Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

A flaw was discovered in the exFAT driver of the Linux kernel. The vulnerability resides in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long...

Astra Linux – Vulnerability in Linux

In the file drivers/pci/hotplug/rpadlpar/sysfs.c within the Linux kernel up to version 5.11.8, the RPA PCI Hotplug driver suffers from a user-tolerable buffer overflow when writing a new device name to the driver from user space. This allows user space to write data directly to the kernel stack...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: powerpc/lib: Validate size for vector operations Some parts of the fp/vmx code in sstep.c assume a certain maximum size for the instructions being emulated. However, the size of these operations is determined separately in the...

FreeBSD Security Advisory - FreeBSD-SA-26:18.setcred

FreeBSD Security Advisory - The setcred2 system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the...

FreeBSD -- Stack buffer overflow via setcred(2)

Problem Description: The setcred2 system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the supplied li...

CVE-2026-23404

A flaw was found in the Linux kernel's AppArmor security module. A local user could trigger a denial of service by initiating a recursive profile removal operation with deeply nested profiles. This recursive process can lead to kernel stack exhaustion, causing the system to crash...

CVE-2026-23335

CVE-2026-23335: Linux kernel RDMA/irdma create_user_ah() leak resolved. Root cause: the irdma_create_ah_resp struct contained 4 bytes (rsvd) that were never zeroed, leaking stack memory prior to ib_respond_udata(). Affected code paths thus exposed uninitialized stack content (4 bytes) in the resp...
