Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

Guests running on Arm can cause Denial of Service DoS attacks on Dom0 through PV devices. When mapping memory pages of guests on Arm, Dom0 uses an rbtree to keep track of the foreign mappings. The update of this rbtree does not always occur completely with the relevant lock held, resulting in a...

CVE-2026-47491

A flaw was found in nvidia-driver. A local unprivileged attacker can trigger the improper release of memory resources in the kernel mode layer, leaving a memory mapping accessible after the underlying memory is reused. A successful exploit could allow an attacker to achieve privilege escalation,...

CVE-2026-102820

pageant provides a PageantStream type that implements AsyncRead and AsyncWrite traits and can be used to talk to a running Pageant instance. Prior to pageant 0.2.3, the Windows pageant crate's pageant/src/wmmessage.rs MemoryMap::read function trusts a peer-controlled u32 response length supplied...

PT-2026-102804

Name of the Vulnerable Software and Affected Versions pageant versions prior to 0.2.3 Description The MemoryMap::read function in the pageant/src/wmmessage.rs file trusts a peer-controlled u32 response length provided via the 8192-byte shared-memory mapping accessed by AgentClient::connect pagean...

CVE-2026-98140

A flaw was found in the Linux kernel's NTFS file system. A local user could trigger this vulnerability during error handling in Master File Table MFT write operations, where temporary kernel memory mappings fail to be released properly. Because these local memory mappings require strict ordering,...

CVE-2026-97931 ALSA: us122l: Prevent write upgrades for read mappings

In the Linux kernel, the following vulnerability has been resolved: ALSA: us122l: Prevent write upgrades for read mappings The hwdep mmap callback rejects read-buffer mappings that are initially writable, but leaves VMMAYWRITE set on mappings created with PROTREAD. A process that can open the hwd...

CVE-2026-97912: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Ensure SRAM size is 0 on mapping failure On a mapping failure of the SRAM, the SRAM size is left as non-zero. The probe will succeed as the error return is not checked since having SRAM is not a hard requirement. T...

SUSE CVE-2026-90341

In the Linux kernel, the following vulnerability has been resolved: firmware: coreboot: Validate table bounds The existing coreboottablepopulate bounds checks limit individual entries to the mapped length. However, coreboottableprobe replaces the platform resource length with header and table siz...

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

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: cmd-db: Maps shared memory as WC, not WB. Linux does not write to the cmd-db region. This memory region is protected from writing by XPU. XPU may sometimes falsely detect a clean cache eviction as a “write” to the...

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

In the Linux kernel, the following vulnerability has been resolved: regulator: stm32-pwr: Fix for the ofiomap leak. Suggestions: - In the file drivers/regulator/stm32-pwr.c, line 166 of stm32pwrregulatorprobe: The “base” from the ofiomap function is not released when the probe function fails. - T...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/pagetablecheck: A crash occurred when checking ZONEDEVICE. Not all pages apply to the pgtable check. An example is ZONEDEVICE pages: they directly map PFNs, and they never allocate pageext, even if there’s a struct page around...

Astra Linux – Vulnerability in gst-plugins-good1.0

DOS: Potential heap overwrite during MKV demuxing using Zlib decompression. Integer overflow occurs in the matroskademux element within the gstmatroskadecompressdata function, which can cause a segfault—or potentially a heap overwrite, depending on the libc and operating system. Depending on the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/shmem-helper: Fixed the BUGON in mmapPROTWRITE, MAPPRIVATE. A lack of check for copy-on-write COW mapping in drmgemshmemmmap allows users to call mmap with PROTWRITE and MAPPRIVATE flags, causing a kernel panic due to BUGON i...

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

In the Linux kernel, the following vulnerabilities have been resolved: drm/i915/gem: Fixed the calculation of the boundaries of virtual memory mappings. The current approach calculates the size of the mapped area as the smaller value between the requested size and the actual size, without...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ARM: 9359/1: flush: check if the folio is reserved for no-mapping addresses Since commit a4d5613c4dc6 “arm: extend pfnvalid to take into account freed memory map alignment” changes the semantics of pfnvalid to check the presence ...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Corrected the migration DMA map direction The SVM DMA device map direction should be set the same as the DMA unmap setting; otherwise, the DMA core will report the following warning. Before finalizing this solution,...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ACPI: Tables: FPDT: Do not call acpiosmapmemory on an invalid physical address. On a Packard Bell Dot SC Intel Atom N2600 model, there is an FPDT table containing invalid physical addresses, with high bits set that fall outside t...

Linux kernel vmclock_miscdev_mmap Heap Buffer Overflow DoS

The vulnerability of the vmclockmiscdevmmap function in the drivers/ptp/ptpvmclock.c file of Linux kernel operating systems is related to incorrect execution permissions. Exploiting this vulnerability can allow an attacker to compromise the confidentiality, integrity, and accessibility of protect...

PT-2026-83024

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the vmclock miscdev mmap function within the drivers/ptp/ptp vmclock.c file. This flaw allows read-only mappings to become writable, which may impact the...

CVE-2026-80582

A flaw was found in the Linux kernel's drm/shmemhelper component. This vulnerability arises from insufficient boundary checks when handling large memory pages. An attacker could potentially trigger an attempt to map memory outside its designated area. This improper memory handling could lead to a...
