Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the use of mutex locks in an atomic context that could lead to sleep...

PT-2025-30788

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contained an issue where a mutex was used to protect the notifier hashtable accesses, potentially leading to sleeping within an atomic context. This resulted in kernel...

SUSE CVE-2025-38349

In the Linux kernel, the following vulnerability has been resolved: eventpoll: don't decrement ep refcount while still holding the ep mutex Jann Horn points out that epoll is decrementing the ep refcount and then doing a mutexunlock&ep-mtx; afterwards. That's very wrong, because it can lead to a...

CVE-2025-38349

The CVE-2025-38349 entry concerns a Linux kernel eventpoll use-after-free risk due to dropping the epoll refcount while the ep mutex is still held. Description and related details explain that incrementing/decrementing the ep refcount in the wrong order combined with unlock timing can allow a con...
