https://notcve.org/view.php?id=CVE-2023-3863
A use-after-free flaw was found in nfc_llcp_find_local in net/nfc/llcp_core.c in NFC in the Linux kernel. This flaw allows a local user with special privileges to impact a kernel information leak issue. • https://access.redhat.com/security/cve/CVE-2023-3863 https://bugzilla.redhat.com/show_bug.cgi?id=2225126 https://github.com/torvalds/linux/commit/6709d4b7bc2e079241fdef15d1160581c5261c10 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://security.netapp.com/advisory/ntap-20240202-0002 https://www.debian.org/security/2023/dsa-5480 https://www.debian.org/security/2023/dsa-5492 • 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') •
