USN-5443-2: Linux kernel vulnerabilities

Read Time:25 Second

Kyle Zeng discovered that the Network Queuing and Scheduling subsystem of
the Linux kernel did not properly perform reference counting in some
situations, leading to a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or execute
arbitrary code. (CVE-2022-29581)

Jann Horn discovered that the Linux kernel did not properly enforce seccomp
restrictions in some situations. A local attacker could use this to bypass
intended seccomp sandbox restrictions. (CVE-2022-30594)
