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 (kernel memory). (CVE-2023-0458)
It was discovered that a use-after-free vulnerability existed in the IEEE 1394 (Firewire) implementation in the Linux kernel. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3159)
It was discovered that the virtual terminal driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2023-3567)
It was discovered that the Quick Fair Queueing network scheduler implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3611)
It was discovered that the network packet classifier with netfilter/firewall marks implementation in the Linux kernel did not properly handle reference counting, 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-2023-3776)
