Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: nfp: flower: handling of actinetdevs allocation failures The kmallocarray function in nfpfllagdowork will return null if physical memory runs out. As a result, if we dereference actinetdevs, null pointer dereferencing bugs may...

SUSE CVE-2026-64585

In the Linux kernel, the following vulnerability has been resolved: can: esdusb: kill anchored URBs before freeing netdevs esdusbdisconnect frees each CAN netdev with freecandev inside its per-netdev loop and only calls unlinkallurbsdev afterwards. The per-netdev private data struct esdusbnetpriv...

CVE-2026-64585

CVE-2026-64585 (Linux kernel): The issue affects the CAN esd_usb subsystem where, after free_candev runs, net_device pointers in priv->tx contexts are dereferenced, leading to use-after-free when killing anchored URBs. The fix reorders teardown to stop TX queues first, then call unlink_all_urb...

CVE-2026-22981

In the Linux kernel, the following vulnerability has been resolved: idpf: detach and close netdevs while handling a reset Protect the reset path from callbacks by setting the netdevs to detached state and close any netdevs in UP state until the reset handling has completed. During a reset, the...

CVE-2025-39796

CVE-2025-39796 affects the Linux kernel (net: lapbether: ignore ops-locked netdevs). According to connected sources, Syzkaller-triggered lock dependency via xsk_notify and register_netdevice could occur for notifier chains, with the fix skipping lapbeth for ops-locked devices to break the depende...

kernel: nfp: flower: handle acti_netdevs allocation failure

A vulnerability was found in the Linux kernel's ethernet lagconf.c driver in the nfpfllagdowork function, where a NULL pointer dereference can occur due to a lack of proper checks. The scenario is caused when the function attempts to call kmallocarray, which returns as NULL because the physical...

CVE-2024-38557 net/mlx5: Reload only IB representors upon lag disable/enable

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Reload only IB representors upon lag disable/enable On lag disable, the bond IB device along with all of its representors are destroyed, and then the slaves' representors get reloaded. In case the slave IB representor...
