In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Fix listener leak in rdmacmalistenonall failure If cmalistenonall fails it leaves the per-device ID still on the listenlist but the state is not set to RDMACMADDRBOUND. When the cmid is eventually destroyed...

UBUNTU-CVE-2021-47305

In the Linux kernel, the following vulnerability has been resolved: dma-buf/syncfile: Don't leak fences on merge failure Each addfence call does a dmafenceget on the relevant fence. In the error path, we weren't calling dmafenceput so all those fences got leaked. Also, in the kreallocarray failur...

UBUNTU-CVE-2021-47391

In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Ensure rdmaaddrcancel happens before issuing more requests The FSM can run in a circle allowing rdmaresolveip to be called twice on the same idpriv. While this cannot happen without going through the work, it violates t...

CVE-2021-47301

Summary: CVE-2021-47301 affects the Linux kernel igb/igc driver stack. Root cause: a use-after-free in the reset path where next_to_watch is not cleared while cleaning the TX ring, risking a freed skb being freed again if igb_poll() executes during reset. Impact: potential invalid memory accesses...
