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 •
CVSS: 7.0EPSS: 0%CPEs: 11EXPL: 0CVE-2023-28466 – kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference
https://notcve.org/view.php?id=CVE-2023-28466
do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference). A use-after-free flaw was found in the do_tls_getsockopt function in net/tls/tls_main.c in the Transport Layer Security (TLS) in the Network subcompact in the Linux kernel. This flaw allows an attacker to cause a NULL pointer dereference problem due to a race condition. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=49c47cc21b5b7a3d8deb18fc57b0aa2ab1286962 https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://security.netapp.com/advisory/ntap-20230427-0006 https://access.redhat.com/security/cve/CVE-2023-28466 https://bugzilla.redhat.com/show_bug.cgi?id=2179000 • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •
