Descriptions
A use after free issue was discovered in driver/firewire in outbound_phy_packet_callback in the Linux Kernel. In this flaw a local attacker with special privilege may cause a use after free problem when queue_event() fails.
Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the do_prlimit function in the Linux kernel did not properly handle speculative execution barriers. A local attacker could use this to expose sensitive information. It was discovered that a race condition existed in the btrfs file system implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly expose sensitive information.
