K000162918: Linux kernel vulnerability CVE-2026-52927
Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: fix OOB read in compatmtwfromuser Luxiao Xu says: The function compatmtwfromuser converts ebtables extensions from 32-bit user structures to kernel native structures. However, it...
CVE-2026-64413
A flaw was found in the Linux kernel's netfilter ebtables component. This vulnerability involves an uninitialized pointer free that can occur when the system's CPU mask is sparse and a memory allocation fails. Under these specific and unlikely conditions, the kernel might attempt to free an...
CVE-2026-64412
A flaw was found in the Linux kernel's netfilter ebtables component. A local attacker could exploit this vulnerability by providing a specially crafted module name that is not properly null-terminated. This improper string handling could lead to a buffer over-read when the requestmodule function...
CVE-2026-64411
A flaw was found in the Linux kernel's netfilter ebtables component. A local user could exploit this vulnerability by providing a specially crafted table name that is not properly terminated. This improper handling of the table name can lead to a stack-out-of-bounds read, potentially causing a...
SUSE CVE-2026-64411
In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: terminate table name before findtablelock updatecounters and compatupdatecounters forward a user-supplied 32-byte table name to findtablelock without NUL-terminating it. On a lookup miss, findinlistlock calls...

SUSE CVE-2026-64413
In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: zero chainstack array sashiko reports: looking at ebtables table translation, could a sparse cpupossiblemask lead to an uninitialized pointer free? If cpupossiblemask is sparse for example, CPU 0 and CPU 2 ar...

CVE-2026-64413
CVE-2026-64413 relates to the Linux kernel netfilter/ebtables path, specifically the zero chainstack array issue. The advisory describes that if cpu_possible_mask is sparse (e.g., CPU 0 and CPU 2 possible, CPU 1 not), the allocation loop can skip an entry and, if vmalloc_node() fails later, the c...
