kernel: Linux kernel: netfilter: ebtables SNAT target writes to shared memory pages during ARP hardware address rewrite

A flaw was found in the Linux kernel's netfilter bridge ebtables SNAT Source Network Address Translation module. This vulnerability allows a local attacker on a system configured with specific bridge netfilter rules to improperly modify underlying memory pages during an ARP Address Resolution...

CVE-2026-53266

The CVE-2026-53266 entry concerns the Linux kernel netfilter bridge path, where ebt_snat ARP sender hardware address rewrite could be performed on non-writable memory. Root cause: ARP SHA is written via skb_store_bits() relative to skb->data, and skb_header_pointer() only safely reads the ARP ...

CVE-2026-53219 netfilter: x_tables: avoid leaking percpu counter pointers

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtables: avoid leaking percpu counter pointers The native and compat get-entries paths copy the fixed rule entry header from the kernelized rule blob to userspace before overwriting the entry's counter fields with a...

CVE-2026-47382

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the connection-test endpoint opened a raw TCP socket to the user-supplied database host without resolving and range-checking the destination, so private and link-local addresses including IPv4-mapped IPv6 forms and...

CVE-2026-45970

A flaw was found in the Linux kernel's bonding driver, specifically within the Active-Backup Load Balancing ALB receive path. A local attacker can trigger a Use-After-Free UAF vulnerability in the rlbarprecv function by rapidly bringing a bond interface up and down while receiving Address...

In the Linux kernel, the following vulnerability has been resolved: netfilter: arptables: fix IEEE1394 ARP payload parsing Weiming Shi says: "arppacketmatch unconditionally parses the ARP payload assuming two hardware addresses are present source and target. However, IPv4-over-IEEE1394 ARP RFC 27...

CVE-2026-45844

A flaw was found in the Linux kernel's netfilter ARP Address Resolution Protocol tables. When processing IPv4-over-IEEE1394 ARP packets on IEEE1394 interfaces, the kernel incorrectly parses the ARP payload. This can lead to incorrect filtering decisions by arptables, where packets that should be...

CVE-2026-45970 bonding: alb: fix UAF in rlb_arp_recv during bond up/down

In the Linux kernel, the following vulnerability has been resolved: bonding: alb: fix UAF in rlbarprecv during bond up/down The ALB RX path may access rxhashtbl concurrently with bond teardown. During rapid bond up/down cycles, rlbdeinitialize frees rxhashtbl while RX handlers are still running,...
