USN-5793-3: Linux kernel vulnerabilities

It was discovered that the iouring subsystem in 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 possibly execute arbitrary code. CVE-2022-3910 ...

kernel: iptables restriction bypass if a protocol handler kernel module not loaded

A flaw was found in the way the Linux kernel's netfilter subsystem handled generic protocol tracking. As demonstrated in the Stream Control Transmission Protocol SCTP case, a remote attacker could use this flaw to bypass intended iptables rule restrictions when the associated connection tracking...
