kernel: Linux kernel: Memory corruption in Squashfs due to incorrect block size calculation

A flaw was found in the Linux kernel's Squashfs filesystem. A local attacker can exploit this vulnerability by simultaneously mounting a Squashfs filesystem and issuing a specific input/output control ioctl command. This can lead to an incorrect block size calculation, causing a shift-out-of-boun...

CVE-2025-54514

Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity...

CVE-2025-27535

Exposed ioctl with insufficient access control in the firmware for some IntelR Ethernet Connection E825-C. before version NVM ver. 3.84 within Ring 0: Bare Metal OS may allow a denial of service. System software adversary with a privileged user combined with a high complexity attack may enable...

CVE-2025-22885

Improper buffer restrictions in the firmware for the TDX Module may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack...

kernel: Linux kernel: Out-of-bounds write in Bluetooth MGMT can lead to information disclosure and denial of service

A flaw was found in the Linux kernel's Bluetooth management MGMT subsystem. A local attacker could exploit an out-of-bounds OOB write vulnerability in the parseadvmonitorpattern function. This occurs when user-controlled input for the length variable exceeds the buffer's capacity during a copy...

kernel: Linux kernel: Denial of Service due to data race in vmalloc's show_numa_info function

A flaw was found in the Linux kernel. A data race vulnerability exists in the shownumainfo function within the mm/vmalloc component. This occurs because the m-private memory is accessible to multiple central processing units CPUs simultaneously, leading to inconsistent data reads and writes. A...

kernel: Linux kernel: Denial of Service via out-of-bounds read in USB configuration parsing

A flaw was found in the Linux kernel's USB core configuration parsing. Specifically, the usbparsessendpointcompanion function incorrectly checks the descriptor type before its length, which can lead to reading data beyond the intended buffer. This out-of-bounds read vulnerability could allow a...

kernel: Linux kernel use-after-free in eventpoll

A flaw was found in the Linux kernel's eventpoll epoll mechanism. A local attacker could exploit a use-after-free vulnerability due to incorrect handling of the 'ep' refcount while the 'ep' mutex is still held. This can lead to memory corruption, potentially allowing the attacker to achieve...

kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling

A flaw was found in the Linux kernel's iouring/net component. This vulnerability arises when ring provided buffers are partially committed during network operations, particularly when MSGWAITALL is enabled or with streaming sockets. A local attacker could exploit this by causing multiple socket...

GnuPG: GnuPG: Stack-based buffer overflow in tpm2daemon allows arbitrary code execution

A flaw was found in GnuPG. This vulnerability, a stack-based buffer overflow, occurs in the tpm2daemon component when processing PKDECRYPT commands for cryptographic keys secured by a Trusted Platform Module TPM. A local attacker could exploit this to execute unauthorized code, potentially gainin...

USN-8044-1 alsa-lib vulnerability

It was discovered that alsa-lib incorrectly handled the topology mixer control decoder. A local attacker could use a specially crafted topology file to cause alsa-lib to crash, resulting in a denial of service, or possibly execute arbitrary code...

kernel: Linux kernel erofs: Use-After-Free due to device type mismatch

A flaw was found in the Linux kernel's erofs filesystem. A local attacker could exploit a use-after-free UAF vulnerability by mounting an erofs filesystem with a specific configuration where the primary and extra devices have mismatched types. This improper handling of device initialization error...

EUVD-2026-6122

A security flaw has been discovered in Flos Freeware Notepad2 4.2.22/4.2.23/4.2.24/4.2.25. Affected is an unknown function in the library Msimg32.dll. Performing a manipulation results in uncontrolled search path. Attacking locally is a requirement. The attack's complexity is rated as high. The...

CVE-2026-23856

Dell iDRAC Service Module iSM for Windows, versions prior to 6.0.3.1, and Dell iDRAC Service Module iSM for Linux, versions prior to 5.4.1.1, contain an Improper Access Control vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to...

UBUNTU-CVE-2026-0965

A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service DoS by causing the system t...

Fortinet FortiClient Improper Link Resolution Before File Access (FG-IR-25-661)
