CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 0CVE-2023-3609 – Use-after-free in Linux kernel's net/sched: cls_u32 component
https://notcve.org/view.php?id=CVE-2023-3609
A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc. A double-free flaw was found in u32_set_parms in net/sched/cls_u32.c in the Network Scheduler component in the Linux kernel. This flaw allows a local attacker to use a failure event to mishandle the reference counter, leading to a local privilege escalation threat. • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=04c55383fa5689357bcdd2c8036725a55ed632bc https://kernel.dance/04c55383fa5689357bcdd2c8036725a55ed632bc https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.neta • CWE-415: Double Free CWE-416: Use After Free •

CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-38409 – kernel: fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment
https://notcve.org/view.php?id=CVE-2023-38409
An issue was discovered in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Linux kernel before 6.2.12. Because an assignment occurs only for the first vc, the fbcon_registered_fb and fbcon_display arrays can be desynchronized in fbcon_mode_deleted (the con2fb_map points at the old fb_info). A memory corruption flaw was found in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Framebuffer Console in the Linux kernel. This flaw allows a local attacker to crash the system, leading to a denial of service. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.12 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=fffb0b52d5258554c645c966c6cbef7de50b851d https://access.redhat.com/security/cve/CVE-2023-38409 https://bugzilla.redhat.com/show_bug.cgi?id=2230042 • CWE-129: Improper Validation of Array Index CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds and crash in read_descriptors in drivers/usb/core/sysfs.c. An out-of-bounds read issue was found in the USB subsystem in the Linux kernel.
