Fix it by treating ICE_VSI_LB VSIs slightly more like normal PF VSIs and letting them have a q_vector. It's just a dummy, because the loopback test does not use interrupts, but it contains a napi struct that can be passed to libeth_rx_fq_create() called from ice_vsi_cfg_rxq() -> ice_rxq_pp_create().
CVE-2026-82946 2026-10-26 N/A 6.5 MEDIUM
SOEM version 2.0.0 and earlier contains a vulnerability where a malicious device can crash the master system. When the software receives an error response, it clears an internal pointer but continues processing. If another message arrives before timeout, the software attempts to use the cleared pointer, causing a crash. An attacker can trigger this with a simple sequence of two messages.
CVE-2026-111144 2026-10-26 N/A 5.5 MEDIUM
libansilove 1.3.0 through 1.4.2 contains a NULL pointer dereference vulnerability in ansilove_xbin() that allows attackers to crash applications by supplying a crafted XBIN file. Attackers can set the 512-character flag without the custom-font flag, causing drawchar() to index a NULL high_font_data_xbin pointer and terminate the process.
CVE-2026-111129 2026-10-26 N/A 5.5 MEDIUM
Open Asset Import Library (assimp) through 6.0.5 contains a NULL pointer dereference vulnerability in the Ogre3D binary mesh importer's OgreBinarySerializer::ReadAnimationKeyFrames() handling of unvalidated animation track targets. Attackers can supply a crafted .mesh file with a morph animation track targeting a missing submesh or absent shared geometry to crash the host process.
CVE-2026-44638 1 Saitoha 1 Libsixel 2026-10-26 N/A 2.5 LOW
libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. From to 1.8.7-r1, a wrong NULL check after an allocation call in sixel_decode_raw and sixel_decode causes a NULL pointer dereference whenever the allocation fails. The check tests the address of the output parameter (always non-NULL) instead of the value the malloc returned. On allocation failure, the function continues and writes through a NULL pointer, crashing the process. This is a denial of service against any caller of these public APIs that hits a low-memory condition. This vulnerability is fixed in 1.8.7-r2.
CVE-2026-42409 1 F5 23 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Advanced Web Application Firewall and 20 more 2026-10-26 N/A 7.5 HIGH
When an HTTP/2 profile and an iRule containing the HTTP::redirect or HTTP::respond command are configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) process to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

CVE-2026-32849 2026-10-26 N/A 5.5 MEDIUM
NetBSD prior to commit ec8451e contains a signed integer overflow vulnerability in the cryptodev_op() function in sys/opencrypto/cryptodev.c where the local variable iov_len is declared as a signed int but assigned from an unsigned cop->dst_len value, causing undefined behavior when cop->dst_len exceeds INT_MAX. A local attacker with access to /dev/crypto and a compression session type can exploit this vulnerability by providing a dst_len value exceeding INT_MAX to trigger a kernel panic through NULL pointer dereference when CONFIG_SVS is disabled and corrupted UIO pointer arithmetic.
CVE-2026-44710 2026-10-26 N/A 4.6 MEDIUM
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, src/device.c passed the return values of udisks_drive_get_serial(), udisks_drive_get_vendor(), and udisks_drive_get_model() directly to strcmp() without NULL checks. The GIO/UDisks API documentation states these accessors can return NULL for devices that do not expose the corresponding field. Passing NULL to strcmp() is undefined behaviour (typically a SIGSEGV). This vulnerability is fixed in 0.8.7.
CVE-2026-8360 2026-10-26 N/A 7.5 HIGH
Function calls to WOSCommonUtil.dll!WOSSysInfoGetDeviceInterface() in various DLLs (i.e., WOSProfileMgrModule.dll, WOSWebDavModule.dll) can return a NULL pointer (i.e., when no user is logged into the Triofox Server Agent Management Console). The returned NULL pointer is not checked before being dereferenced.
CVE-2026-48985 2026-10-26 N/A 5.5 MEDIUM
pam_usb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, pusb_is_loginctl_local() can cause a NULL dereference crash when parsing loginctl output. The function calls popen() and reads the result; if the Remote field is only a newline, fgets() succeeds but strtok_r(buf, "\n", &saveptr) returns NULL. A subsequent strcmp(is_remote, "no") then dereferences NULL, causing undefined behavior (typically SIGSEGV) and crashing the PAM module. This can crash the authenticating process (e.g., sudo, login) and, depending on PAM stack configuration, deny access for all users of the affected service. This issue has been fixed in version 0.9.2.
CVE-2026-75618 1 Tp-link 4 Tapo C100, Tapo C100 Firmware, Tapo C101 and 1 more 2026-10-26 N/A 6.5 MEDIUM
Tapo C100/C101 V5 contains a null pointer dereference vulnerability in the RTSP service. An attacker on the local network can send specially crafted requests that cause the service to dereference an invalid pointer, resulting in a service crash and device reboot. Successful exploitation can disrupt live video streaming functionality and cause a temporary denial-of-service condition.
CVE-2026-48066 2026-10-26 N/A 5.7 MEDIUM
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, src/log.c contains a process-wide static pointer that is written on every PAM invocation with the address of a stack-local variable. This violates the PAM re-entrancy requirement and creates a data race when the PAM stack is invoked concurrently from multiple threads. This vulnerability is fixed in 0.9.1.
CVE-2026-47271 2026-10-26 N/A 5.1 MEDIUM
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, src/mem.c implemented out-of-memory guards for xmalloc(), xrealloc(), and xstrdup() using assert(data != NULL). The C standard specifies that all assert() expressions are compiled out when NDEBUG is defined at build time. NDEBUG is commonly defined in release and packaging builds (Debian, Fedora, Arch package flags all define it via -DNDEBUG in CFLAGS). With the guard removed, xmalloc/xrealloc/xstrdup silently return NULL on allocation failure. Every caller in the codebase dereferences the return value without a NULL check -- this is the intended design, as the guard was supposed to abort before the dereference. With the guard gone, any allocation failure causes a NULL pointer dereference, crashing the PAM module. A crash in a PAM module loaded by sudo or login causes authentication to fail for the duration of the crash, creating a local denial-of-service condition. An attacker who can induce memory pressure at authentication time can lock all users out of sudo and login. This vulnerability is fixed in 0.9.0.
CVE-2026-16829 1 Ibm 2 Aix, Vios 2026-10-26 N/A 5.3 MEDIUM
IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to a NULL pointer dereference.
