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...

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...

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: 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,...

This can lead to memory no...

kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation

A flaw was found in the Linux kernel's AMD display component. This vulnerability arises from incorrect validation of display mode changes during Display Stream Compression DSC processing. A local attacker could exploit this by initiating specific display configuration changes, which may lead to a...

kernel: ipc: limit next_id allocation to the valid ID range

A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...

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: shmem: fix recovery on rename failures

A flaw was found in the Linux kernel's shmem tmpfs filesystem rename operation. Under severe memory pressure, the mapletree insertion used during file rename can fail, and the error recovery path does not properly handle this failure. This can leave the filesystem directory offset tree in an...

DEBIAN-CVE-2026-71218

A flaw was found in iperf3. A remote unauthenticated attacker can exploit a vulnerability in the JSONread function, which accepts a peer-controlled message length and allocates memory without an upper bound. This allows the attacker to trigger excessive memory consumption, leading to a Denial of...

CVE-2026-15567

A flaw was found in Wildfly. A remote unauthenticated attacker can trigger OutOfMemoryError as CSIv2Util's GSS token decoder reads an attacker-controlled length field without bounds checking and attempts to allocate a byte array of that size...

DEBIAN-CVE-2026-15565

A flaw was found in Undertow. A remote attacker can cause Out of Memory on websockets endpoint without authentication on any @ServerEndpoint class that has any @OnMessage method. This allows an attacker to cause Denial of Service attack without authentication and using only a standard WebSocket...
