An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This flaw allows a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data to be printed to the kernel ring buffer . A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group.We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation.A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread.We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1
