Name of the Vulnerable Software and Affected Versions IBM AIX versions 7.2 and 7.3 IBM PowerVM VIOS version 4.1 Description An out-of-bounds read allows a local attacker to disclose sensitive kernel memory. An out-of-bounds read occurs when a program reads data past the end of the intended buffer...

CVE-2026-12522 Stack buffer overflow in Zephyr hl7800 modem driver parsing network-supplied +CGCONTRDP address fields

The HL7800 cellular modem driver's +CGCONTRDP: response handler oncmdatcmdinfoipaddr in drivers/modem/vendorstandalone/hl7800.c parses the PDP-context dynamic parameters local address, subnet mask, gateway, and DNS servers that the cellular network assigns to the device. The response is linearize...

CVE-2026-12633 Out-of-bounds write in IPv6 6LoWPAN Context Option handling via unauthenticated Router Advertisement

The IPv6 neighbor-discovery code in subsys/net/ip/ipv6nbr.c processes the 6LoWPAN Context Option 6CO, RFC 6775 carried inside ICMPv6 Router Advertisements. In handlera6co the 8-bit contextlen field is taken directly from the packet and was never bounded to the RFC maximum of 128. The function...

CVE-2026-12633

CVE-2026-12633 is an out-of-bounds write in the Zephyr RTOS IPv6 neighbor-discovery code (subsys/net/ip/ipv6_nbr.c). The function handle_ra_6co() processes the 6LoWPAN Context Option (RFC 6775) from ICMPv6 Router Advertisements without bounding the 8-bit context_len field to the RFC maximum of 12...

CVE-2026-16833

IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 have an out-of-bounds read allowing remote, unauthenticated kernel memory disclosure (CVSS 5.3, MEDIUM). IBM support page is the only reference; no exploitation details provided.

CVE-2026-72488

A flaw was found in the Linux kernel's soundwire component. An out-of-bounds memory access can occur within the sdwaddelementgroupcount function due to an incorrect loop condition. This error allows the system to attempt to access memory beyond its allocated buffer. Such an issue could lead to...

CVE-2026-49428 posixshm: system calls can incorrectly free memory of largepage objects

Certain system calls, such open2 with the OTRUNC flag set, and fspacectl2, could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug to access freed kernel...

CVE-2026-49427 posixshm: largepage shared memory objects not explicitly wired

Pages belonging to largepage shared memory objects were not explicitly wired. When sendfile2 transmitted such an object with the SFNOCACHE flag, it freed the underlying pages after transmission even though existing mappings still referred to them. An unprivileged local user can abuse the bug to...

CVE-2026-49427 posixshm: largepage shared memory objects not explicitly wired

CVE-2026-49427

The FreeBSD kernel's posixshm module contains a vulnerability where pages belonging to largepage shared memory objects were not explicitly wired. When sendfile(2) transmits such an object with the SF_NOCACHE flag, it incorrectly frees the underlying pages while existing mappings still refer to th...

EUVD-2026-62240

The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption...

CVE-2026-49430

The OpenZFS component in FreeBSD contains a kernel memory corruption vulnerability (integer overflow) within the ZFS_IOC_RECV_NEW ioctl in the heal receive path. The issue arises because a 64-bit payload size is truncated to a 32-bit integer for memory allocation, but the original 64-bit size is ...

EUVD-2026-62239

The ZFSIOCUSERSPACEMANY ioctl, used by zfs-userspace8, truncated a 64-bit output buffer size to a 32-bit integer for the kernel allocation, but used the original 64-bit size as the buffer limit when writing records. A local user with the "userused" delegated ZFS permission can trigger a kernel he...
