24 Mar 2023 — A use-after-free flaw was found in reconn_set_ipaddr_from_hostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server->hostname to NULL, leading to an invalid pointer request. • https://github.com/torvalds/linux/commit/153695d36ead0ccc4d0256953c751cabf673e621 • CWE-416: Use After Free •

23 Mar 2023 — An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow. A buffer overflow write flaw was identified in seq_buf_putmem_hex in lib/seq_buf.c in seq_buf in the Linux Kernel. This issue may allow a user with special debug privileges such as ftrace or root to cause an overflow in the destination buffer due to a missing sanity check. • https://github.com/Trinadh465/linux-4.1.15_CVE-2023-28772 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2023-1281
22 Mar 2023 — Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2.

16 Mar 2023 — A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition. • https://gist.github.com/netspooky/bee2d07022f6350bb88eaa48e571d9b5 • CWE-1050: Excessive Platform Resource Consumption within a Loop •
