kernel: Linux kernel use-after-free in eventpoll

A flaw was found in the Linux kernel's eventpoll epoll mechanism. A local attacker could exploit a use-after-free vulnerability due to incorrect handling of the 'ep' refcount while the 'ep' mutex is still held. This can lead to memory corruption, potentially allowing the attacker to achieve...

CVE-2025-71204

A reference count leak flaw was found in the Linux kernel's ksmbd in-kernel SMB server. In the parsedurablehandlecontext function, when a command is detected as a replay operation and returns -ENOEXEC, the reference count of the ksmbdfile structure is not properly released. This leads to a resour...
