CVE-2023-0266 – Linux Kernel Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2023-0266
A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel. SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit 56b88b50565cd8b946a2d00b0c83927b7ebb055e A use-after-free flaw was found in snd_ctl_elem_read in sound/core/control.c in Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. In this flaw a normal privileged, local attacker may impact the system due to a locking issue in the compat path, leading to a kernel information leak problem. Linux kernel contains a use-after-free vulnerability that allows for privilege escalation to gain ring0 access from the system user. • https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tree/queue-5.10/alsa-pcm-move-rwsem-lock-inside-snd_ctl_elem_read-to-prevent-uaf.patch?id=72783cf35e6c55bca84c4bb7b776c58152856fd4 https://github.com/torvalds/linux/commit/56b88b50565cd8b946a2d00b0c83927b7ebb055e https://github.com/torvalds/linux/commit/becf9e5d553c2389d857a3c178ce80fdb34a02e1 https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://access.redhat.com/security/cve/CVE-2023-0266 https://bugzilla.redhat.com/show_bug • CWE-416: Use After Free •

CVE-2023-0122
https://notcve.org/view.php?id=CVE-2023-0122
A NULL pointer dereference vulnerability in the Linux kernel NVMe functionality, in nvmet_setup_auth(), allows an attacker to perform a Pre-Auth Denial of Service (DoS) attack on a remote machine. Affected versions v6.0-rc1 to v6.0-rc3, fixed in v6.0-rc4. • http://www.openwall.com/lists/oss-security/2023/01/18/1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=da0342a3aa0357795224e6283df86444e1117168 https://security.netapp.com/advisory/ntap-20230302-0002 • CWE-476: NULL Pointer Dereference •
CVE-2022-47929 – kernel: NULL pointer dereference in traffic control subsystem
https://notcve.org/view.php?id=CVE-2022-47929
In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c. A NULL pointer dereference flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux kernel. This issue may allow a local unprivileged user to trigger a denial of service if the alloc_workqueue function return is not validated in time of failure, resulting in a system crash or leaked internal kernel information. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.6 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=96398560f26aa07e8f2969d73c8197e6a6d10407 https://lists.debian.org/debian-lts-announce/2023/03/msg00000.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://tldp.org/HOWTO/Traffic-Control-HOWTO/components.html https://www.debian.org/security/2023/dsa-5324 https://www.spinics.net/lists/netdev/msg555705.html https:// • CWE-476: NULL Pointer Dereference •
