CVE-2026-45763

A flaw was found in Suricata. When Lua rule execution is enabled, a remote attacker could exploit certain Lua allocation patterns to bypass the intended memory limits. This could lead to the Suricata engine consuming excessive memory, resulting in a Denial of Service DoS condition...

CVE-2026-89699

A flaw was found in the Linux kernel's Network File System Daemon nfsd when handling NFSv4 CREATE operations. A remote attacker can exploit this by sending a crafted request with an oversized symbolic link symlink target length. This unbounded length can force the kernel to allocate a large amoun...

CVE-2026-89763

A flaw was found in the Linux kernel's Trusted Platform Module TPM trusted keys subsystem. An incorrect teardown ordering during the exit process of trusted TPM keys can lead to a race condition. This allows a local attacker to potentially dereference a freed memory region, resulting in a...

CVE-2026-89719

A flaw was found in the Linux kernel's zram module. This vulnerability occurs when the readblockstate function calculates the number of pages before acquiring a device lock. If the zram device is reset and reinitialized with a smaller disk size, the function can attempt to access memory beyond th...

CVE-2026-89611

A flaw was found in the Linux kernel. The NTFS file system driver does not properly validate non-resident attribute offsets when converting between sparse and non-sparse attributes. A local attacker could craft a malicious Master File Table MFT record, which could lead to writing data beyond...

CVE-2026-89592

A flaw was found in the accel/rocket component of the Linux kernel. This vulnerability arises from two issues: a missing null check after a memory allocation failure and an integer overflow when calculating memory requirements based on user-supplied values. An attacker could exploit these flaws t...

CVE-2026-89546

A flaw was found in the Linux kernel's SUNRPC Sun Remote Procedure Call Network File System NFS callback service. A race condition during the service teardown can lead to system resources not being properly released, causing a resource leak. This issue could also result in a use-after-free...

CVE-2026-89521

A flaw was found in the Linux kernel's core scheduling component. This issue occurs when the picktask function releases the run queue rq lock, allowing an interleaving selection to invalidate the scheduler's internal state. This inconsistency can lead to incorrect task selection and skewed resour...

CVE-2026-80996

A flaw was found in the Linux kernel's L2TP Layer 2 Tunneling Protocol networking component. Specifically, the netlink handlers responsible for creating and modifying L2TP tunnels and sessions may fail to propagate multicast notification errors. This can lead to calling applications retrying...

CVE-2026-80944

A flaw was found in the Linux kernel's mwifiex Wi-Fi driver. When a synchronous command's wait operation is interrupted, the driver can attempt to write data to a memory location that has already been released. This memory corruption can lead to a system crash kernel panic, resulting in a Denial ...

CVE-2026-80934

A flaw was found in the Linux kernel's mt76: mt7996 Wi-Fi driver. The driver incorrectly manages Direct Memory Access DMA mappings when processing AddBA request frames, causing a continuous leak of these mappings. Over time, this resource exhaustion can lead to a Denial of Service DoS for the Wi-...

CVE-2019-1476

CVE-2019-1476 AppXSvc 任意文件覆盖 DoS 我独立地将此漏洞报告给了 MSRC，这是我受 CVE-2019-0841 启发所开展研究的一部分，该漏洞最初由 Nabeel Ahmed 报告。该漏洞允许普通用户覆盖任意文件。然而，由于攻击者无法控制文件内容，其能力受到限制，因此它最可能被用于各种拒绝服务场景。更多信息请参阅 AppXSvc 中的任意文件覆盖。...

CVE-2026-89756

A flaw was found in the Linux kernel. When performing memory migration on KVM Kernel-based Virtual Machine hosts, the migratepagesbatch function fails to report RCU Read-Copy Update tasks quiescent states during large batch unmapping operations. This oversight causes the migrating task to become ...

CVE-2026-89742

A flaw was found in the Linux kernel. A local user could exploit a use-after-free vulnerability in the dmareqfree function within the RapidIO mport character device interface. This flaw occurs when the dmareqfree function attempts to dereference a freed object after dropping the last reference to...

CVE-2026-89771

A flaw was found in the Linux kernel. A race condition exists in the ring buffer resizing mechanism, where tracebuffer subbufsize can be read without proper locking while it is being simultaneously resized. This could allow a local attacker to trigger unpredictable behavior or a denial of service...

CVE-2026-89753

A flaw was found in the Linux kernel's memory management subsystem. The shrinklruvec function, responsible for memory reclaim, fails to properly report Read-Copy-Update RCU task quiescent states on systems with preemption enabled. This can lead to RCU task stalls, causing system unresponsiveness ...

CVE-2026-89720

A flaw was found in the Linux kernel's Unsorted Block Image File System UBIFS. An incorrect bounds check in the ubifssbverifysignature function allows a crafted signed UBIFS image to declare a signature length larger than its actual size. This can lead to an out-of-bounds read when processing the...

CVE-2026-89710

A flaw was found in the Linux kernel's NFSv4.1 implementation. When a server returns a new layout state identifier while an existing one is still active, the pnfslayoutprocess function fails to properly release memory associated with layout segments. This oversight leads to a memory leak, which...

CVE-2026-89623

A flaw was found in the Linux kernel's HID Human Interface Device mcp2221 driver. This vulnerability occurs when the device's input/output IO operations are not properly stopped before hardware teardown during device removal or probe failure. This timing issue can lead to a use-after-free...

CVE-2026-89612

A flaw was found in the Linux kernel's NTFS filesystem driver. A local attacker could provide a specially crafted NTFS boot sector containing an invalid Master File Table MFT Logical Cluster Number LCN. Due to an integer overflow during parsing, this could lead to an out-of-bounds memory access...
