SUSE CVE-2026-64088
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix negative ttbufflen batadvorignode::ttbufflen was declared as s16, but the field is never intended to hold a negative value. When a value greater than 32767 is assigned, it wraps to a negative signed integer. I...
SUSE CVE-2026-64089
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix negative lastchangesetlen batadvpivtt::lastchangesetlen len was declared as s16, but the field is never intended to hold a negative value. When a value greater than 32767 is assigned, it wraps to a negative...
SUSE CVE-2026-64090
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: avoid empty VLAN responses The commit 16116dac2339 "batman-adv: prevent TT request storms by not sending inconsistent TT TLVLs" added checks to the local direct TT response code. But the response can also be done...
SUSE CVE-2026-64091
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix TOCTOU race for reported vlans The local TT based TVLV is generated by first checking the number of VLANs which have at least one TT entry. A new buffer with the correct size for the VLANs is then allocated...
SUSE CVE-2026-64092
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: fix tpvars reference leak in receiver shutdown The receiver shutdown timer handler, batadvtpreceivershutdown, is responsible for releasing the tpvars reference it holds. However, the existing logic for...
SUSE CVE-2026-64093
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: directly shut down timer on cleanup batadvtpsendercleanup was calling timerdeletesync followed by timerdelete to guard against the timer handler re-arming itself between the two calls. This double-deletion ha...
SUSE CVE-2026-64095
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: avoid double decrement of bla.numrequests The bla.numrequests is increased when no requestsent was in progress. And it is decremented in various places announcement was received, backbone is purged, periodic work...
SUSE CVE-2026-64096
In the Linux kernel, the following vulnerability has been resolved: batman-adv: mcast: fix use-after-free in orignode RCU release batadvmcastpurgeorig removes entries from RCU-protected hlists but does not wait for an RCU grace period before returning. Concurrent RCU readers may still accesses...
CVE-2026-64088
A flaw was found in the Linux kernel's batman-adv component. An integer overflow vulnerability exists where the 'ttbufflen' variable, intended to be a positive length, can become a negative value. This occurs when a large value is assigned, causing it to wrap around. This incorrect negative value...
CVE-2026-64093
A flaw was found in the batman-adv component of the Linux kernel. A race condition exists where a timer can be re-armed after its associated reference has been removed during cleanup. This can occur when batadvtpsendercleanup attempts to shut down a timer, but a separate execution context re-arms...
CVE-2026-63836
A flaw was found in the Linux kernel. Specifically, within the batman-adv throughput meter, an arithmetic overflow in the batadvtpupdatecwnd function can cause a division by zero. This issue can lead to a kernel panic, resulting in a Denial of Service DoS for the affected system...
CVE-2026-63835
A flaw was found in the Linux kernel's Better Approach To Mobile Ad-hoc Networking batman-adv module. When a batman-adv interface is disabled, the system can still queue network packets skbs for aggregation. These packets are not properly freed, leading to a memory leak. This can result in resour...
CVE-2026-64092
A flaw was found in the Linux kernel's batman-adv module, specifically within the tpmeter component. The batadvtpreceivershutdown function, responsible for releasing tpvars references, contains flawed logic for coordinating this release during receiver shutdown. This can lead to a reference leak,...
CVE-2026-64091
A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced component. A time-of-check to time-of-use TOCTOU race condition exists when processing reported VLANs. This occurs because the buffer size for VLAN entries is calculated before the entries are...
CVE-2026-64089
A flaw was found in the Linux kernel's batman-adv module. An integer overflow vulnerability in the lastchangesetlen field can cause it to become a negative value. This leads to a buffer being improperly initialized, potentially exposing sensitive information. A local attacker could exploit this t...
CVE-2026-64096
A flaw was found in the batman-adv Better Approach To Mobile Ad-hoc Networking multicast mcast module of the Linux kernel. The batadvmcastpurgeorig function removes entries from RCU Read-Copy-Update-protected lists without ensuring that all active readers have finished accessing those entries. Th...
CVE-2026-64094
A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced component, specifically within its Bridge Loop Avoidance BLA feature. This vulnerability occurs when a network interface is unexpectedly removed while the system attempts to send an Address...
CVE-2026-64090
A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced translation table module. This vulnerability could allow an attacker to cause network instability or a denial of service DoS. The issue arises from the system sending inconsistent translation...
CVE-2026-63834
A flaw was found in the Linux kernel's batman-adv throughput meter. A remote attacker could exploit an unbound list of unacknowledged packets by sending specially crafted messages. This could force the system to allocate excessive memory or waste significant CPU cycles, leading to a Denial of...
