kernel: ixgbe: Fix panic during XDP_TX with > 64 CPUs

A flaw was found in the Linux kernel's ixgbe network driver. On systems with more than 64 CPUs, XDPTX operations can cause a kernel panic due to an array-index-out-of-bounds access. The ixgbexdplockingkey variable can be incorrectly decremented to zero during ring reconfiguration, causing the...

kernel: dm: fix a race condition in retrieve_deps

A use-after-free flaw was found in the Linux kernel's device-mapper multipath implementation. A race condition exists between retrievedeps and multipathmessage when devices are added or removed. The retrievedeps function walks the device list without holding a lock while multipathmessage can modi...
