanup, could lead to memory corruption and system instability...

CVE-2026-68212

A flaw was found in the Linux kernel's saa7134 media driver. During device probing, the saa7134videoinit1 function does not properly check return values from memory allocation, leading to unreleased memory and invalid page tables. This can result in memory leaks and the potential use of...

CVE-2026-68245

A flaw was found in the drm/amdgpu component of the Linux kernel. A use-after-unlock vulnerability exists where a virtual machine VM pointer is dereferenced after its protective lock has been released. This allows the pointer to be modified, potentially leading to memory corruption. An attacker...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...

kernel: mm/slab: do not limit zeroing to orig_size when only red zoning is enabled

A flaw was found in the Linux kernel's memory management subsystem. This issue occurs when the kernel's memory allocator attempts to zero out newly allocated memory, but an incorrect check prevents the full memory region from being cleared under specific configurations. This can lead to memory no...

kernel: net: openvswitch: reject oversized nested action attrs

A flaw was found in Open vSwitch in the Linux kernel. Improper handling of oversized nested action attributes can lead to a truncated length field, which could be exploited by a local attacker to alter kernel memory. This alteration might result in the disclosure of sensitive information or a loc...

kernel: cxl/port: Fix use after free of parent_port in cxl_detach_ep()

In the Linux kernel, the following vulnerability has been resolved: cxl/port: Fix use after free of parentport in cxldetachep cxldetachep is called during bottom-up removal when all CXL memory devices beneath a switch port have been removed. For each port in the hierarchy it locks both the port a...

pyasn1: pyasn1: Denial of Service via crafted ASN.1 REAL values

A remote attacker can exploit this by providing specially crafted BER/CER/DER-encoded ASN.1 data with a large exponent in the REAL value. When the application subsequently prints, logs, compares, or performs arithmetic on the decoded value, this can cause excessive CPU and memory consumption,...
