UBUNTU-CVE-2022-48914

In the Linux kernel, the following vulnerability has been resolved: xen/netfront: destroy queues before realnumtxqueues is zeroed xennetdestroyqueues relies on info-netdev-realnumtxqueues to delete queues. Since d7dac083414eb5bb99a6d2ed53dc2c1b405224e5 "net-sysfs: update the queue counts in the...

CVE-2022-48914

CVE-2022-48914 affects the Linux kernel’s xen_netfront/xennet_destroy_queues path. The vulnerability arises because xennet_destroy_queues() relies on netdev->real_num_tx_queues, which is cleared after unregister_netdev() due to net-sysfs changes, causing a NULL dereference when freeing queues ...

CVE-2022-48871

In CVE-2022-48871, the Linux kernel fix targets tty: serial: qcom-geni-serial slab-out-of-bounds on the RX FIFO buffer. The probe allocates port->rx_fifo using a default depth (e.g., 16); during serial startup, port->rx_fifo_depth is updated to match device capabilities (e.g., 32). The RX U...

UBUNTU-CVE-2024-43872

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix soft lockup under heavy CEQE load CEQEs are handled in interrupt handler currently. This may cause the CPU core staying in interrupt context too long and lead to soft lockup under heavy load. Handle CEQEs in BH...

kernel: ice: fix memory corruption bug with suspend and rebuild

This is a flaw in the Linux kernel's ICE driver for Intel Ethernet controllers. The problem arises when the system enters a suspended state, and the driver frees queue vectors without resetting the numqvectors variable. This oversight causes the icerebuild function to allocate an incorrectly size...

kernel: netfilter: nf_tables: flush pending destroy work before exit_net release

A vulnerability was found in the Linux kernel's Netfilter framework, specifically within the nftables component. The issue arises from a race condition between the exitnet function and the destroy work queue, which can lead to use-after-free errors and potential system instability. This...
