CVE-2026-49412
The kernel handler for IPV6MSFILTER dropped a serializing lock in order to copy the source-filter list from userspace, then reacquired the lock. During this window another thread could free the multicast filter structure, leaving the handler with a stale pointer to freed memory. An unprivileged...
CVE-2026-49412 Use-after-free bug in the IPV6_MSFILTER socket option handler
The kernel handler for IPV6MSFILTER dropped a serializing lock in order to copy the source-filter list from userspace, then reacquired the lock. During this window another thread could free the multicast filter structure, leaving the handler with a stale pointer to freed memory. An unprivileged...

CVE-2026-49412
The CVE-2026-49412 issue affects FreeBSD’s IPv6_MSFILTER in the kernel: the handler drops a serializing lock to copy the source-filter list and later reacquires it, creating a window where another thread can free the multicast filter structure and leave a stale pointer. This use-after-free enable...

Linux Kernel Memory Error Reference Vulnerability (CNVD-2026-25961)
The Linux kernel is an open-source operating system kernel that provides core functions such as process management, memory management, network protocol stack, and hardware drivers. The Linux kernel has a memory error reference vulnerability. This vulnerability arises from processing MLD queries,...
PT-2026-53062
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the kernel handler for IPV6 MSFILTER. The handler drops a serializing lock to copy the source-filter list from userspace and subsequently reacquires it...
SUSE CVE-2026-53263
In the Linux kernel, the following vulnerability has been resolved: 6lowpan: fix off-by-one in multicast context address compression The second memcpy in lowpaniphcmcastctxaddrcompress uses &data1 as destination and &ipaddr-s6addr11 as source, but both should be offset by one: &data2 and...
SUSE CVE-2026-53275
In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: Fix use-after-free when processing MLD queries When processing an MLD query, a pointer to the multicast group address is retrieved when initially parsing the packet. This pointer is later dereferenced without being...
CVE-2026-53263
A flaw was found in the Linux kernel's 6lowpan component. An off-by-one error during multicast context address compression can lead to the transmission of uninitialized kernel stack memory over the network. This vulnerability results in information disclosure, potentially allowing an attacker to...
CVE-2026-53275
A flaw was found in the Linux kernel's IPv6 multicast mcast component. When processing Multicast Listener Discovery MLD queries, a pointer to the multicast group address is not correctly reloaded after certain packet manipulations. This can lead to a use-after-free vulnerability, potentially...
