A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. A call to btsdio_remove with an unfinished job may cause a race problem which leads to a UAF on hdev devices.
It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for thisCVE, kernel support for the TCINDEX classifier has been removed. William Zhao discovered that the Traffic Control subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service.
