CVE-2026-45970

CVE-2026-45970 affects the Linux kernel bonding driver (Active-Backup Load Balancing, ALB). The root cause is a Use-After-Free in rlb_arp_recv where RX path may access rx_hashtbl concurrently with bond teardown, allowing a race with rlb_deinitialize() to dereference freed memory and trigger a ker...

UBUNTU-CVE-2026-45842

In the Linux kernel, the following vulnerability has been resolved: slip: reject VJ receive packets on instances with no rstate array slhcinit accepts rslots == 0 as a valid configuration, with the documented meaning of 'no receive compression'. In that case the allocation loop in slhcinit is...

CVE-2026-45842

CVE-2026-45842 concerns the Linux kernel slip module. When rslots are configured to 0 (no receive compression), the code may allocate a NULL rstate and set rslot_limit to 0. The receive path does not guard against this, causing slhc_uncompress() to dereference comp->rstate[x] if the VJ header ...

CVE-2026-43373

The CVE-2026-43373 entry describes a Linux kernel vulnerability in the net: ncsi subsystem. Early return paths in NCSI RX and AEN handlers fail to release received skbuffers (skb) when processing invalid AEN packets or failing to resolve NCSI devices/handlers, leading to a memory leak. The impact...
