a303779215387d2d07fb407deb0825590a084fec90228cb48f5b751101f72a26Ubuntu Security Notice 5913-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Lee Jones discovered that a use-after-free vulnerability existed in the Bluetooth implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
a4ae9d6a9647addb9e05bc1aa69a3349777b844421602b87d15394ae0ac3f4d8Ubuntu Security Notice 5774-1 - Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service.

A local attacker could use this to expose sensitive information. It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
7aaa31ceef76ec8bdfbe0b205ddec2f0fbf8452e3b09e76f3ff397adbff1ccefUbuntu Security Notice 5703-1 - Selim Enes Karaduman discovered that a race condition existed in the General notification queue implementation of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with Enhanced Indirect Branch Restricted Speculation did not properly handle RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive information.
