28 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Fix pte update for kernel memory on radix When adding a PTE a ptesync is needed to order the update of the PTE with subsequent accesses otherwise a spurious fault may be raised. radix__set_pte_at() does not do this for performance gains. For non-kernel memory this is not an issue as any faults of this kind are corrected by the page fault handler. For kernel memory these faults are not handled. The current solution is that there... • https://git.kernel.org/stable/c/f1cb8f9beba8699dd1b4518418191499e53f7b17 •

28 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-clt: destroy sysfs after removing session from active list A session can be removed dynamically by sysfs interface "remove_path" that eventually calls rtrs_clt_remove_path_from_sysfs function. The current rtrs_clt_remove_path_from_sysfs first removes the sysfs interfaces and frees sess->stats object. Second it removes the session from the active list.

28 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: free queued packets when closing socket As reported by syzbot [1], there is a memory leak while closing the socket. We partially solved this issue with commit ac03046ece2b ("vsock/virtio: free packets during the socket release"), but we forgot to drain the RX queue when the socket is definitely closed by the scheduled work.

In bnxt_rx_pkt(), the RX buffers are expected to complete in order. If the RX consumer index indicates an out of order buffer completion, it means we are hitting a hardware bug and the driver will abort all remaining RX packets and reset the RX ring.
