The Linux Kernel, the operating system core itself.
Security Fix(es):
A flaw was found in the Bluetooth subsystem of the Linux kernel. A race condition between the btsockrecvmsg() and btsockioctl() functions could lead to a use-after-free on a socket buffer ("skb"). This flaw allows a local user to cause a denial of service condition or potential code execution.(CVE-2023-51779)
An issue was discovered in the Linux kernel before 6.6.8. dovccioctl in net/atm/ioctl.c has a use-after-free because of a vcc_recvmsg race condition.(CVE-2023-51780)
An issue was discovered in the Linux kernel before 6.6.8. atalkioctl in net/appletalk/ddp.c has a use-after-free because of an atalkrecvmsg race condition.(CVE-2023-51781)
An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).(CVE-2023-6121)
