24 Jul 2023 — A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information. • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html • CWE-416: Use After Free •

24 Jul 2023 — 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 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2023-3776 – Use-after-free in Linux kernel's net/sched: cls_fw component
https://notcve.org/view.php?id=CVE-2023-3776
21 Jul 2023 — A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_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 0323bce598eea038714f941ce2b225... • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-3611
21 Jul 2023 — An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. An out-of-bounds memory write flaw was found in qfq_change_agg in net/sched/sch_qfq.c in the Traffic Control (QoS) subsystem in the Lin... • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3e337087c3b5805fe0b8a46ba622a962880b5d64 • CWE-787: Out-of-bounds Write •

17 Jul 2023 — 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.
