CVSS: 6.7EPSS: 0%CPEs: 8EXPL: 0CVE-2023-28772 – kernel: lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow
https://notcve.org/view.php?id=CVE-2023-28772
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://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.3 https://github.com/torvalds/linux/commit/d3b16034a24a112bb83aeb669ac5b9b01f744bb7 https://lkml.kernel.org/r/20210626032156.47889-1-yun.zhou%40windriver.com https://lore.kernel.org/lkml/20210625122453.5e2fe304%40oasis.local.home https://security.netapp.com/advisory/ntap-20230427-0005 https://access.redhat.com/security/cve/CVE-2023-28772 https://bugzilla.redhat.com/show_bug.cgi?id=2181330 • 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') •

CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 0CVE-2023-1390 – kernel: remote DoS in TIPC kernel module
https://notcve.org/view.php?id=CVE-2023-1390
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 https://github.com/torvalds/linux/commit/b77413446408fdd256599daf00d5be72b5f3e7c6 https://infosec.exchange/%40_mattata/109427999461122360 https://security.netapp.com/advisory/ntap-20230420-0001 https://access.redhat.com/security/cve/CVE-2023-1390 https://bugzilla.redhat.com/show_bug.cgi?id=2178212 • CWE-1050: Excessive Platform Resource Consumption within a Loop •
