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 the xfs inodeitempush and xfsqmdquotlogitempush functions. These functions access lip-liailp afte...

PT-2026-34358

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the XFS file system where log items may be dereferenced after push callbacks. Specifically, after the xfsaild push item function calls iop push, the log item might hav...
