Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from three control scenarios in the ov5647 driver’s sctrl function that directly return without callin...

CVE-2026-45978

A flaw was found in the Linux kernel's Greybus Lights subsystem. This vulnerability occurs when the gblightslightconfig function attempts to store a channel count before successfully allocating the corresponding channels array. If the memory allocation fails, a subsequent cleanup operation can tr...

CVE-2026-46040

A flaw was found in the Linux kernel's inotify subsystem. When the fsnotifyaddinodemarklocked function fails during the creation of a new watch, the system does not properly decrement the watch count. This oversight can lead to a watch count leak, where repeated failures exhaust the maximum user...

CVE-2026-46048

A flaw was found in the Linux kernel's ALSA caiaq driver. This vulnerability, a reference count leak, occurs when the createcard function acquires a reference to a USB device, but the corresponding release is not performed if initcard fails before the destructor is properly assigned. A local...

EUVD-2026-32381

In the Linux kernel, the following vulnerability has been resolved: fat: avoid parent link count underflow in rmdir Corrupted FAT images can leave a directory inode with an incorrect inlink e.g. 2 even though subdirectories exist. rmdir then unconditionally calls dropnlinkdir and can drive inlink...
