CVE-2026-81008

A flaw was found in the Linux kernel's interconnect subsystem. When a dynamic memory allocation fails during path initialization, an object is prematurely freed while still being referenced in internal lists. This creates dangling pointers, which can be later accessed or modified. This...

CVE-2026-80999

A flaw was found in the Linux kernel's Realtek Digital Subscriber Line DSA driver. The driver incorrectly uses gpiodsetvalue instead of gpiodsetvaluecansleep for reset GPIO operations. This can lead to system warnings when the reset GPIO is managed by a sleeping controller, potentially causing...

CVE-2026-80989

A flaw was found in the Linux kernel's Thunderbolt networking subsystem. When a Thunderbolt connection fails to establish, the system may not correctly update its state, leading to repeated attempts to tear down an already inactive connection. This can result in a kernel warning and, under certai...

CVE-2026-89703

A flaw was found in the nfsd component of the Linux kernel. The nfsd4droprevokedstid function, which handles admin-revoked delegations, fails to correctly set a status flag before releasing a lock. This oversight can lead to a use-after-free condition when a freed delegation is incorrectly added ...

CVE-2026-89702

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When processing NFSv2/v3-over-UDP requests, the nfsdfhverify and nfsdfhverifyerr tracepoints incorrectly size a memory buffer. This can lead to an out-of-bounds write, potentially allowing a remote attacker to cause a denial ...

CVE-2026-89708

A flaw was found in the Linux kernel's NFS daemon nfsd. During the teardown of an NFSv4 session, a race condition can occur where the session's memory is freed while an active callback task still holds a reference to it. This can lead to a use-after-free vulnerability, potentially causing system...

CVE-2026-89700

A flaw was found in the Linux kernel's nfsd component. A local user with CAPNETADMIN capabilities can exploit this by sending a specially crafted network attribute with an incorrect address family length. This can lead to an out-of-bounds read, potentially disclosing sensitive information or...

실행 공간 보호 우회 CVE-2022-25265 이 POC는 바이너리의 실행 불가 영역으로 간주되는 곳에 위치한 바이트를 실행하여 실행 공간 보호를 완전히 우회하는 것을 시연합니다. 이에 대한 근본 원인은 여기에서 확인할 수 있습니다. https://github.com/torvalds/linux/blob/master/arch/x86/include/asm/elf.hL280 개요 알고 보면, NX가 없는 시스템 또는 NX가 있는 IA32 시스템에서 빌드되었지만 PTGNUSTACK 헤더를 포함하지 않는 바이너리 파일은 exec-al...

CVE-2026-89548

A flaw was found in the Linux kernel's SUNRPC component. When sunrpcdestroycachedetail is called, it may not properly drain the cachecleaner before freeing a cachedetail object. This oversight can lead to a use-after-free vulnerability, where the system attempts to access or use memory that has...

CVE-2026-81018

A flaw was found in the Linux kernel's think-lmi driver. When the driver is removed, the system authentication object fails to free stored certificate signatures, leading to a memory leak. This can result in system instability or denial of service over time due to resource exhaustion...

CVE-2026-89715

A flaw was found in the Linux kernel's NFS/localio component. A race condition during file handling can lead to a reference leak, where system resources are not properly released. This continuous accumulation of unreleased references can exhaust available resources, preventing network namespace...

CVE-2026-89707

A flaw was found in the Linux kernel's nfsd component. An authenticated Network File System NFS client can exploit this vulnerability by triggering a failed cross-mount operation through nfsdlookupdentry or the NFSv4 READDIR encode path. This leads to a reference count leak, which inflates mntcou...

CVE-2026-89491

A flaw was found in the Linux kernel's ocfs2 cluster module. This vulnerability allows a local attacker to trigger a denial of service. The issue arises when a sleeping function is called while a spinlock is held within the o2hbregionpin function, which can lead to a system crash or deadlock. Thi...

CVE-2026-89588

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI APEI Generic Hardware Error Source GHES component. Incorrect length accounting in the gheshandlearmhwerror function can lead to the parser reading beyond the allocated memory section. This out-of-bounds read...

CVE-2026-89767

A flaw was found in the Linux kernel's overlay file system overlayfs. An unprivileged local user can trigger a specific error condition during the creation of a new directory. This error causes the system to incorrectly release a lock on the parent directory and a reference to the new directory...

CVE-2026-89762

A flaw was found in the Linux kernel's AppArmor security module. The begincurrentlabelcritsection function, used in various Linux Security Module LSM hooks, attempts to replace user credentials when a security label becomes stale. This process can lead to a Use-After-Free UAF vulnerability if the...

CVE-2026-89740

A flaw was found in the Linux kernel's serial: imx component. The imxuartprobe function publishes a device-managed allocated port in the imxuartports array before it is fully added. If the port addition fails or the port is removed, the entry in the array is not properly cleared, resulting in a...

CVE-2026-89724

A flaw was found in the Linux kernel's media: vicodec component. An out-of-bounds write vulnerability exists in the FWHT encoder due to incorrect buffer sizing during video output format handling. This issue allows an attacker to cause corruption of adjacent kernel heap memory, which could lead t...

CVE-2026-89632

A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server could exploit this vulnerability by sending specially crafted data, leading to an out-of-bounds read. This occurs because the reparsebufptr function reads data before properly validating the buffer size,...

CVE-2026-89621

A flaw was found in the Linux kernel's HID Human Interface Device mcp2221 driver. A malicious USB device can exploit this vulnerability by sending a specially crafted, short HID report with an invalid size. This can cause the system to read past valid memory, leading to the disclosure of sensitiv...
