Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: scsi: hisisas: The pointer to debugfsdir is set to NULL after removing debugfs. If init debugfs fails during device registration due to a memory allocation failure, the function debugfsremoverecursive is called. However, debugfsd...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in the ksmbd component of the Linux kernel. A race condition between the smb2 close operation and logoff in multi-channel connections could lead to a use-after-free issue...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel up to 5.15.2, hwatlutilsfwrpcwait in drivers/net/ethernet/aquantia/atlantic/hwatl/hwatlutils.c allows an attacker who can introduce a crafted device to trigger an out-of-bounds write by using a crafted length value...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: rnbd-srv: Zero the rsp buffer before using it. Before using the data buffer to send back the response message, completely zero it. This prevents any stray bytes from being picked up by the client side when messages are exchanged...

kernel: drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl()

A flaw was found in the Linux kernel. Specifically, within the drm/xe graphics driver, two error handling issues in the xeexecqueuecreateioctl function could lead to memory corruption. This could result in a dangling pointer or a use-after-free vulnerability. A local attacker could potentially...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dm: Clearing the clone request’s bio pointer when the last cloned bio is freed It has been observed that stale values of rq-bio can lead to double initialization of cloned bios in request-based device-mapper targets, resulting in...

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: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

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: rtnetlink: add missing netlink_ns_capable() check for peer netns

A flaw was found in the Linux kernel's rtnetlink component. An unprivileged local user, leveraging a user namespace, can exploit a missing CAPNETADMIN capability check in the rtnlnewlink function. This allows the user to create paired network devices in arbitrary network namespaces, including the...

kernel: KVM: x86: Check for invalid/obsolete root *after* making MMU pages available

A flaw was found in KVM in the Linux kernel. This vulnerability occurs due to improper validation of memory management unit MMU page roots after these pages are made available. An attacker could exploit this by triggering a scenario where KVM attempts to map memory into an invalid root, causing...

kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...

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...

CVE-2026-64460

A flaw was found in the Linux kernel's PCI/IOV subsystem. When a PCI device fails to respond during a power state transition, the kernel's Virtual Function VF Resizable Base Address Register BAR restoration process can attempt to access memory outside of its allocated bounds. This out-of-bounds...
