The Linux Kernel, the operating system core itself.
Security Fix(es):
An issue was discovered in the Linux kernel before 6.6.8. rose_ioctl in net/rose/af_rose.c has a use-after-free because of a rose_accept race condition.(CVE-2023-51782)
A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of service (DoS) attack due to a refcount overflow.(CVE-2023-7192)
