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, which originates in the USB module, where the dummy-hcd driver uses hrtimers instead of regular timers, resulting in a task...

CVE-2024-49953 net/mlx5e: Fix crash caused by calling __xfrm_state_delete() twice

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix crash caused by calling xfrmstatedelete twice The km.state is not checked in driver's delayed work. When xfrmstatecheckexpire is called, the state can be reset to XFRMSTATEEXPIRED, even if it is XFRMSTATEDEAD...

CVE-2024-46784

The CVE-2024-46784 issue affects the Linux kernel net: mana subsystem (mana_create_txq/rxq) where napi_disable() is called during cleanup before napi is enabled and hrtimer is initialized, leading to a kernel panic. The Astra Linux bulletin and related advisories confirm a resolved patch in the L...

CVE-2024-42239

CVE-2024-42239 affects the Linux kernel BPF timer cancellation path. The fix adds an atomic counter (cancelling) in bpf_hrtimer to track in-flight cancellation requests and prevents deadlocks when two callbacks attempt to cancel each other in parallel. The patch ensures that if a cancellation is ...
