UBUNTU-CVE-2024-42127

In the Linux kernel, the following vulnerability has been resolved: drm/lima: fix shared irq handling on driver remove lima uses a shared interrupt, so the interrupt handlers must be prepared to be called at any time. At driver removal time, the clocks are disabled early and the interrupts stay...

UBUNTU-CVE-2024-42230

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fix scv instruction crash with kexec kexec on pseries disables AIL reloconexc, required for scv instruction support, before other CPUs have been shut down. This means they can execute scv instructions after AIL i...

CVE-2024-42230

In CVE-2024-42230, the Linux kernel on pseries PowerPC is affected by a scv instruction crash when kexec is used. The root cause is that kexec on pseries disables AIL (reloc_on_exc), required for scv instruction support, before all CPUs have been shut down, allowing scv instructions to execute af...

CVE-2024-42112 net: txgbe: free isb resources at the right time

In the Linux kernel, the following vulnerability has been resolved: net: txgbe: free isb resources at the right time When using MSI/INTx interrupt, the shared interrupts are still being handled in the device remove routine, before free IRQs. So isb memory is still read after it is freed. Thus mov...

CVE-2024-42110 net: ntb_netdev: Move ntb_netdev_rx_handler() to call netif_rx() from __netif_rx()

In the Linux kernel, the following vulnerability has been resolved: net: ntbnetdev: Move ntbnetdevrxhandler to call netifrx from netifrx The following is emitted when using idxd DSA dmanegine as the data mover for ntbtransport that ntbnetdev uses. 74412.546922 BUG: using smpprocessorid in...

CVE-2024-42110 net: ntb_netdev: Move ntb_netdev_rx_handler() to call netif_rx() from __netif_rx()

CVE-2024-42110

CVE-2024-42110 affects the Linux kernel ntb_netdev/ntb_transport path. The root cause is that the idxd DMA engine can complete TX/RX in a threaded IRQ context, but __netif_rx() is only safe from interrupt context. The code previously called __netif_rx() from a completion path and should instead u...
