CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 0CVE-2023-1281 – UAF in Linux kernel's tcindex (traffic control index filter) implementation
https://notcve.org/view.php?id=CVE-2023-1281
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. A use-after-free vulnerability was found in the traffic control index filter (tcindex) in the Linux kernel. The imperfect hash area can be updated while packets are traversing. • http://www.openwall.com/lists/oss-security/2023/04/11/3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ee059170b1f7e94e55fa6cadee544e176a6e59c2 https://kernel.dance/#ee059170b1f7e94e55fa6cadee544e176a6e59c2 https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://security.netapp.com/advisory/ntap-20230427-0004 https://access.redhat.com/security/cve/CVE-2023-1281 https://bugzilla.r • CWE-416: Use After Free •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-1249 – kernel: missing mmap_lock in file_files_note that could possibly lead to a use after free in the coredump code
https://notcve.org/view.php?id=CVE-2023-1249
A use-after-free flaw was found in the Linux kernel’s core dump subsystem. This flaw allows a local user to crash the system. Only if patch 390031c94211 ("coredump: Use the vma snapshot in fill_files_note") not applied yet, then kernel could be affected. • http://packetstormsecurity.com/files/171912/CentOS-Stream-9-Missing-Kernel-Security-Fix.html https://patchwork.kernel.org/project/linux-fsdevel/patch/87iltzn3nd.fsf_-_%40email.froward.int.ebiederm.org https://access.redhat.com/security/cve/CVE-2023-1249 https://bugzilla.redhat.com/show_bug.cgi?id=2169719 • CWE-416: Use After Free •

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 •
