CVE-2023-1206
A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6...
SUSE CVE-2023-35788
An issue was discovered in flsetgeneveopt in net/sched/clsflower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCAFLOWERKEYENCOPTSGENEVE packets. This may result in denial of service or privilege escalation...
CVE-2023-3220
An issue was discovered in the Linux kernel through 6.1-rc8. dpucrtcatomiccheck in drivers/gpu/drm/msm/disp/dpu1/dpucrtc.c lacks check of the return value of kzalloc and will cause the NULL Pointer Dereference...
The vulnerability of the Windows operating system’s kernel allows a perpetrator to gain unauthorized access to protected information.
The vulnerability of the Windows operating system’s kernel is related to insufficient protection of sensitive data. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information...
The vulnerability of the fbcon_set_font() function in the drivers/video/fbdev/core/fbcon.c file of the Linux kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.
The vulnerability of the fbconsetfont function in the drivers/video/fbdev/core/fbcon.c file of the Linux kernel is related to integer overflow due to the lack of control over valid boundaries. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

Details have emerged about a now-patched actively exploited security flaw in Microsoft Windows that could be abused by a threat actor to gain elevated privileges on affected systems. The vulnerability, tracked as CVE-2023-29336, is rated 7.8 for severity and concerns an elevation of privilege bug...
CVE-2023-2898
There is a null-pointer-dereference flaw found in f2fswriteendio in fs/f2fs/data.c in the Linux kernel. This flaw allows a local privileged user to cause a denial of service problem...
kernel: drm/ttm: Fix dummy res NULL ptr deref bug
A flaw was found in the ttm module in the Linux kernel. A NULL pointer dereference can be triggered due to an improper check, resulting in a denial of service...
kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option
A flaw was found in the Linux kernel. The PTRACESEIZE code path allows attackers to bypass intended restrictions on setting the PTSUSPENDSECCOMP flag, possibly disabling seccomp...
kernel: BSS list corruption in cfg80211_add_nontrans_list in net/wireless/scan.c
A list corruption flaw was found in cfg80211addnontranslist in the net/wireless/scan.c function in the Linux kernel. This flaw could lead to a denial of service...
kernel: ext4: don't set up encryption key during jbd2 transaction
A flaw exists in the ext4 filesystem implementation in the Linux kernel such that the function ext4unlink extended a journaling transaction too far so that it included a call to ext4findentry. However, ext4findentry may need to set up a directory’s encryption key — which can cause a deadlock when...
