CVE-2026-80558

A flaw was found in libceph within the Linux kernel. A remote attacker, by sending a specially crafted or corrupted OSD map osdmap from a Ceph monitor or OSD, could cause the system to attempt to access memory outside of allocated bounds. This out-of-bounds access occurs because invalid OSD indic...

CVE-2026-74736

A flaw was found in the Linux kernel's clsbpf component. A device-bound program could be incorrectly attached to a different network device than it was intended for. This misconfiguration could allow an attacker to trigger a system panic, leading to a denial of service, if the original device is...

CVE-2026-74750

A flaw was found in the Linux kernel's ovpn module. This vulnerability arises from an incorrect handling of cryptographic resource freeing, where a function that requires the ability to pause sleep is executed in a context that does not allow it. This improper resource management could lead to...

CVE-2026-80527

A flaw was found in the Linux kernel's Ceph client. A reader can experience an indefinite hang when the client's local capability state mdswanted becomes stale after a Metadata Server MDS capability revocation. This occurs because the client believes it still wants a capability e.g., FILERD that...

CVE-2026-74738

A flaw was found in the regmap: sdw-mbq component of the Linux kernel. This vulnerability occurs when the regmapsdwmbqpollbusy function attempts to call an unset readablereg callback. If a device responds with COMMANDIGNORED, it can lead to a NULL function pointer dereference. This could...

CVE-2026-80523

A flaw was found in the Linux kernel. The HDMA Hardware Direct Memory Access clock, responsible for the internal TCM Tightly Coupled Memory access path of the X100 RISC-V core, was not set as critical. This oversight allows the clock to be shut off, which can lead to a system hang, for example,...

CVE-2026-80562

A flaw was found in the Linux kernel's gpio: ml-ioh component. An incorrect spinlock type spinlockt was used in interrupt handling routines where a non-sleeping lock rawspinlockt was required. This could lead to invalid lock acquisition, potentially causing system instability or a denial of...

CVE-2026-80553

A flaw was found in the s390/vfioccw component of the Linux kernel. This vulnerability arises from the improper management of workqueues, where existing tasks might not be canceled before associated resources are released. A local attacker could potentially leverage this issue to trigger a...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

EUVD-2026-66985

Improper validation of memory boundaries in WibuKey64.sys of WibuKey up to 6.70 for Windows can be exploited by an attacker by setting the pointers outside the scope of the program. This usually results in a denial of service, yet we cannot rule out the possibility of exploits that can cause Remo...

CVE-2026-81581 User input in WibuKey is used (without proper sanitization) to compute the address of a pointer, which can be exploited to let the user point to any storage, to which Windows responds with a denial of service.

Improper validation of memory boundaries in WibuKey64.sys of WibuKey up to 6.70 for Windows can be exploited by an attacker by setting the pointers outside the scope of the program. This usually results in a denial of service, yet we cannot rule out the possibility of exploits that can cause Remo...

CVE-2026-81581

WibuKey up to 6.70 for Windows contains an improper validation of memory boundaries vulnerability in its WibuKey64.sys kernel driver. User input is used without proper sanitization to compute a pointer address, allowing an attacker to point to arbitrary memory outside the driver's scope. The typi...

CVE-2026-80557

A flaw was found in the kernel's libceph component. A malicious or compromised Ceph Object Storage Daemon OSD can send a specially crafted message that causes an out-of-bounds read when processing watcher information. This vulnerability can lead to memory corruption or a denial of service,...

EUVD-2026-66982

If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 accepts requests with opcode 0x5e, which contain the data length and the data itself. Missing bounds checking on the data length value can lead to out of bounds reads, causing a segmentation fault that ultimately crashes...

CVE-2026-81575 Missing Sanity Checks for Buffer Lengths

If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 accepts requests with opcode 0x5e, which contain the data length and the data itself. Missing bounds checking on the data length value can lead to out of bounds reads, causing a segmentation fault that ultimately crashes...

CVE-2026-81575

CodeMeter Runtime (WIBU) prior to versions 8.41a and 9.10 is vulnerable when configured as a server. Requests carrying opcode 0x5e include a data-length field that lacks bounds checking, allowing an attacker to trigger out-of-bounds reads that result in a segmentation fault and crash the Runtime....

CVE-2026-81574 Format String Vulnerability in Logger

In CodeMeter Runtime before versions 8.41a and 9.10, the logger does not sanitize input strings in certain cases, allowing an attacker to inject printf-style format specifiers. This can be used to reliably crash CodeMeter and disclose sensitive information such as process memory and stack canarie...

CVE-2026-81574

CodeMeter Runtime versions prior to 8.41a and 9.10 are affected by a format string vulnerability in the logger component, which fails to sanitize input strings in certain cases, allowing injection of printf-style format specifiers . An attacker can reliably crash CodeMeter and disclose sensitive ...

CVE-2026-74743

A flaw was found in the Linux kernel's macvlan component. The macvlan component incorrectly initializes network packet buffer skb headroom and tailroom values, failing to inherit them from the underlying network device. This can occur when the underlying device requires additional space for heade...
