https://notcve.org/view.php?id=CVE-2022-3623
A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function follow_page_pte of the file mm/gup.c of the component BPF. The manipulation leads to race condition. The attack can be launched remotely. • https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/commit/?id=fac35ba763ed07ba93154c95ffc0c4a55023707f https://lists.debian.org/debian-lts-announce/2023/03/msg00000.html https://vuldb.com/?id.211921 https://www.debian.org/security/2023/dsa-5324 https://access.redhat.com/security/cve/CVE-2022-3623 https://bugzilla.redhat.com/show_bug.cgi?id=2165721 • CWE-123: Write-what-where Condition CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2022-3577
An out-of-bounds memory write flaw was found in the Linux kernel’s Kid-friendly Wired Controller driver. This flaw allows a local user to crash or potentially escalate their privileges on the system. It is in bigben_probe of drivers/hid/hid-bigbenff.c. The reason is incorrect assumption - bigben devices all have inputs. However, malicious devices can break this assumption, leaking to out-of-bound write. • https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/commit/?h=char-misc-next&id=9d64d2405f7d30d49818f6682acd0392348f0fdb https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=945a9a8e448b65bec055d37eba58f711b39f66f0 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fc4ef9d5724973193bfa5ebed181dba6de3a56db • CWE-401: Missing Release of Memory after Effective Lifetime CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2022-3586
A flaw was found in the Linux kernel’s networking code. A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of service. Se ha encontrado un fallo en el código de red del kernel de Linux. Ha sido encontrado un uso de memoria previamente liberada en la forma en que la función sch_sfb enqueue usó el campo cb del búfer de socket (SKB) después de que el mismo SKB había sido puesto en cola (y liberado) en un qdisc hijo. • https://github.com/torvalds/linux/commit/9efd23297cca https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://www.zerodayinitiative.com/advisories/upcoming • CWE-416: Use After Free •
CVSS: 8.8EPSS: 0%CPEs: 5EXPL: 3CVE-2022-2602 – Linux Kernel io_uring Improper Update of Reference Count Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2602
io_uring UAF, Unix SCM garbage collection io_uring UAF, recolección de basura Unix SCM This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the io_uring API. The issue results from the improper management of a reference count. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Linux suffers from an io_uring use-after-free vulnerability due to broken unix GC interaction. • https://github.com/LukeGix/CVE-2022-2602 https://github.com/kiks7/CVE-2022-2602-Kernel-Exploit https://github.com/th3-5had0w/CVE-2022-2602-Study http://packetstormsecurity.com/files/176533/Linux-Broken-Unix-GC-Interaction-Use-After-Free.html https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2602 https://ubuntu.com/security/notices/USN-5691-1 https://ubuntu.com/security/notices/USN-5692-1 https://ubuntu.com/security/notices/USN-5693-1 https://ubuntu.com/security/ • CWE-416: Use After Free •
