CVE-2026-80653

A flaw was found in the Linux kernel's hisisas driver. A local attacker or privileged user could trigger a kernel warning by simultaneously performing a link reset on a remote physical layer PHY device and removing the SAS driver. This race condition can lead to system instability or a denial of...

CVE_2026_40369

CVE202640369 Exploit poc and exp for CVE202640369, related to my analyze, use cmake. Debug code, poc and exp files for reproducing CVE202640369, written with cmake. As before, you can compile it directly using the regular cmake commands. About the analysis article: WeChat Official Account:...

CVE-2026-80712

A flaw was found in the Linux kernel's spi-qpic-snand driver. This vulnerability arises from an incorrect timing issue where the SETFEATURE command for SPI-NAND flash devices is executed before the intended feature value is properly written. Consequently, the device is programmed with an outdated...

CVE-2026-80619

A flaw was found in the AppArmor security module of the Linux kernel. The aareplaceprofiles function was susceptible to a use-after-free UAF vulnerability. This occurred because the function accessed data after it had been deallocated, potentially allowing an attacker to cause a denial of service...

CVE-2026-80670

A flaw was found in the Linux kernel's perf tools. The machineresolve function, responsible for resolving machine addresses, does not properly validate CPU index values from untrusted perf.data samples. A local attacker could provide a specially crafted perf.data file with a large CPU index,...

CVE-2026-80654

A flaw was found in the Linux kernel. An incorrect condition check during the cleanup of a mailbox receive channel in the soc: xilinx component allows the channel to remain active and receive messages even after the device has been removed. This oversight leads to a use-after-free vulnerability,...

CVE-2026-80639

A flaw was found in the Linux kernel's cxl/test module. A buffer overflow vulnerability, a type of memory corruption, exists within the setupxormapping function. This flaw could allow a local user to trigger a runtime assertion failure, potentially leading to system instability or a denial of...

CVE-2026-80604

A flaw was found in the Linux kernel's Human Interface Device HID core. When processing numbered reports, the hidgetreport function can attempt to read data from an invalid memory location if a size of zero is provided. This out-of-bounds read can lead to a kernel panic, effectively causing a...

CVE-2026-80595

A flaw was found in the Linux kernel. The ims-pcu driver processes response data from device buffers without verifying the actual length of the data sent by the device. This oversight can lead to out-of-bounds reads, potentially allowing an attacker to access sensitive information or cause system...

CVE-2026-80594

A flaw was found in the Linux kernel's ims-pcu driver. This vulnerability allows a malicious device to trigger an infinite loop by providing a specially crafted descriptor with a zero-length field during the parsing of CDC union descriptors. This can lead to a Denial of Service DoS condition,...

CVE-2026-80592

A flaw was found in the Linux kernel. A local user could trigger a kernel warning by enabling the mtier sample module before its address range parameters are properly initialized. This issue, caused by invalid address range parameters, could lead to system instability or a denial of service...

CVE-2026-80693

A flaw was found in the Linux kernel's idpf component. A privileged control plane such as a Physical Function or a hypervisor device model could exploit a vulnerability by providing a malformed reply to an interrupt-vector allocation request. This malformed reply, where the sum of per-chunk vecto...

CVE-2026-80648

A flaw was found in the pinctrl pin controller driver for SpacemiT systems in the Linux kernel. An incorrect NULL check in the spacemitpinsetconfig function can lead to a NULL pointer dereference. This occurs when the system attempts to configure a pin that is not present in the SoC's pin table,...

CVE-2026-80636

A flaw was found in the Netfilter conntrack component of the Linux kernel. This vulnerability arises from the improper handling of connection tracking conntrack extensions. Specifically, a codebase change that disables all conntrack extensions for unconfirmed conntracks, without proper null check...

CVE-2026-80628

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer OSS Open Sound System emulation. A local user could exploit a data race condition when the sndseqossreadqclear function resets the read queue state without proper locking. This can lead to stale records, dropp...

CVE-2026-80682

A flaw was found in the Linux kernel's RISC-V memory management component. An incorrect calculation for memory alignment during system initialization could lead to a kernel warning. This issue arises when the physical memory base address is not properly aligned, potentially causing system...

CVE-2026-80678

A flaw was found in the Linux kernel's i2c: imx driver. A race condition during I2C slave registration and error handling could lead to a NULL pointer dereference. This occurs when the i2cimx-slave pointer is not properly cleared or assigned, especially if power management operations fail or if t...

CVE-2026-80725

A flaw was found in the Linux kernel’s Generic Receive Offload GRO component, which handles network packet aggregation. Improper validation of BIG TCP aggregation criteria allows a remote attacker to send specially crafted network frames. This can lead to an out-of-bounds write when processing IP...

CVE-2026-80633

A flaw was found in the Linux kernel's iommufd component. A local user could trigger a kernel warning by releasing the last reference on a Direct Memory Access Buffer DMABUF-backed IOMMU page table without holding the necessary dmaresv lock. This missing lock operation can lead to system...
