CVE-2024-14027

In the Linux kernel, the following vulnerability has been resolved: fs/xattr: missing fdput in fremovexattr error path In the Linux kernel, the fremovexattr syscall calls fdget to acquire a file reference but returns early without calling fdput when strncpyfromuser fails on the name argument. In...

CVE-2024-14027

In the Linux kernel, CVE-2024-14027 affects the xattr path: fremovexattr() calls fdget() but omits fdput() on failure of strncpy_from_user() for the name argument, leaking a file reference per call in multi-threaded processes and enabling local kernel memory exhaustion by an unprivileged user. Th...

CVE-2024-14027 xattr: switch to CLASS(fd)

In the Linux kernel, the following vulnerability has been resolved: fs/xattr: missing fdput in fremovexattr error path In the Linux kernel, the fremovexattr syscall calls fdget to acquire a file reference but returns early without calling fdput when strncpyfromuser fails on the name argument. In...

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 absence of the fdput call in the fremovexattr error path. This vulnerability could potentiall...

Android - binder Use-After-Free via fdget() Optimization Exploit

Android - binder Use-After-Free via fdget Optimization Exploit This bug report describes two different issues in different branches of the binder kernel code. The first issue is in the upstream Linux kernel, commit 7f3dc0088b98 "binder: fix proc-files use-after-free"; the second issue is in the...

Android - binder Use-After-Free via fdget() Optimization

This bug report describes two different issues in different branches of the binder kernel code. The first issue is in the upstream Linux kernel, commit 7f3dc0088b98 "binder: fix proc-files use-after-free"; the second issue is in the wahoo kernel and maybe elsewhere? but at least the android commo...
