UBUNTU-CVE-2025-40305

In the Linux kernel, the following vulnerability has been resolved: 9p/transfd: p9fdrequest: kick rx thread if EPOLLIN p9readwork doesn't set Rworksched and doesn't do scheduleworkm-rq if listempty&m-reqlist. However, if the pipe is full, we need to read more data and this used to work prior to...

CVE-2025-40305

CVE-2025-40305 concerns Linux kernel 9p/trans_fd handling. Root cause: p9_fd_request relied on EPOLLOUT checks and wakeups via p9_pollwake/p9_poll_mux; after a pipe-read optimization, unnecessary wakeups were avoided by changing logic, reducing EPOLLIN-driven scheduling. The fix changes p9_fd_req...
